Yestarday morning I found my 10 year old French trotter mare walking in small circles. She walked ok on a lead rope but once in the stable it became clear she could not balance, her head was turned to the right and she gradually leaned to the left then moved sideways to the left. She was wet all over her right side from lying in the wet grass and had a rash over her right shoulder. She showed no signs of pain and was very calm.
My vet was baffled and called out a horse specialist, meanwhile he gave her a small cortisone injection to relieve possible swelling in her brain.
When the second vet arrived just over 1 hour later she was fine and there has been no recurrence. We have no idea what the problem was, any ideas?
Vet thought maybe she had hit her head but no tenderness anywhere, or possibly a small stroke.
Nothing toxic in her field and no contact with other horses recently or signs of her struggling anywhere.
