I have a 5 month old dobie and she is getting this raised bumps on her legs. (or dog elbow) I was told by a friend who has her sister that it was allergies and to try swithching her food and giving her benyldryl. Also to be mindful of infection because her sisters dry skin became infected also. The look like warts but just on her doggie elbows. A few other pups I seen have the same thing. Is it something that will clear up or should I be worried. Also on top of her head she has 2 thin spots of hair on her head. I have noticed it got worse once I changed her food and now I have changed again to see if it will clear up. I will have picture to show soon.
