How to tell allergies from infection — and what to try first at home.

Itching has three common causes: parasites, allergies, and infection. They often overlap, which is why home guesses miss.

First, rule out fleas — even one or two can trigger weeks of itching in sensitive pets. Use a vet-recommended preventive year-round.

If the skin is red, oozing, or smells yeasty, that's likely an infection on top of an allergy and needs prescription treatment. Don't reach for human creams; many contain ingredients toxic to pets.

For mild seasonal itching, regular baths with a gentle oatmeal shampoo and an omega-3 supplement help many dogs. If symptoms last more than a week, book a visit.
