My Dog Is Losing Hair On Neck And Has Small Red Bumps Too? Who Can Tell Me Any Ideas On Cause?

My dog has a little red spot on its neck and it doesnt have hair on it. Why?

It can not be told what actually your dog is having without physical examination because many conditions can cause hair loss and bumps on the neck of your dog. These are allergy to flea, pollens, molds, and foods, scabies,  Cheyletiella or lice , pyoderma, ringworm infection, Cushing's disease, endocrine diseases, autoimmune skin diseases and almost all skin diseases.

Hair loss in dogs can be due to some underlying cause, so, it should not be ignored and visit to vet is necessary.

My dog is losing hair on his neck has one red bump? Hes 15 and on tussigon for cough and pain. This is new he never lost hair before he is allegic to fleas, has been for 13 years.

I am thinking that maybe your dog has atopic dermatitis or atopy
