We just got back from a ride about 15 min ago, when coming up the driveway my husbands horse started breathing rapidly, nostrils flared out. My husband walked him, but he is still doing the same thing. He is not sweaty, we did not work the horses hard and only walked the last 1/2 hour home.
He did drop his manhood at the trailer when untacking and smacked himself on the belly a few times, then dropped himself again after 15 min walking.
My husband did let him take a couple swallows of water a few minutes ago.
He is till breathing rapidly, nostrils flared, his veins are popped out on his legs and chest, no sweating. All I can think of is choke, but didn't eat anything on the trail, and is not drewling...
Any help here? Should I call the vet asap?
