A session of purposeful play can introduce your dog to novelty and enrichment, like new smells, a variety of new textures, or new toys that can offer him unique and beneficial challenges when they’re not presented in an overwhelming manner. In addition, providing safe access to the sights, sounds and smells of the outdoors may stimulate a dog in a positive way.
Usually play is beneficial although play that’s too aggressive or that lasts for too long can lead to overstimulation. A good tip is to end a play session while your dog is still having a great time. This leaves him excited for his next session, rather than exhausted.
