Thank you everyone for your kind posts,

Candy's breeder called me and says she is picking Candy up next Monday. The bite does not sound like an aggressive attack, but rather the mark of a high drive Belgian. A jogger ran in-between Candy and her new owner and she turned and bit his ankle, hard enough that it did injure him, but probably not an aggressive action on Candy's part. She is highly prey driven and does go after moving objects (and unfortunatly when you are a Belgian, this can mean people too -- too many people get this breed without fully understanding this). The lady has two young children and is concerned Candy may be a bit much for them -- the reason Marla gave Candy to me when she was placed BACK with her was that Candy would chase and nip her children (not in an aggressive way of course). I had started to break her of this behaviour but in the one or two months I had her I obviously couldn't have completely broken her of it. She would try to bite bicycle wheels that went past us, etc. The new owners tried to contact the people that sold Candy to them -- messages, emails, etc, and the people refuse to contact them back. So I am sure my email will be ignored.

I have cooled myself down a bit, am still very angry at the people I gave Candy to, but am not sure of my options.
Since Candy is going back to her breeder, I can very well leave out the part that Candy bit anyone (so the court can not have her destroyed) and go ahead discussing the breach of contract.
What amount we will be given is a hard one -- I think that it is fair we recieve the original purchase price, money for food/other care we provided for the first 5 months we had her and then the next 2 months we had her when she was returned again, and honestly I think they should have to pay more but that would be up to the court.
I am not sure how to go to small claims court. My friend the lawyer is not answering her email atm. If anyone else here knows about this legal stuff, please contact me. I don't even know where to go to do this. She just said I'd have to pay a minimal amount and made it sound like things would take care of themselves. I want to hit these people where it hurts.
