But first, let's caveat the term "indestructible." According to one of our testers, who has a Cavalier King Charles, "every indestructible dog toy is completely destructible, for the record." A persistent dog can, eventually, get through anything — and large breeds like labs and pit bulls can chew through stuff faster than most. We regularly test pet products to recommend only the best ones that keep your mischief maker out of trouble. In finding the best "indestructible" dog toys, our product experts sifted through countless five-star options, spoke with owners of large and small dogs and looked at some toys in our Lab as well. The best toys replicate natural behavior," says Gary Weitzman, DVM, MPH, CAWA, author of Complete Guide to Pet Health, Behavior, and Happiness."Enrichment toys and play are essentially substitutes for the survival skills dogs were born to develop." The right toy for your pooch can keep them happy and stimulate their brain, so we're happy to help you invest in toys that actually last longer than most. Companies suggest replacing a dog's toy once there are signs of medium wear, to avoid the toy becoming shreds that get swallowed.
