Our yorkie first starting ripping the stuffing out of every soft toy we gave him. So we tried those tough toys and he found a way to get holes through those and eat insides of those. Yesterday I bought a rubber ring thinking there was no way he would ruin that, and he started to bite off pieces of rubber and ate them.
He is not like this with anything else in the house, only his toys. How can we get him to just play with his toys, not destroy them?
