My dog ate too much weed!

Oh crap!!! I had made some cannabutter yesterday with an ounce and a half of dank bud in three and a half sticks of butter. I dumped the cheesecloth buttery buds out the back door when I was done. This morning I let the dog out and he found it and ate it all except for the cheesecloth but he'd been chewing on it. He's a 55 lb blue heeler.
Crap he's so stoned he can't even walk. He's spinning around and acting delirious. I sure hope it doesn't kill him.
Oh hell, he just threw up.....
