Doping the dog
When Kurt picked up the "dead" Toby the dog, that dog was knocked out, tongue dangling, good night. While I'm sure it does no harm to the animal, I'm surprised the Humane Association allowed that, but it was a different time then. I'm pretty sure it's not done nowadays, at least I can't think of an instance I've seen on screen in the last 25 years at least.
