<p><br />Bertrand had a lump by his butt and the vet said, since he had a first year full of diseases (when we bought him, he was 1,5 years old), she didn't want to take it out just yet. We should just keep an eye to it, since it looked to be only fat. 2 years ago, it grew about 4 times in 15 days, and all the 3 vets we consulted said the same thing, it was probably cancer (even a cancer specialist agreed). We took him to have the operation and we discovered that, thank god, it was only fat tissue. Then, another one appeared over his mouth, this one was drained, it filled up again and was drained again and now is fine. His sister, who lives on the other corner of the street, has loads of them (according to her momslave) and the momslave pushes them to the surface and drains them. It is easier for the dog to have it drained, otherwise it is a surgery, small one but nevertheless, has its threats. However, you should beware of filling up again.<br /><br />Isabel and Bertrand</p>
