MY dog ate my herb stash Animal Cruelty?

Ok so about last week my 1 year old german shepherd decided to eat my stash he ate about 9 grams of just stright herb and was trippin out. when i got home he was acting weird so i got scared until i found my empty zip lock bag. So i put him on the couch made hhim comfertable petted him and turned on animal planet dogs 101 it seemed to me like he had one hell of a high.So when i reuped on some more herb i was rolling a j and he jumped on my bed seen the ganja and tried to eat it up so clearly he loves weed just as much as me so i blew smoke at him and he wast opposed to it just sat on my lap sniffing up the smoke.My question is should i give him edibles like cookies and such or let him eat the weed or should i blow smoke at him does it make a difference for dogs is smoke better or him eating it up.and how many people think this is animal cruelty when he wants it noone is forcing him he would leave if he didnt want it dogs dont fall under peer pressure. this is the seconed time he tried to eat my stash the first may have been on accident but the second he wanted it.
