Prepare for unexpected vet bills
If your dog has special needs, or just really likes to swim, then Water4Dogs is the place to go. You get to bond with your dog, play toy retrieval (fetch) in the pool, and socialize with other dogs.
If you're looking to train your dog, but would appreciate the extra help, check out School for Dogs. Canines get socialized with other dogs, take behavioral classes, and even get specialized NYC sidewalk training so they don't try to sniff or bother other New Yorkers.
