Trust me when I say this......you can't kill a dog from getting him/her high. I got my one dog trashed on honey oil, he was so ripped I kinda felt bad. I pet him, then used an empty pen tube to shoot the oil smoke at him. Thing is, after 2 or 3 times of doing it, he CLEARLY showed signs of liking smoke.....like coming up, sitting in front of me and whining when I'm toking.
THEN.....the day I knew my dog was more of a weed hound than me.......I caught him doing something hilarious.
He would casually walk between the couch and the coffee table. I would be sitting or laying on the couch and he would look at me, look at the pile of roaches or buds on the table, then look at me again....but sneakily out corner of his eyes....so I would do the same thing, all the time with a grin on my face. This would go on for a few minutes.....he'd let out a whimper....one of those long ones that precedes a yawn.
Then he would walk back and forth between the couch and table maybe two or 3 times, then around that time, he would stick his tongue out, and snag whatever goodies were on the table.......
I called it the "walk-by licking". He would take his prize around the corner and enjoy it. This happened MANY times, and almost became "our thing". I miss that dog.
EDIT: SORRY LOL. I should clarify, he died of old age......sounds bad the way I ended it.....lol
