Identifying a disunited canter while riding

He'll most likely put himself right with a skip, I don't think it's comfortable for them either.

But if they don't switch it is harmful to let them continue "wrong" - I will stop a horse that is cross cantering for more than a few strides without self-correcting and start again.
 
The washing machine in the stables often goes disunited and skips across the tack room floor. it's usually when it's unbalanced with thick stuff and overreach boots etc. My indoors washing machine never does this, not sure if it's better schooled or if the household washing is just better balanced!
