I have been dealing with something and thought what better place to discuss it is on this forum. I am so distraught about this. I have a 8 year old mare. I noticed in 2009 she was nodding her head when at rest, thought it was just coming out of sleep and jerking her head, but then was concerned and called vet and she checked her and said we can float her teeth to see if that helps, and I felt it did initially, however, that was the year few months later we had her boarded out for the year so I never could keep up with it. Now that she is home with me I have been noticing her when she is standing in the barn or paddock resting she is nodding or jerking or head vertically up and down repeatedly. I called the vet and she came out to check her teeth and said there were some points and she floated her teeth and gave her a check up, said her teeth didnt line up with the other teeth at back but it her jaw was fine and it was not causing any problem it was just the way they grew through her life time. However, she is displaying the head shaking more and I find being in the wind it seems to cause it to happen more. It breaks my heart cause I don't know what can be done to help her, she doesn't appear to be in pain and is eating and drinking and playng around with our gelding. I have read alot on headshaking and there are so many suggestions of what can cause it. Does anyone have hands on experience with a horse who has this? Thanks!
