From what you've said, I take it you don't need people to donate money to you, but can you afford regular vet visits? Do you have a dog house/shelter for the dog? Because if you don't have a dog house or shelter, you can get in trouble. A humane officer would generally tell you to get one, or if you have one and it's not sufficient, tell you to get a new one or do something better, if you're otherwise caring properly for the dog. Just something you should be aware of.
