Went out to go see my horses this morning. Found my mares front left swollen and kinda puffy. When I seen it bowed tendon is what first popped into my head. Her feet are a little long and she is needing shoes again. I was riding her yesterday and she tripped I didn't think anything of it, because she just tripped like she does sometimes. I had support boots on her, but I slowed our speed down and she wasn't limping or anything. When I took the boot off I didn't see anything.
Today went out and it was like seen in the pictures. She's barely got a limp she's never been lame before. She does seem a bit sore but she doesn't act lame. Ideas?
