Legal Question in Civil Litigation in Georgia

Of course you do not get the police involved in something like this and waste their time and resources. They would probably let you know that very quickly. You also have a problem in that he paid for the dogs, and you have the burden to prove it was a gift to you. From a legal perspective, even if you had a valid case, you would be entitled to the legal value of the dog which is basically the cost of buying a new one. I am ruling out spending thousands of dollars in a Superior Court case to get the dog back. One solution not even mentioned in your post: If the dog is happy and well cared for, and happy being with the other dog as it is now accustomed to, move on and get another dog for yourself. IF this is not really about the dog, move on.

This is obviously not a criminal case so do not call the police.

Georgia generally will not help a gay person verson another gay person in court since the state does not recognize such relationships. Nonetheless, you could try to prove the dog was a gift (not likely proveable based on the facts as you gave them). But if you think the matter is worth thousands in legal fees you could try. It might be far cheaper, and better for the dog, to adopt a stray at the pound.
