Need advice on thick legs.
My friend's horse has suddenly gotten 3 of his legs thicker than usually, to say the least - quite swollen.
His diet consists of hay, straw from the bedding, a few lbs of grain mix, some carrots after a workout, enough minerals, salt, everything.
His workout is usually 5-6 days a week dressage - cannot describe the level, as he is work in progress but has shown in A level.
He is 7 yrs old, about 17hh gelding.
He has recently had a cold, he has been diagnosed with kidney problems, which have gotten better with medicine and he has felt very good. He is not lame on any of his legs, he was still energetic today with all the swelling. They are considering the vet tomorrow, if nothing has changed or has gotten worse.
Yesterday he had an easy workout, not much, but sweated.
Today it had gotten warmer a little, he never sweated. As he normally sweats with even a little workout.
He has a box with a paddock, goes to a field every few days now.
Nothing really has changed in his routine or diet, everything is the same. Apparently he had been stuck lying down in his box for a bit, but didn't show any signs that he got hurt because of that.
He does get very good care, I am just curious of what could cause this..
