I was a little disappointed. I do not feel that the doctor listened to what was going on with my dog. I tried to tell her that I had treated all of my dogs with monthly flea medication, but, she insisted that I should go ahead and put the Seresto collars on all of my pets right away. Also, I tried to tell her that my dog had some places on her head and her back that I thought were dog bites from my other dog. And, that I had given her a bath with some skin soothing shampoo which turned her skin bright red with a reaction to it. Therefore, she did not know that I needed something for the area that was still bothering her?? A large part of why I brought my dog in.
