Very, thank you, far more pleasant then...previous posters of different views. My dog never liked the smoke at all so I made him treats, but they were never very strong. I normally made the butter just using swag seeds, and he was only allowed two a day. I was fortunate enough he never wanted my stash. (We did once have to resist killing a neigbors cat for stealing our stash right from under our stoned noses while we sat in the back, didn't see the kitty for a few days, but I KNOW she had to be blown our her wits)
as far as health, now that you mention I guess allergies should have been a concern, I got lucky I suppose, he's still alive and well and 10 years old. Use to also put this stuff called 'Rescue Remedy' in his water bowl, it was several herbal extracts, including passion flower, that helped calm his nerves.
