Sad story.
A friend of a friend of mine "owns" a beautiful lab but overfeeds and underexercises, (never exercises) the dog.
Twice the dog came to stay with us for an extended period of time, and i took a lot of time and care exercising the dog back to homeostastis, (slim, trim, muscular, bright eyes.) Last time she gave custody of the dog to me, only to steal her back, which broke my heart. Now, it's inconvenient for her again, and the dog is with the first friend i mentioned, again. The dog is bigger than ever. Yes. She looks like a walrus, but she is still the awesome and beautiful girl she always was. I've gotten another dog, and poor caregiver's boyfriend has gotten her a puppy. It's all too sad. I go visit and play frisbee with the dog, but I can't get further involved anymore. - unless she puts my custody in writing.
