help me save checker

I had some I had some friends come over and someone left brownies out for my 1 year old puppy to find. This morning I found him laying in his vomit and pee completely disoriented and lathargic. Hes currently getting his stomach pumped and a cathater inserted to flush his system. Blood work ia also being run to make sure his liver and kidneys are ok. I can't afford to fix this stupid mistake alone. Swallowing my pride and asking for any help anyone can give me to save my Checker. Please help us.
