i think my 5 month old foal as a contracted tendon on her back right leg. the back of the fetlock feels swollen and i can feel sort of like a vibration in her leg. if you look at her from the back her pastern and fetlock look straight. and from the front it looks bent. I'll be calling the vet in the morning but i was just wondering if thats what it could be. she is on full turn out on pasture that has all sorts of grass. she is still nursing a little and she eats grain with her mom but its just a 16% protein pelleted feed nothing special and she dosent eat much of it. she is already wearing a colt halter (300-500lbs) i tryed to get pics but all i had was my phone and it would show up.
