That’s pretty much the emotional trajectory of a dog during the first 5 minutes upon receiving a new toy. A recent study of dogs and toys showed that most dogs lose interest in toys partially because of the toy isn’t all the interesting in itself, but mostly because they really want a human to help them have fun with it. However, in an assessment of the best types of toys that might hold your dog’s interest for more than a few minutes, they found that chewable and squeaky toys were best along with items like rawhide bones that provide hours of activity. Dogs generally like to gnaw on toys and bones when they’re lying down, so be sure to give them a soft spot to work their jaws.
