Any dog-owner will know that some toys are a big hit with their pets, while others do not seem to interest them. It is not because they are growing out of puppyhood and losing the desire to play; it is more to do with the fact that they look upon their toys as their wolf ancestors looked on their prey. If it can't be chewed, and it doesn't make a noise, it does not give them much reward. This is why they really like toys that squeak, can be munched up or torn apart, or in the best case scenario, that taste like food. Hidden treats in a rubber kong can keep a hyperactive dog quiet for hours.Toys are important in our dogs' lives as they replace the activities that would have kept them busy in the wild or as a working dog. Tug toys, like rope pulls, are only fun for your dog if you participate. This kind of active toy is ideal for encouraging fitness and vitality. When they have to spend time on their own, chew toys can prevent the boredom that can sometimes lead to destructive behaviour. Chewing is essential throughout a dog's lifetime. As a puppy it helps with teething, and late on it exercises the jaw muscles, is good for the gums, and causes contentment.
