I am a bullie owner. My lola is 2.5 years old. She is a great dog!!! But today I noticed a small nickle size area on her lower right side. I thought it was some kind of sticky something since my daughter and nieces and nephews had been playing with her. But as I took a warm wash rag to it I noticed that the hair was gone and there was a sore place. She had been scratching and licking a but more than usual. I think its her allergies because she does have some small welts on her back. We give her zyrtec. Is benadryl better? Or is there a special shampoo I can use. I have been using pet head. Help please!!
