If your pup is scratching nonstop, you may wonder what causes excessive itching in dogs. While an occasional scratch is normal, constant itching often points to an underlying issue. Common causes include allergies, parasites, infections, and skin conditions. Understanding the root problem is the first step to helping your dog feel comfortable again.
Common Causes of Itching in Dogs

One of the most common dog skin irritation causes is allergies. Dogs can suffer from:
-

-

-
Pollen allergy in dogs and dust mites and dog allergies
These conditions often result in dog licking and biting skin or dog losing hair from itching.

Ticks on dogs → Irritate skin and may transmit disease

Mites in dogs → Lead to mange in dogs, including sarcoptic mange and scabies in dogs
