Thanks for the good input. It did occur to me that it could be the barrette. It seems today like the hair around there comes out easier... Vet won't see us til Friday. We did very recently treat her with praziquantel because we suspected my sister's dog had tapeworm (they have been playing together a lot) and I'm worried that could have something to do with it. Me being in the medical profession I always think of the million possibilities but vet medicine is different from people medicine! Anyone have something similar to the pic?
