i am so sorry to hear about your loss,my heart and prayers go out to you .and although i am not familiar with how the law work regarding your situation i do think you should definatly consult a lawyer that specializes in such cases .it definatly sounds like malpractice to me ,unfortunatly there are heart less vets out there i wish you the best of luck ,and if you cant file a suit please do all it takes to prevent this from happening again,in memoryof your precious angel that is now in heaven waiting to reunite with you one day. go public about it maybe if you can get some kind of press involved someone out there might be able to further help you.
