disunited canter

[masonandbecca]

sorry if i've posted this in the wrong place, or this has been answered elsewhere
my horse can canter perfectly in balance on both reins, however when jumping him over the height of about 2ft6-2ft9, he lands disunited. he's learning to change legs in front after the jump for some of the time, however are there any exercises anybody could recommend to help me keep him in balance, and to help him land in a correct canter?
thanks, becca x

Sorry can't really help, but will be interested to see what everyone says as my boy does the exact same thing but then afterwards starts to lean and will not come back so I can correct his lead , very awkward!
