Oh My sweetie I would never give one of my dogs our pain killers. Please wait, maybe give glucosomine from over the counter for now at Wal Marts. That is best for any injury, HD, whatever. I would be scared to death to give any mg of human pain killers to my big beasts here. I have joint Guard I give them daily to promote healthy hips, joints, ligaments, etc. I get it from www.springtimeinc.com/live and I use the Bug Off rather than Chemicals for fleas n ticks, we are flea free here because of the Garlic and in healthy condition because of the Joint Herbal wafers.
