Itchy skin, recurring ear infections, or constant licking can be more than “just a habit.” Dog allergies are common in Canada year-round, and early action can prevent chronic discomfort and costly vet visits. Here’s how to spot the signs, understand the causes, and choose effective treatments.
Dog Allergy Symptoms: What to Watch For
Allergies often show up on the skin and ears—not just as sneezing. Contact your vet if symptoms persist longer than a week or keep returning.
- Itching, rubbing face on carpets, chewing paws
- Red skin, hives, hot spots, hair loss
- Ear issues: odor, head shaking, recurrent infections
- Digestive signs: vomiting, diarrhea, gas (more common with food allergies)
- Watery eyes or mild sneezing (less common than in people)
Common Causes in Canada
Most dogs have environmental or flea allergies; true food allergies are less common.
- Environmental (atopy): pollen (spring/summer), ragweed (late summer/fall), dust mites (year-round), molds (often worse in damp seasons)
- Flea allergy dermatitis: a single bite can trigger intense itching
- Food allergies: usually proteins (chicken, beef, dairy) or occasionally grains
- Contact irritation: de-icing salts, some shampoos, grasses
Treatments & Practical Next Steps
Start with targeted prevention, then work with your vet on a plan.
- Book a vet exam to rule out mites, infection, and secondary yeast/bacterial issues.
- Use prescription flea prevention consistently—especially in multi-pet homes.
- Wipe paws and belly after walks; in winter, rinse off road salt and use dog booties or paw balm.
- Bathe strategically with vet-recommended hypoallergenic or medicated shampoo (don’t over-bathe).
- Try an elimination diet for 8–12 weeks (vet-guided; no treats/flavoured meds).
- Vet treatments may include antihistamines, omega-3s, Apoquel, Cytopoint, ear meds, or allergen immunotherapy.
Bottom line: Dog allergies are manageable with the right diagnosis and consistent routine. If your dog is itchy or getting repeat ear infections, prompt vet guidance can bring fast relief—and help prevent long-term skin damage.
