Why Is My Dog Scratching So Much

Should I go to the emergency vet?

Go the same day if the face is swelling, the dog is scratching until the skin bleeds, or a new flea product was applied and the dog is tremoring or drooling. Chronic scratching can be scheduled this week.

How much will treatment cost?

The visit looks for fleas, a skin infection, and mites. Cytology and a scraping are the usual tests. A food trial or allergy medication is a follow-up cost. Ask what the first visit will test before you buy another shampoo.

Can I treat this at home?

Use the flea control the clinic already recommended, wash bedding, and stop new essential oils or human creams. A cone prevents a hot spot from expanding overnight. Oatmeal shampoo does not kill fleas or mites.
