One time long ago my buddies dog ate our puke and tripped with us. Was a phenalthylamine 2C-E or something (more hallucinogenic but weirder analogue of 2c-b) and made us puke while on the trail away from our campsite. Dog snuck back there while we were at the camp fire. He had an absolute riot of a time chasing shadows, pouncing on them then digging holes, and running rings around us for hours
