Oh gosh I'm so so sorry for your that you all had to go through that and lose the little guy. . I dont know if you have any recourse against Petland or not but if it was me I'd be writing their corporate office. You can find their main corporate contacts usually by a google search. They may even have corporate counsel. While I'm not an attorney I do work for a few of them and I've had to do this type of searches many times. Did your BF take him for a vet check after he got him? I ask because that's required by most breeders. Again, I am so sorry for your loss!
