如果你有一个嚼,你知道很多狗玩具可以在几分钟内被破坏。市场上一些产品声称自己是“坚不可摧的。”They are made from solid rubber, like the kind of material used in tires. They are heavy-duty and meant to be hard for dogs to chew through. While really heavy chewers can eventually gnaw through and break a lot of these "indestructible" toys, the tough versions of balls and other shapes do tend to fare better with rough play than other dog toys. Features to look for include shape, which is often a ball or a tug-pull shape. Sizes should come in those appropriate for either large or small dogs. The hole in some of the toys is meant to be a safety feature to prevent choking. Choosing a bright colored toy will make it easier to see when you are playing fetch.
