I have a middle aged cocker spaniel, he has days when he seems slower than others, like he is in pain or maybe just achy. I give him a massage with my fingertips all over. leg joints, sides, belly, neck, and such and he seems to enjoy it and he responds well after I am done. Slow gentle movements with my fingers moving in circles. He moves much better after his massage than he did before. I have also encouraged him to drink small amounts of warm honey water with tumeric. This has been proven as a pain reliever in dogs. About a cup of warm water with a tablespoon of honey and just a pinch of tumeric. I do not particularly like to use drugs, either dog or human pain relievers with him, because each dog has a different response to chemicals dependent on body weight and size. with dogs I have found homeopathic is better.
