I'm not sure about pet watchers but during a recent trip with my dog, I found several options. I boarded my dog at a veterinarian and was able to drop her off at groomers for a bath and brushing. I guess it all depends on how long you need to be apart from your dog. Good luck and have fun!
For dog sitter, I've had good success using Rover
He is allowed just pick up after him. No idea about pet watchers.
