I just had my preggo mare Tali's teeth floated yesterday ironically and I've always been suspicious of mishandling/treatment in the past. First, the vet agreed that the way she was acting she was extremely scared but also very level headed about it. She WANTED to be good which in a way made me sad since she's such a good girl and has been abused. ANYWAY, I don't have much history on the mare and when we opened her mouth it was a mess!! Her teeth had so many hooks and jagged pieces that they were digging into her cheeks. My vet says she probably has NEVER had her teeth floated in her 11 yrs of life. My poor poor girl I feel even more responsible for her and she will never be in another person's home again.
