I have taken both the female and the male to the vet to catch up on shots, get additional flea and heartworm prevention, and get checked. The vet said these were common in dogs getting older and that there is nothing they typically do. The lumps aren't around her female organs and there are no symptoms of cancer yet so they said not to worry about it until there are "possible" signs, then they could do a biopsy to find out for sure. These lumps are a little smaller than the size of lemons but there are several of them- around her sides and lower back. She is 11yo. What can I expect with this, just so I can prepare myself and difficult child? Is this probably cancer or signs that tumors are going to quickly take over her body? I first noticed something a few months ago but thought it was just a full stomach because I could only feel it intermittently, depending on the position she was in. Now, there are 3-4 and bigger. How much time will she have?
