Common Dog Health Issues (and Why They Happen)

Most dog health problems are preventable with a few consistent habits. Canadian dog owners also face seasonal risks—icy sidewalks, road salt, and ticks expanding their range. Knowing the most common issues helps you act early and keep vet bills down.

Dental disease: Plaque leads to gum infection, pain, and even heart/kidney strain.
Obesity: Extra weight worsens arthritis, diabetes risk, and breathing problems.
Ear infections: Common in floppy-eared dogs; triggered by moisture, yeast, or allergies.
Skin allergies/hot spots: Can flare from food, pollen, fleas, or winter dryness.
Parasites (fleas/ticks/worms): Ticks can transmit Lyme disease in many Canadian regions.
Upset stomach: Often from scavenging, sudden diet changes, or rich treats.

Prevention: Practical Habits That Work

Book routine vet care (at least annually; more for seniors). Ask about region-specific parasite protection and core vaccines based on your dog’s lifestyle (city parks vs. cottage trails).

Brush teeth 3–7x/week with dog toothpaste; add vet-approved dental chews.
Measure meals with a cup/scale; limit treats to <10% of daily calories.
Daily movement: two brisk walks plus short play/training sessions beat “weekend warrior” exercise.
Tick checks after hikes; focus on ears, armpits, groin, and between toes.
Ear care: dry ears after swims/baths; use a vet-recommended cleaner if prone to infections.
Winter paw protection: rinse off salt, trim paw hair, and use booties or pet-safe balm.
Slow diet changes over 7–10 days; keep garbage and compost secured.

When to Call Your Vet

Seek advice fast for vomiting/diarrhea lasting >24 hours, sudden lethargy, laboured breathing, suspected toxin exposure (including xylitol), or intense itching with broken skin.

Bottom line: Consistent dental care, weight control, parasite prevention, and seasonal protection are the biggest levers for lifelong dog health—especially in Canada’s changing climates.
