What is it about?

Mouth lesions were very common in trotting horses. Of all the horses 84% had lesions and 20% of the lesions were graded as severe after a race. Blood was visible outside the mouth in 2% of the horses, but additionally 10% of the horses had blood on the bit or inside the mouth.

Why is it important?

Lesions in the mouth cause pain and compromise equine welfare. The majority of lesions do not bleed outside the mouth. So lesions are easily unnoticed.


I hope this article increases the avereness of this horse welfare problem. Writing this article was important since there is not many studies about horse welfare in harness racing.
