My dog is one of those ccrraaaazzzzyyyy border collies – she lives life hard out (particularly on agility courses) but that does cause problems. I bought this book for the stretches etc to assist her in maintaining mobility as she is still young and 'cause it's great just watching her fly enjoying herself. I've never done this type of body work with my dog before, but it is clearly written and with good illustrations/photos. The stretches work and she loves the massage that I give her through stretching and rubbing – so much so that at night, she carries the book to me so that I can work with it close by.
