I recently received an email from a lady with a question about a tongue issue that her horse had all his life. His tongue often comes out of the front of his mouth, c. 4cm, and goes back in, almost like a snake’s. It sounds like a licking motion. He has a tendency to worry and to get distracted.
Since I don’t know the rider or the horse my advice had to be relatively general, suggesting several possible causes for this phenomenon that she can investigate on her own. And then I thought that this might be an interesting topic for others as well because mouth and tongue issues are not uncommon, and they can be caused by a variety of factors.
