My 7 year old choc lab has the same issues. He has a rather large one on his knee that bothers me more than him I think. I was told it is fatty tissue and the vet and I are monitoring them. I was quoted $200 and he was going to do the others at the same time as well, without too much extra costs. However, my dog has been a patient his whole life, and my cat previously, so maybe we got a better rate. I am not sure if it is the same condition either. My dog also had a mole on his eyelid removed that I felt obstructed his vision, and it cost $200 too. The thing is that the anestetics costs about that much for a hundred pound dog, so that's just the min. We absolutely love our vet and our dog and always want to make sure he is healthy. It bugs me that he has this lump on his leg because he is so hansome otherwise, but I try not to be too vain, especially when it comes to my dog. If I had the extra money, I would do it I think, but I don't right now. So unless the vet says it is necessary, it will wait. It sound like maybe the one under his tail sould be removed in your case. We are in N Fort Worth/Keller, so probably too far, but our vet is Dr Arend ###-###-####
