I dont think humans can really eat that fruit cake without feeling weird...
My dog ate a thrown out pork roast and bone, with onions, and i cant tell you how sick that dog got! we were over at someone elses house whilst moving back to Florida, and he **** all over his kennel in their garage, and then i moved him up to the bedroom we were staying, and same... everywhere all over the floor, so i ran him downstairs again and outside (i could only have one dog in the house at one time- theirs was a pit) he was crapping everywhere out there, and when i thought he was done, i brought him back up there to the room, and started cleaning the mess, when he threw up 1+ gallons of vomit everywhere on their bed. i ripped the sheets off as they sank down to the matress- the smell could peel the paint off the walls. all in all, i cleaned it all up, and never told them the destruction my dog caused at their house. i am terrible.
FYI: onions are poison to dogs. i now know this.
