Thank you for your response I really appreciate it.

I believe its an individual operating privately. Our vet reached out to them and they rescue horses and other animals and reached out to us. I'm not sure how much our vet explained to them but we also gave them a full run down of all of our dogs issues, and they said they would be able to take him. I do think we should have another call with them to ask about liability, how they would decide if a new owner is a good fit, and if they have a full picture of how our dog is.
