Some are easier to worm with paste than others.
I had one horse I would have to twitch to worm...took 2 of us.
Didn’t have to twitch any of mine, just pull the tongues out & put the paste waaaay back, then watch them work their mouths for 10 minutes!
I had a horse with a cough & the vet had me giving him cough medicine - turkey baster & try to get it way back so he’d swallow it. The rascal coughed it all up on me - had it dripping out of my hair! The 2nd try was more successful, but I don’t think it helped him much.
I also had to take his temperature - the thermometer had a string on it of course, so it wouldn’t get “lost” .... I stepped into the tack room for something real quick (he was in cross ties in the aisle way) and as I got back to the door, he had this huge cough and his tail was up somewhat - the thermometer sailed by me, out the barn door into the grass. It’s one of the funniest things that ever happened in the barn. He was a really good, sweet horse - looked over his shoulder at me & rolled his eyes like “what happened?” LOL
