Excerpt from Play With Your Dog by Pat Miller
Your best option for finding compatible playmates for your dog is to identify your dogโs play style and select dogs of similar size, energy level, and play style preference.
Size matters. No doubt there are dogs of significant size disparity who can play well together, but as a general rule, itโs wise to keep the difference in the realm of 25 pounds or less. A playful dog can easily injure a little dog, even without intent to do harm, simply by running over or jumping on the smaller dog. Of even greater concern is a phenomenon known as predatory drift in which something from a dogโs evolutionary past triggers the larger dogโs brain to perceive the smaller dog as a prey object โ a bunny or squirrel โ instead of the canine pal heโs played happily with for months or years. Often the trigger is the smaller dog running, yelping, or squealing. The bigger dog gives chase, and tragedy ensues.
To avoid this, good dog parks offerโand enforceโseparate play areas for smaller dogs, and wise owners of small dogs donโt allow them to romp with canines who are considerably larger. Owners of big dogs sometimes mock owners of toy breeds for their โoverprotectiveness,โ but the risk is very real. There are plenty of examples of small dogs, especially tough small dogs (Jack Russells come to mind) who routinely hold their own with larger playmates, and lots of tiny dogs live long and happy lives with much larger dogs.
My own 8-pound Pomeranian shared his life unscathed with dogs in our family as much as ten times his sizeโalthough Dusty didnโt really play with his large siblings; it was more like a peaceful coexistence. If youโre actively lookingfor playmates for your dog, however, itโs safest to keep size cautions in mind, as well as play styles.
