it is actually possible for an animal to o/d on weed, my mate made a bowl up of around 1/4lb of various weeds (this was about 13 years ago), he left it in his windowsill because it was all too sticky to smoke fackin up the skins everytime he tried to roll one hehe. anyways the not so funny part is he lost his 3 week old kitten. couldnt find it anywhere till he went and cheked on his weed and found the kitten dead on his windowsill and no weed left. (sad story but just so you all know it's possible) granted i doubt a dog could die from it, even a puppy, theyre massive compared to tiny kittens.

stranger things have happened i guess.

the cat i had when i was living in leeds (smudge, i had to leave him there cos my ex wouldnt let me take him...grrr), used to have a bud every time i had a spliff, he'd go nuts for it, rolling around like he was catgasming over some catnip. gotta love the hippy cats!
