The vet put Joy to sleep yesterday morning after determining she was in major kidney failure. She believed the cause was anti-freeze poisoning which was why she was probably out in the woods in the first place. The vet believed that the former owner gave it to her, but my husband is a little more forgiving and his suspicion was whoever dumped her probably only knew they had a sick puppy and didn't want to deal with it. Either way, our family and Joy paid the price.
I have so many angry and sad thoughts on this, but am too drained to rant.
