So sorry to hear this.. Hang in there.. These dogs are amazing. My 7YO Black Lab is diabetic (Been on insulin for 2 years) He has lost most of his site in his left eye. Went to the vets for a check up and he was diagnosed with Lymphoma. Been on chemo for about a month and a half. You would never know it though. He is as normal as any dog I know. He goes crazy when I mention the "Walk" word and we will walk for close to 2 miles a day. He loves to have his toys thrown so he can catch them. I think if it were me with all those problems, I'd be in bed whining.
