My 16yr old Schiperkke was backed over by a neighbor on a cell phone. Dog went to vet and x-rays revealed nothing broken,"Her fat may have saved her life". While that is very funny, after a long recovery, she still has a mass where the tire pinched her butt to the ground.She gets along OK but now has poop sticking to her fur,as her tail is no longer inside her tail flap,(Skips don't have tails).So I deal with that. But a year later?, the flappy large area is still there. The Vet. just says she's fat. But only there? It feels like fluid. Really. I thought it may had been blood as it did shrink an incredible amount, leaving just the stretched skin with something soft inside.I looked up everything, blood-blister, sarcoma, lymphoma, Shes weird looking, but I would love to be as resilient as she is. She is truly that, "Once in a lifetime" dog. I want to help her. Now it seems she has a NEW Lump! Lumps seem to be common, On the back of her neck,LARGE, and soft.Get's big then shrinks a bit. Started as a mass of extra skin, on one side.Now it's full, and a little to her left. Vet say's, "Don't worry, She had a good life".Well niether me or Beary are writing her off yet.I think I will pierce it and see if it drains, Had one dog before with a small lump, and drained it to never return. Maybe Lady Bear will show and amaze me one more time. (16 is CONSERVATIVE!!) She's older than dirt. I love her. Thanks, Ed
