Wow....I'm super glad I had other things to do this weekend. This thread is an utter train wreck!
To have a rescue foot the bill for this dogs treatment and allow the OP to keep her is quite frankly one of the most ridiculous notions I've ever heard. It shouldn't be the job of some outside entity to foot the vet bill for someone because they can't afford it, which is basically what that would be doing. This dog needs help and is in a home where the owner can't provide it. She needs to be in a home where it can be. Period. Not a difficult concept to grasp. Funny, I explained the situation to my 9 year old just now and she said the same thing. Guess my 9 year old has a better grasp on reality than some of the people who have posted in this thread.
Still wondering about the OPs two Chis...
