@BarbieQPickle,
Sue them.
You still have time and you will only be able to collect for the "property" value of a dog, but you will make your point.
Chances are you won't find a lawyer who will take your case, but unless your dog somehow produced an income for you, you're only looking at a recovery of $1,000 max, and therefore you may be able to sue them in Small Claims Court and you don't need a lawyer there.
My dog suffered from kidney disease and towards the end I was injecting a med bag of glucose under his skin every night. Our vet told us that to keep him calm when I stuck the needle in his skin I should feed him grapes. He would like them and they were filled with the water he needed. So I fed him grapes and injected him, and within two months or so we had to put him down.
The Vet was wonderful and sent us a beautiful sympathy card.
Not too long afterwards, I learned that grapes are fatal poison for dogs. By feeding him grapes every night I shortened his life!
He was truly sick and wasn't going to get better, but by giving him grapes we hastened his death.
This realization still kills me, but he's gone. I think of him often and I miss him but before we die, a fair number of our loved ones will. Nothing is gained by dwelling on it.
In all likelihood, a healthy Logan would be dead from old age by now. I missed a few years with him, but the same thing could have happened if he darted into
traffic.
These are the things that happen in life. You live with them.
