Look at this site I came across this morning: Dog Island Free Forever

Over 2,500 dogs are already enjoying a better life at Dog Island. Separated from the anxieties of urban life, dogs on Dog Island are healthy dogs who live a natural, healthy and happy life, free from the stress and hardship associated with daily live among humans. They live with almost limitless space, and tens of thousands of rabbits, rodents, fish and other natural prey. Surrounded by thousands of other dogs, this is the only place for them to be truly social and create healthy families. Dogs at Dog Island have another chance.

and even better, on their FAQ page:

My dog is being picked on by neighborhood raccoons. Can you give me any advice?
Yes. Send your dog to Dog Island. But in the meantime, teach your dog to be tough. Buy a BB Gun and get your dog a stuffed raccoon, like the owners of our favorite dalmation, Charlie, did (see article)

So you give them your dog, they release the dog on some island where the dogs are free….and hunt rabbits all day. Doesn’t this sound like some movie?

If you want to send your dog there on a “3 week vacation”…

Vacation Island: Three Weeks
Vacation Island, on the other hand, is very very expensive. It is only for rich people who have that kind of money to spend. This is the only way to visit the island with a dog and still come back with your dog.
