I will tell you NEVER to give your dog any rawhide. My puppy was given a rawhide (when I was not home), the kind with knots on both sides, he chewed and ate 1/2 of it, then I came home, shocked to see my pup with a piece of rawhide so I tried to get it away from him but I was too slow, he just swollowed the rest (the not-yet chewed rawhide with one knot). He drank all day, diarrhea day and night and a trip to the vet. I was very worried (never this worried in my life) that he might have a stomach blockage. I slept next to his crate to take him out in the middle of the night. After a few more days he was better and I did not see anything come out with his poo. So until now I don't know where that knotted rawhide is. NO RAWHIDE.
