I have had honey for about a week and purchased her from a pet shop (long story, bad idea). They said this pink mark is a bite from a rottwieler on her head but i am curious to weather its a bite or a tumor of some kind at early stages. Please any pictures to differ a regular bite to a tumor at an early stage would be very helpfull. Im planning on going to the vet sometime next week. Please any advice and anything u have to say would be very helpful, shes my first boxer and im in love with her allready. thanks for your help and time....
