Lost Pet: Chicken Nugget

Circumstances

an acquaintance was boarding my dog. he was attempting to breed him with another bull terrier. a series of events ensued and this person whom I trusted with my pup, acquired a cane corso that attacked Nugget. This person refused to contact me, was unreachable, wouldn't return my dog and he and girlfriend then GAVE my dog to someone without my permission. they now refuse to tell me where he is or who he gave him to. I have been searching for him since.
