My 10 yr old Golden Retriever, Frankie, has a medium-sized cyst (of some sort) on her tail. It's located in the lower part of her tail, and is covered by her tail hair. It's a pinkish color at the top part and has a smaller darker color at the bottom of the cyst. Anyone else come across a similar like cyst on their pet's tail, and any idea what kind of cyst it might be? I'm short on money right now, so I'm not sure about taking her to the vet's office for fear of a costly bill, if it's not a serious health issue. She hasn't messed with it, and it doesn't appear to be secreting anything. Any advise or information would be greatly appreciated.
