Common Dog Health Issues (and How to Prevent Them)

Most dog health problems are easier (and cheaper) to prevent than to treat. In Canada, where seasons swing from icy winters to hot, humid summers, staying ahead of common issues can keep your dog comfortable year-round and reduce surprise vet visits.

Top Health Issues to Watch For

Dental disease: Bad breath, red gums, tartar buildup. It can lead to pain and heart or kidney stress.
Obesity: Extra weight worsens arthritis, diabetes, and breathing problems.
Skin and allergy flare-ups: Itchy paws, ear infections, hot spots—often worse during spring/summer or with indoor dryness in winter.
Parasites: Fleas, ticks, and intestinal worms. Ticks are a growing concern in many provinces, including Ontario, Quebec, and Nova Scotia.
Joint issues: Arthritis and mobility decline, especially in large breeds and seniors.
Stomach upsets: Vomiting/diarrhea from diet changes, garbage-eating, or rich treats.

Prevention Checklist (Simple Habits That Work)

Book routine vet care: Annual exams (twice yearly for seniors) and keep vaccines current based on your region and lifestyle.
Protect teeth: Brush 3–5x/week with dog toothpaste; add VOHC-approved dental chews; schedule professional cleanings as advised.
Manage weight: Measure meals, limit treats to 10% of daily calories, and aim for daily walks plus play. Ask your vet about a healthy target weight.
Use parasite prevention: Talk to your vet about tick/flea and deworming plans—especially if you hike, camp, or visit dog parks.
Support joints: Keep nails trimmed, use ramps for cars/stairs, and consider vet-approved omega-3s or joint supplements.
Feed smart: Transition foods over 7–10 days, avoid fatty scraps, and keep toxins (xylitol, grapes/raisins, cannabis edibles) locked away.

Bottom line: Consistent routines—dentistry, weight control, parasite protection, and seasonal awareness—prevent many common dog health issues. If symptoms persist more than 24 hours or your dog seems painful or lethargic, contact your veterinarian promptly.
