My 8yr old Sec A childs pony has been losing condition gradually the past few months. A few weeks ago I noticed him quidding on his hay so I called the dentist out. He said his teeth very very sharp and irregular and did quite a lot of work rasping them. Days later he was still quidding which I put down to him maybe being still sore but over a week later he was no better if anything slightly worse. The dentist has returned but can not find anything wrong now which could be causing him to continue to do this???? He advised feeding hard food to try to maintain condtion which im doing and he eats that fine including chaff ! I've tried changing his hay / haylage but he's still doing it ??? Im getting concerned as he's a much loved childs pony and is usually a good doer so any advise is very welcome please ???
