I had a Jack Russell and he would chew these cloth bones until I wised up to stop giving them to him.(he really liked them) Then one day I see him laying in the yard like he was dead with his feet looking funny. I walked out in the yard and there are strings of cloth hanging from his rear after a couple of days chewing on it. I didn't figure out what it was right away. Nasty
So that was the first time i had to pull you know what out of my dogs you know what. It was stuck and he just laid down until i saw him

Working at a recycling center. People don't really respect the "Cardboard Only" sign. You'd find anything from a dead animal to used condoms and tampons.
