Many cats and dogs are given bones as treats, but it is not a good idea. Many types of bones, the brittle ones like those from chicken, can get stuck in the esophagus or the intestine, they can rupture the gastrointestinal tract, break their teeth, puncture their mouths and all of them cause constipation. So if you want to give your pet a yummy prize, there are special bone-like treats specially made for your pet.
