My wife's dachshund got into her stash, well before we ever met. My wife came home from work one night, and the pup was laying on the floor, barely breathing. She picked her up and took her to the e-vet.
After about 20 minutes, the e-vet came out and asked, "Ma'am, we're really not trying to get you into any trouble, but we're curious if it's possible that your pup got into marijuana?"
My wife, a light coming on in that moment, admitted that it was more than likely that's what happened, and the little buds in between the doxie's teeth were a dead giveaway. They gave her some IV fluids and sent her on her way with orders to let her "sleep it off."
When my wife got home, she'd noticed that the doxie got up on the couch, crawled over to the coffee table, opened her stash box, and had helped herself to the pot. There was about 1/8th oz. missing, she surmised. The doxie is still alive and kicking today at 14 years young and doesn't miss a beat when it comes to meal times.
If they got into the Raisin-Onion Pot Brownies, that would really be bad.
