Pawing is annoying. But, I’ve had an experience over the last 2 years or so that has caused me to think about it in a different way. The horse is trying to communicate, though we may not agree with what the horse is trying to say. Kind of a long story, but here we go.
My horse is the son of a pawer. His sister is in our barn too, and she paws as well. At first it was just a little when the trailer stopped or on the cross ties and I usually just ignored him. I wrote it off to his upbringing LOL! But, in the summer of 2020 things got really out of hand. He pawed madly in the trailer and in the cross ties. I could not for the life of me figure out what was going on. All attempts to stop it were unsuccessful. Around November he got lots of hard lumps on his barrel, had the vet out, had the lumps surgically removed, and found that they were eosinophilic tumors from reactions to bug bites.
Spring of 2021 he started the mad pawing again and broke out in hives. Gave him dex for the hives and the mad pawing stopped. Duh! Duh! Duh! Poor thing was trying to tell me that he was itching to death! Put him on Benadryl for the rest of the summer and the hives and the mad pawing stopped. He was like a different horse. Kept him on Benadryl until late November but wondered when I would have to put him back on it.
Fast forward to now, when the mad pawing started again last month, I put him back on Benadryl. Mad pawing stopped. But, he was still doing bouts of pawing on the cross ties, what I would consider his baseline level of pawing. So I have been working lately to stop that because I know now that there’s no reason. A couple of sessions of backing up a few steps with a stern QUIT or WHOA every time he tries to paw seems to be working. He’s also learned to be much more patient on the trailer, which is likewise a lot easier when he’s not itching from the inside out.
So, I agree with most of the advice above - if it’s just a little boredom pawing, it’s worth working on to get the horse to stop. But make sure the horse isn’t trying to tell you something else. If it hadn’t been for the eosinophilic outbreak, I’d still be trying to fix the wrong thing. I feel pretty bad that it took me as long as it did to recognize that the poor guy was doing his best to tell me something was wrong and I just wasn’t listening.
