Even well-loved dogs can develop preventable health problems. In Canada, our shifting seasons, ticks, and long winters add a few extra risks. Here are the most common dog health issues—and practical steps you can take to keep your pup healthier year-round.

1) The most common dog health issues

  • Dental disease: Bad breath, red gums, tartar, and painful chewing can lead to infections that affect the heart and kidneys.
  • Obesity: Extra weight strains joints, worsens arthritis, and increases diabetes risk.
  • Skin and ear infections: Often linked to allergies, moisture (especially after swims), or parasites.
  • Parasites: Fleas, ticks, intestinal worms, and heartworm can cause serious illness. Tick exposure is common in many regions, including Ontario, Québec, and the Maritimes.
  • Arthritis and joint issues: Common in large breeds and seniors; winter cold can make stiffness worse.

2) Prevention: simple habits that work

  • Brush teeth 3–7x/week with dog toothpaste; add dental chews approved by your vet and book annual dental checks.
  • Manage weight: Measure meals, limit treats to under 10% of daily calories, and aim for two brisk walks daily (adjust for breed/age).
  • Protect against parasites: Use vet-recommended flea/tick prevention during risk months (often spring to fall, sometimes year-round). Check fur after hikes and remove ticks promptly.
  • Keep ears and skin dry: Dry ears after swimming/baths; ask your vet about ear cleaners if your dog gets recurring infections.
  • Vaccines and routine exams: Follow your clinic’s schedule for core vaccines (including rabies, required in many areas) and yearly wellness visits—more often for seniors.
  • Winter care: Wipe paws after walks to remove salt/ice melt, use booties if needed, and watch for cracked pads.

Conclusion

Most dog health issues are easier—and cheaper—to prevent than to treat. Build a routine around dental care, weight control, parasite prevention, and regular veterinary checkups to keep your dog thriving through every Canadian season.
