I have a 4 year old retriever mix dog. She loses hair in small clumps in the early summer, but I went out to brush her today and it looks like the hair aon her back on one side has been hacked at badly with scissors. I doubt this has happened because she is in a fence. She doesn't scratch. She seems very healthy. Should I be worried? I thought maybe her hair had come out in clumps and was growing back in raggedly. Should I take her to the vet? I am going on vacation next week and don't want her caretaker to have to take her in.
What do you think?
