Does anyone have any suggestions - horse working soft happy forward In Trot work, but pigrooting bucking and disuniting in the canter reluctant to go forward. Seen chiro, masseuse, farrier, saddle fitter, does it bare back aswell, been scoped with no ulcers, change of diet with no difference, feels fine all over. Thinking a vet? Been happening for two months now. Thankyou
