Swinging quarters to left when in right canter?

[Lill]

This is what Blue appears to be doing now.

Have had his back checked by a physio and his teeth done in the past month or so as he wasn't cantering properly on either rein.... after i did a lot of leg yielding in canter which i have to say i won't be trying again - ever!

Now his left canter is back to normal but in right canter he still feels a bit stiff and tries to go hollow and seems to swing his bum left a bit?

If i put my left leg back to push his bum back straight he goes hollow?

Am not sure whether to get the physio back out again? She did say he had sore muscles on the top of his bum?

Could you be using too much hand in relation to leg? I can aways tell when I am because PF swings out but on both reins.
Course, he might be a bit sore as well.

Are you sitting straight and weight bearing evenly in your saddle, dropping a shoulder or hand, looking down? My youngster adapts herself immediately when I am not straight yet my older horse has got used to my lazy bum I think!
She too has had everything checked. I got my dad to take pictures of me sitting and riding away and towards him and the results were quite startling!
