i have noticed tegan blowing out quite quickly over the last month and recognised the signs for lungworm so i treated her immideately and gave her a bit of a rest she had also knocked her wrist up on a bad tumble she took so a rest was needed all round .... anyway after a bit of a let up i started running her and again she was starting to blow out early ... now the only other thing i could think of was an internal injury after the collision with a tree stump (the same one that damaged her wrist) a diaphgram or rib injury that was causing the problem and i really wanted to get her to a vet that
