I bought Leo a new chew toy yesterday. This is a piece of deer antler. I have been reading about this product available for sale (at huge inflated prices) and I came across one at a show trade stand (The Doggy Snack Shack!) and decided to try one. He loves it! Hard enough not to splinter or break off, despite much trying! and natural enough to keep him interested for long periods of time. 24hours later, still chewing and hardly a mark on it.Chewing is a necessary part of a healthy dog's daily activity. Chewing is immensely enjoyable for a dog, it produces happy and relaxing feelings for a dog. Chewing enables a stressed dog to calm down. Very often a dog that is stressed or anxious will chew something to try to calm itself down. Best you provide them with something chewable rather than them choosing something from inside your house that they think looks interesting and chewable!
