At least anecdotally, more families than ever have been acquiring dogs. My own experience with this is that my daughter's family have a newly adopted Shih Tzu who has turned out to be a wonderful companion for my two grandchildren. And to my surprise (I think I should know better), this dog loves to play - she retrieves toys, plays tug, and will run with my grandson, especially if he is holding a treat in his hand.
Off-Leash Dog Play by Robin Bennett.
All this is a way of getting around to the subject of playing with your dog which is a great way to build a strong bond, give the dog exercise and to train certain behaviors. This is something that novice dog owners may not realize, but they should check out a new dog's play drive - they, like me, might be pleasantly surprised! Here are some books that might help:
Play Your Way to Good Manners by Kate Naito and Sarah Westcock.
The Best Book of Tricks for the Best Ever Dog by Larry Kay and Chris Perondi.
Play With Your Dog by Pat Miler.
The Magic of Games by Sally Montruchio.
Play Together, Stay Together by Karen London and Patricia McConnell.
And just in case you are getting young kids and dogs together, check out Living With Kids and Dogs - Controlling the Chaos by Colleen Pelar.
