This looks like a touchy subject for some, but I'm game to relate some stories.
With respect to PuGGz post:
You've given me the incentive to do some serious research on this PuGGz. I've never considered the implications of cannabinoids on animal health and wellbeing.
On to the anecdotal tales.
The first stoner dog I ever saw was a small fox Terrier. His owner had his bedroom under his house and that was his smoking room. He would always close the door "because my fucking dog keeps hassling me for shotguns". It was true! I was in his room one arvo and he mulled up. As soon as the first cone was pulled there was whining and whimpering and scratching at the door. I got him to open the door and this dog raced in and leapt at the couch. He sat between me and my mate and for four cones got up real close to our faces and lapped at the exhaled smoke.
Then he settled for a bit, then started chasing imaginary cats (I figure) around the room, then lay down and went to sleep. The weed had never been forced on him. Apparently when he was a pup he used to be in the same room when this guy smoked and took a liking to it. The real proof of this dogs liking for a bit of hooter was the scratch marks on the bottom of the door.
I saw a dog turn from a partway intelligent dog to a brainless mutt (permanently) after eating a bowl of Gold Tops that someone had left on the floor of a room one day. We found him lying on the floor (a big White Bully/Dane X) and it took ages to get some sort of attention from him. After that day the dog slowed right down. Lost all his 'spirit' and just wandered about his owners place in a half daze. Not nice, but not something that his owner forced on him. It was an unfortunate accident. I heard that years later he started going schizoid at cats and had to be put down after killing four or five around his neighbourhood (the dog, not the owner).
My dog will sometimes come up to us and make a 'choof' sound when we're smoking. That's when we know he wants a shottie. He will usually hang around for one or two and then wander off and chill for a while. Sometimes he doesn't bother. I wish I could say no sometimes when there was weed around. That'd be different!\
I'll definitely be checking this out further, because I don't like the idea of giving my dog a lung problem like bronchitis or whatever...or some psychological disorder. Does being a really, really good puppy count as a disorder in dogs?
(That was a rhetorical question).
