I made my dog a cloth harness to hold up the baseball size tumor on her belly. It pulls and is uncomfortable to walk. You can make a cloth harness with 4 ties that go up around the back of the pet. Tumor larger than a baseball seems cruel to let it grow beyond that. So surgery or put dog down. Unfortunately I had put my baby dog asleep she waa 15 yrs old and the tumor had a sore appear and waa rotting.
