The worst thing I've seen Mojo eat was aluninum foil.. and that had me in wide awake fear the entire night.
The worst things my ex-ACD mix ate included plastic baggies of pot, a tooth brush, and clothing. I think the pot was what really messed him up the most. Forget sandwich baggies! Do not let your dogs eat marijuana!
And then there was tilor who basically attempted to eat a pine tree in one sitting. It had been our christmas tree, and after we denuded it of bulbs, balls, and tinsel we threw it out... Tilor who was a labxshepherd mix thought that was the best christmas gift ever! Well, that and the parakeets...
