Before any behaviour problem can be effectively addressed, a veterinarian must rule out medical causes. This is one of the most critical and commonly missed steps in behavioural management.

A cat that stops using the litter box may not have a “litter box attitude” — they may have a urinary tract infection that makes urination painful, and they are avoiding the litter box because they associate it with pain.

A dog that snaps when touched may not be “dominant” — they may have arthritis, an ear infection, a skin condition, or another painful condition they cannot express verbally.

A previously house-trained dog that begins having accidents indoors may not have “forgotten” their training — they may have developing kidney disease, diabetes, or a neurological issue.

This is why the first step at Diamond Claw when an owner brings a behavioural concern is always a thorough physical examination and appropriate diagnostic testing — not immediately prescribing a behavioural modification programme.

Once medical causes are excluded, we can properly assess whether the issue is behavioural, emotional, or a combination of both.

Common Behaviour Problems in Dogs — and What They Usually Mean

Separation Anxiety

Separation anxiety is one of the most common behavioural diagnoses in dogs. It is characterised by distress that occurs specifically when the dog is left alone or separated from their primary attachment figure. It is not simply missing the owner — it is genuine emotional panic triggered by isolation.

Signs of separation anxiety in dogs:

• Barking, howling, or whining that begins when the owner leaves and continues for extended periods
• Destructive behaviour (chewing furniture, doors, or belongings) targeted at escape routes or the owner’s items
• Toileting accidents in house-trained dogs, only occurring when alone
• Excessive salivation, panting, or pacing when alone
• Signs of distress as departure cues approach — pacing when the owner picks up keys, for example

Separation anxiety has a significant genetic component, and it is also worsened by sudden changes in routine — which are particularly common for pets in expat households in the UAE, where owners may travel frequently or working patterns change.

What helps: Behaviour modification using systematic desensitisation (gradually increasing alone-time tolerance), environmental enrichment, appropriate exercise, and in moderate-to-severe cases, medication prescribed by a veterinarian. This is not a condition that resolves with punishment or simply “leaving the dog to get used to it.” Early, structured intervention leads to significantly better outcomes.

Excessive Barking

Barking is a natural communication tool for dogs. Excessive or persistent barking is a symptom of an unmet need, not a personality flaw. The most common underlying causes are boredom and insufficient mental stimulation; anxiety (including separation anxiety); territorial behaviour triggered by passing people, animals, or vehicles; attention-seeking that has been inadvertently reinforced; fear; or noise sensitivity.

In UAE contexts specifically, the noise and activity of shared residential buildings, the sound of construction, and the call to prayer — which some dogs react to — are common barking triggers that owners discuss with us.

Identifying and addressing the underlying cause is always more effective than attempting to suppress the barking through punishment, which typically worsens anxiety-driven barking.

Fear and Noise Phobia

Fear responses in dogs exist on a spectrum. A mild startle response to a sudden loud sound is normal. A dog that cannot function, hides, trembles, salivates, or attempts to escape in response to specific triggers — thunder, fireworks, car backfires, or other stimuli — has a phobia that causes genuine suffering.

In Sharjah and the UAE, fireworks during celebrations are a particularly significant trigger for noise-phobic pets. Planning ahead for these occasions — by consulting your vet about situational medication, creating a safe den environment, using noise-cancelling white noise, and keeping pets indoors — can significantly reduce their distress.

Aggression

Aggression in dogs is the behaviour problem that most urgently requires professional veterinary and behavioural assessment. It is never safe to attempt to manage aggression through punishment, dominance-based techniques, or simply hoping it resolves on its own.

Aggression has many different underlying causes and presentations — fear-based aggression, pain-induced aggression, resource guarding, redirected aggression — each requiring a different approach. A bite that breaks skin is always a serious incident and should be discussed with a veterinary professional promptly.

Pets are biologically programmed to mask illness and pain. This instinct is rooted in their evolutionary history: in the wild, an animal that shows weakness becomes a target for predators. Domestic pets retain this instinct deeply, meaning they will often eat, play, and maintain their normal social behaviour even when dealing with significant internal illness or chronic pain.

This is not deception — it is survival biology. But it means that relying on your pet’s outward behaviour as your sole indicator of their health will almost always result in missing things that are genuinely important.

Consider these realities:

• Early kidney disease in cats produces no symptoms until approximately two-thirds of kidney function has already been lost
• Heart murmurs in dogs can be present for months or years before causing any clinical signs
• Dental disease is painful and progressive, but most pets continue eating through significant oral pain
• Early cancer is frequently asymptomatic — many tumours are discovered incidentally during wellness examinations

A wellness exam finds these things. A visit driven only by visible illness usually does not — not until significant damage has already occurred.

What Actually Happens During a Pet Wellness Exam at Diamond Claw

A wellness examination is far more thorough than most owners expect. At Diamond Claw, a comprehensive wellness visit includes:

Complete Physical Examination — Nose to Tail

Your veterinarian systematically evaluates every body system:

Eyes: Clarity, pupil responses, signs of pressure changes, surface changes, and retinal assessment in some cases.

Ears: Presence of infection, inflammation, mite infestation, foreign bodies, or early signs of chronic ear disease — common in floppy-eared breeds and particularly in Sharjah’s humidity.

Mouth and teeth: Assessment of gum colour and health, plaque and tartar level, tooth integrity, and signs of oral infection — the most common condition diagnosed in adult pets and one of the most commonly missed.

Lymph nodes: Palpation of key lymph nodes throughout the body — early enlargement is one of the first signs of infection or lymphoma.

Heart and lungs: Auscultation (listening with a stethoscope) to assess heart rate, rhythm, and the presence of murmurs or abnormal breath sounds.

Abdomen: Gentle palpation to assess organ size, consistency, and the presence of pain, masses, or distension.

Skin and coat: Assessment of coat quality, skin condition, signs of parasites, lumps, lesions, and allergic skin disease — a very common condition in UAE pets.

Musculoskeletal system: Assessment of gait, joint flexibility, muscle mass, and pain responses — particularly important for detecting early arthritis in older pets.

Body weight and body condition score: A precise weight and body condition assessment at every visit allows your vet to identify trends — gradual weight loss or gain that an owner may not notice at home because they see their pet every day.

Neurological brief assessment: Basic reflexes, balance, and responses that may indicate neurological changes.

Recommended Diagnostics at Wellness Visits

Based on your pet’s age, species, breed, and health history, your vet may recommend adding:

Blood work (complete blood count and chemistry panel): Assesses red and white blood cell health, kidney function, liver function, blood sugar, electrolyte balance, and more. This is how kidney disease, liver disease, diabetes, anaemia, and infection are detected before visible symptoms develop.

Urinalysis: Assesses kidney function, hydration, the presence of infection, crystals, or protein — critical for cats in particular, who are highly prone to kidney disease.

Faecal parasite screen: Identifies intestinal parasites that are not always visible and that can be transmitted to human family members.

Blood pressure measurement: High blood pressure (hypertension) is common in older cats with kidney disease or hyperthyroidism, and is entirely without obvious symptoms. It causes progressive damage to the eyes, kidneys, heart, and brain if undetected.

Thyroid testing: Recommended for cats from middle age onward, given the high prevalence of hyperthyroidism in older felines.

Vaccination and Parasite Prevention Review

Every wellness visit includes a review of your pet’s vaccination status — ensuring that core vaccines including the legally required rabies vaccination are current — and an assessment of whether parasite prevention protocols are appropriate and up to date.

Nutrition and Weight Assessment

Your vet will assess your pet’s current diet, feeding amounts, body condition score, and weight trend — recommending adjustments if your pet is underweight, overweight, or if their nutritional needs have changed with age or health status.

A Conversation About What You Have Noticed at Home

You are with your pet every day. You notice things a vet cannot observe in a 20-minute visit. Every wellness exam includes time for you to share anything that has changed, however small it seems — changes in sleep, appetite, drinking, energy, mood, or toileting habits. These details are clinically valuable.

There is no single age at which all pets become senior, because dogs age at different rates depending on their size and breed.

As a general guide:

One key principle: one year in a senior pet’s life can equal several human years. Changes in their health can progress quickly. This is precisely why the AAHA recommends twice-yearly wellness examinations for senior pets — not because something is necessarily wrong, but because the window for catching conditions before they become serious is shorter.

The Most Common Health Conditions in Senior Pets

Osteoarthritis (Joint Disease)

Arthritis is one of the most widespread and most underdiagnosed conditions in older pets. Research suggests that over 60% of dogs experience some degree of arthritis, and the condition is similarly common in older cats. Yet because pets instinctively hide pain and adapt their movement gradually over time, many owners do not recognise it until it is well advanced.

Signs of arthritis in dogs: Reluctance to jump, climb stairs, or rise from rest; stiffness in the mornings that improves as the pet warms up; reduced activity and play; lagging on walks; occasionally licking or chewing at painful joints.

Signs of arthritis in cats: Reduced jumping height or avoidance of furniture they previously used effortlessly; reluctance to use a litter box with high sides; grooming changes (less able to reach certain areas, or overgrooming painful joints); reduced activity and interaction.

Modern veterinary management of osteoarthritis includes several well-evidenced approaches: appropriate pain medication, anti-inflammatory therapy, weight management (reducing the load on painful joints), therapeutic nutrition including omega-3 fatty acids (which have demonstrated analgesic effects in peer-reviewed research), and in some cases, physiotherapy and mobility aids.

Important: Never give your pet human pain medications for arthritis. Ibuprofen, paracetamol, and naproxen are toxic to dogs and cats. Vet-prescribed pain management is both safer and more effective.

Chronic Kidney Disease (CKD)

Kidney disease is one of the most significant health concerns in older cats, and is also common in senior dogs. Data from large veterinary laboratory studies shows that CKD is detectable in over 40% of cats aged 5 to 15, and in over 80% of cats aged 15 and above.

The challenge with kidney disease is that it is clinically silent in its early stages. By the time a pet shows obvious symptoms — increased thirst and urination, weight loss, vomiting, reduced appetite — significant kidney function has already been lost. This is the core reason why routine blood and urine testing in senior pets is so valuable: it can detect kidney disease when it is early, before symptoms appear, at a stage when dietary and medical management can meaningfully slow progression and extend quality of life.

Early detection through twice-yearly wellness bloodwork is one of the most important things you can do for an older cat especially.

Cognitive Dysfunction Syndrome (CDS)

Cognitive dysfunction syndrome is the veterinary equivalent of dementia in humans. It is a recognised neurological condition associated with age-related changes in the brain, and it is more common than most pet owners realise.

The clinical signs in dogs are captured under the acronym DISHAA: Disorientation, altered Interactions (with people and other pets), changes in Sleep-wake cycles, loss of House training, altered Activity levels, and increased Anxiety. A dog who begins waking at night, pacing, seeming confused in familiar environments, or staring at walls may be showing signs of CDS rather than simply being “old and odd.”

In cats, cognitive dysfunction tends to present differently — cats often increase vocalisation (particularly at night), become clingier or more anxious, and may show confusion in familiar environments.

CDS is a diagnosis of exclusion — meaning other medical causes must be ruled out first. Once diagnosed, it can often be managed with environmental enrichment, mental stimulation, specific nutritional support, and in some cases, medication.

Dental Disease

Senior pets accumulate years of dental disease progression. By the time a dog or cat reaches senior age without consistent dental care, many will have moderate to advanced periodontal disease causing chronic pain and systemic bacterial exposure. We assess dental health at every senior wellness visit at Diamond Claw, and professional dental cleaning remains as important — often more so — in older pets as in younger ones.

Endocrine Diseases

Hypothyroidism is common in older dogs, causing weight gain, lethargy, skin changes, and hair loss. Hyperthyroidismis one of the most common diseases in older cats, causing weight loss despite increased appetite, increased thirst and urination, restlessness, and a rapid heart rate. Diabetes mellitus affects both species and becomes more common with age, particularly in obese or previously obese pets.

All of these conditions are detectable through routine blood testing and manageable with appropriate treatment. Left undetected, they significantly affect quality of life.

Periodontal disease is a progressive bacterial infection of the structures that support the teeth — the gums, the ligaments, and the bone around each tooth root. It begins with the accumulation of plaque (a film of bacteria and food particles) on the tooth surface. When plaque is not removed, it mineralises into tartar — the hard yellowish-brown crust you may have noticed on your pet’s teeth. Tartar irritates the gums and creates the conditions for bacteria to work their way deeper, below the gumline, where the real damage begins.

The American Veterinary Dental College (AVDC) classifies periodontal disease in four stages:

Stage 1 — Gingivitis: Gum redness and mild inflammation. No bone loss yet. Fully reversible with professional cleaning and consistent home care. This is the ideal time to intervene.

Stage 2 — Early Periodontitis: Tartar visible on teeth, gum inflammation increasing, early loss of the attachment between the tooth and supporting structures. Still treatable, but no longer fully reversible.

Stage 3 — Moderate Periodontitis: Significant bone loss around the tooth roots. Bacteria have established themselves in gum pockets. This stage causes genuine, ongoing pain — even if your pet shows no obvious signs of discomfort. Some teeth may need to be extracted.

Stage 4 — Advanced Periodontitis: Severe bone and tissue destruction. Teeth may be loose, dead, or abscessed. Significant pain and infection. At this stage, oral surgery and multiple extractions are often required.

Research has found that periodontitis is diagnosed in over 80% of dogs by the age of two, and rates increase significantly with age — with one study identifying disease in 96% of dogs between 12 and 14 years of age.

It’s Not Just a Mouth Problem — Dental Disease Affects the Whole Body

This is the part that surprises most pet owners the most.

When bacteria accumulate in the deep pockets of infected gums, they don’t stay in the mouth. They enter the bloodstream through inflamed, damaged gum tissue — a process that occurs regularly, and repeatedly, in pets with untreated periodontal disease. Once in circulation, these bacteria and the inflammatory signals they trigger can reach the heart, kidneys, and liver.

The associations between periodontal disease and systemic organ disease in pets are well documented in veterinary literature. In particular, the kidneys are vulnerable — one research study examining the relationship between dental disease and kidney biomarkers found that periodontal disease is associated with measurable changes in kidney function markers in both dogs and cats. This is especially significant because kidney disease is already common in older cats, and dental disease can accelerate its progression.

This is why at Diamond Claw we treat dental health as an internal medicine issue, not just a cosmetic one. A healthy mouth is part of a healthy body.

Signs That Your Pet May Have Dental Disease

Because pets are naturally inclined to hide pain and discomfort, dental disease is often silent until it is advanced. The AVDC notes that white-looking teeth are not a reliable indicator of oral health — the most serious disease exists beneath the gumline, invisible to the naked eye without dental X-rays.

That said, watch for these signs at home:

Early indicators:

• Persistent bad breath — not just post-meal odour, but an ongoing, unpleasant smell from the mouth
• Visible yellowish or brown buildup on the teeth, particularly along the gumline
• Red, swollen, or slightly bleeding gums when touched
• Excessive drooling

Signs of more advanced disease:

• Reluctance to chew hard food, or dropping food while eating
• Chewing consistently on one side of the mouth
• Pawing at the face or mouth
• Visible broken, discoloured, or loose teeth
• Swelling or asymmetry around the jaw or face
• Changes in behaviour — becoming quieter, more irritable, or less interested in play (often a sign of chronic pain that the pet cannot express)

If you notice any of these signs, do not wait for your next scheduled visit. Book a dental examination at Diamond Claw as soon as possible.

1. Difficulty Breathing 

Labored breathing, rapid shallow breaths, open-mouth breathing in cats, or blue, gray, or pale gums all signal a respiratory or cardiac emergency. 

What it might indicate: Heatstroke, allergic reaction, heart failure, fluid in the lungs, or an airway obstruction. 

Don’t wait. Come to Diamond Claw or the nearest emergency vet immediately. 

2. Collapse or Sudden Inability to Stand 

A sudden loss of the ability to stand or use the legs is a neurological or cardiovascular emergency. 

What it might indicate: Heatstroke, internal bleeding, severe low blood sugar, a neurological event, or severe anemia. 

Keep your pet calm, avoid unnecessary movement, and transport gently to a vet right away. 

3. Uncontrolled Bleeding or Deep Wounds 

Bleeding that doesn’t slow after five minutes of firm pressure, deep punctures, animal bite wounds, or wounds exposing tissue or bone all need urgent attention. 

Apply gentle, firm pressure with a clean cloth during transport — add more cloth on top rather than removing a soaked one. 

4. Repeated Vomiting or Diarrhea — Especially with Blood 

A single loose stool may not be urgent. Repeated vomiting, bloody vomit, or bloody diarrhea need same-day veterinary care. 

What it might indicate: Parvovirus (especially in unvaccinated puppies), intestinal blockage, pancreatitis, or poisoning. Rapid dehydration from severe vomiting/diarrhea is dangerous, especially for puppies and kittens. 

5. Bloated, Hard, or Distended Abdomen 

A swollen, tight belly — particularly with unproductive retching — is a sign of bloat (GDV) in dogs, especially deep-chested breeds. This is one of the most rapidly fatal conditions in veterinary medicine. 

This is a life-threatening emergency. Do not wait. 

6. Straining to Urinate or Not Urinating at All 

Repeated squatting with little or no urine output can indicate a urinary blockage — particularly dangerous in male cats, where kidneys can begin failing within 24–48 hours. 

This is a medical emergency. Do not wait overnight. 

7. Seizures 

A single brief seizure (under 1–2 minutes) is alarming but not always immediately life-threatening. Multiple seizures within 24 hours, or a seizure lasting longer than 2–3 minutes, is an emergency that can cause brain damage. 

Don’t restrain your pet during a seizure. Keep them clear of furniture edges. Time the seizure and contact your vet immediately afterward. 

8. Eye Injuries or Sudden Vision Changes 

Scratches, cloudiness, discharge, squinting, visible foreign objects, sudden redness, or disorientation/bumping into things (a sign of sudden vision loss) can progress to permanent damage within hours to days. Never attempt to treat eye injuries at home. 

9. Suspected Poisoning or Ingestion of Something Toxic 

Common household culprits include chocolate, grapes and raisins, onions and garlic, xylitol (found in sugar-free gum and some peanut butter), rodent bait, certain houseplants, and human medications. 

Symptoms may include: Vomiting, diarrhea, excessive drooling, tremors, pale or yellow gums, loss of coordination, or sudden collapse. 

If you suspect poisoning, contact Diamond Claw Veterinary Clinic or your nearest emergency vet immediately — don’t wait for symptoms to appear. Bring the packaging or plant with you if possible. 

Note for Sharjah pet owners: unlike some countries, the UAE does not have a dedicated national pet poison hotline. The fastest, safest path is to call your vet clinic or go directly to the nearest emergency veterinary facility. 

10. Extreme Lethargy or Unresponsiveness 

A normally active pet that’s completely uninterested in their surroundings, hard to rouse, confused, or unable to hold their head up is showing a red-flag symptom, especially when paired with any other sign on this list. Trust your instincts — you know your pet. 

Core Vaccines (Required for Every Dog and Cat)

These protect against diseases that are highly contagious, severe, or — in the case of rabies — dangerous to humans as well.

For Dogs:

• Rabies — Legally required; fatal once symptoms appear; protects pets, owners, and the community
• Canine Distemper — Affects the nervous, respiratory, and digestive systems; often fatal
• Canine Parvovirus — Highly contagious; causes severe vomiting and bloody diarrhea
• Canine Adenovirus (Hepatitis) — Causes serious liver damage

For Cats:

• Rabies — Required even for indoor-only cats
• Feline Panleukopenia (Feline Distemper) — Highly contagious and often fatal, especially in kittens
• Feline Herpesvirus & Calicivirus — The leading causes of upper respiratory infections in cats

Non-Core Vaccines (Based on Lifestyle and Risk)

For Dogs: Bordetella (Kennel Cough) for dogs that visit grooming salons, daycare, or dog parks; Canine Influenza for dogs in high-contact settings.

For Cats: Feline Leukemia Virus (FeLV) for cats with outdoor access or contact with other cats.

Your veterinarian at Diamond Claw will assess your pet’s specific lifestyle to recommend which non-core vaccines make sense.

Puppy and Kitten Vaccination Schedule

Young animals are especially vulnerable because their immune systems are still developing. In the UAE, the first rabies vaccination is given no earlier than 12 weeks of age, alongside the standard core vaccine series.

Puppies

Kittens
