Why is my dog chewing on his back?

Answer by  amber33 (1941)

The first thing that I think of when I see a dog chewing on themselves anywhere is fleas. You may not realize that you have them and they can be hard to spot on animals but it sounds like that is what your dog might have. I would get some medicine because your dog will eat at himself up.

Usually the main reason for this is he has fleas. He could also just be bored and looking for something to do. Or he can have a skin condition.

Your dog most likely has fleas. I would purchase a flea dip from your local pet supply store and treat your dog. Afterwards, put a flea collar on him/her.

My dog had this condition a year ago. I contacted my vet and he told me it was fleas, however I checked and he was clean. Turns out skin allergy.

The most common reason a dog chews on his back is fleas. Dogs skin can be very sensitive. It might be the environment, a parasite, nutrition, allergy, neurogenic dermatitis or some type of infection. It is best to see the vet for a proper diagnosis.

Likely the dog has fleas or a skin rash. If there is no sign of fleas, try a medicated shampoo for sensitive skin. If no result, see a vet.
