Spring: Allergies, Parasites, and Garden Hazards
Spring brings blooming plants that trigger seasonal allergies in many pets. Watch for itching, sneezing, watery eyes, and skin irritation. Your veterinarian can recommend antihistamines or other treatments to manage spring allergies effectively.
This is also when ticks and fleas become active. Begin or resume parasite prevention as soon as temperatures consistently stay above 4°C. Spring gardens pose hazards: many common plants (lilies for cats, tulip bulbs, daffodils) are toxic to pets, and fertilizers, pesticides, and cocoa mulch can cause poisoning. Keep pets away from treated lawns for 24–48 hours after chemical application.
Summer: Heat, Water Safety, and Outdoor Adventures
Heatstroke is a serious summer risk. Dogs don't sweat effectively — they cool primarily through panting, which becomes insufficient at high temperatures. Limit exercise to early morning and late evening, always provide shade and water, and never leave pets in vehicles. Pavement temperature checks: if you can't hold the back of your hand on the surface for 5 seconds, it's too hot for paw pads.
Water safety is essential for dogs that swim. Not all dogs are natural swimmers — introduce water gradually and always supervise. Blue-green algae blooms in Canadian lakes and ponds are toxic and can be fatal within hours of exposure. If water appears green, slimy, or has a paint-like film, keep your dog out. Rinse your dog with fresh water after swimming in any natural body of water.
Fall: Antifreeze, Wildlife, and Shorter Days
Antifreeze (ethylene glycol) is one of the most dangerous substances for pets, and fall is when cars are most likely to leak or have coolant changed. Even small amounts are lethal — and its sweet taste attracts pets. Clean up spills immediately and switch to pet-safe propylene glycol-based antifreeze.
Fall is peak activity season for urban wildlife. Porcupine encounters send thousands of Canadian dogs to emergency clinics each autumn. Skunk spray, while not medically dangerous, requires immediate treatment with a hydrogen peroxide and baking soda solution (not tomato juice). As days shorten, use reflective collars, LED collar lights, and reflective leashes for visibility during dark walks.
Winter: Cold, Ice, and Holiday Hazards
Canada's winters pose multiple hazards. Frostbite can occur on ears, tails, and paw pads at temperatures below -15°C. Limit outdoor time for short-coated, small, and senior pets. Watch for signs of hypothermia: shivering, lethargy, and seeking warm spots. Road salt causes chemical burns on paw pads and illness if ingested during grooming — wash paws after every walk.
Holiday season brings additional dangers: chocolate, alcohol, xylitol in sugar-free treats, poinsettias, tinsel (a common cause of intestinal blockage in cats), and electrical cords for holiday lights. Gift wrap ribbons are especially dangerous for cats who may ingest them. Keep holiday plants, decorations, and foods out of pet reach, and ensure Christmas trees are securely anchored to prevent toppling by curious cats.
