hi,my 6 year old med/large cross dog has a lump on the top of her tail about half way between the tip of her tail and her back end. it is about the same size as a small marble, its is hard and the same colour of her skin. it does not move. it does not bother her when you touch it, and she is acting her usual happy self eg feeding, walking, playing.

last week a found a small lump under her nipple(the size of half a pea) and took her straight to the vets, the vet told me the lump was nothing to be worried about,useless it tripled in size. she already has one on her neck (size of a marble) the vet also said this was noting.

i was just wondering if anyone knows what this is,i will ring my vet first thing and see what he says but would like to know if anyone could help me until then.

thanks alot Nicola and phoebe dog
