Poor little Lily! I'm so sorry to hear this Robin! I do hope that she won't require sirjury! I've never had a senior pup undergo surgery. But the complications of surgery for older dogs are similar to those in humans, especially respiratory and cardiac complications. But I've known of many seniors pups who have done great. Lea's vet of course would do a full workup, xrays and blood work prior to and discuss any possible complications with her. Is Lily otherwise healthy? She sure is a cutie! Lots and LOTS of positive thoughts and prayers for Lily and family!
