My dog has arthritis as i have said before. I have been researching and I have found that heat is good to loosen up the joints. Anyone have success with his. Im not sure how else to help him. I have him a nice bed, but he dont lay on his bed much he likes the kitchen floor where is cooler. Will a heating pad over heat him and if I can use it how long should I keep it on him 10-15 minutes?
