I recently acquired an 11 year old TB who tosses his head badly. I took him to be floated yesterday and the vet told me his mouth was a wreck. I can't wait to see if this will make a difference. Dr. Told me his mouth was so bad that I should wait a week to bit him up because he'll be so sore and he will basically have to learn how to chew again. YOU NEVER KNOW what's going on in their heads or mouths if you haven't owned them since birth!!!
