One of my dogs (Pac) injured himself by trying to get over a 6ft. Fence. I believe he pulled a muscle and that's when I found out the value of massages for dogs.
I put two doggy aspirins in a hot dog and gave it to him and massaged his hind leg. I saw how much he was enjoying the massage and since then I give both of my dogs massages after a long walk. They love massages.
