Bob, I am going to throttle you. How can you be so callous?
I am sorry but the horse took several months to heal and, even though the vet has declared her "healed", that doesn't mean she still doesn't have some issues.
Take your time with her. I would have a chiro evaluate her, now that the vet has given her a clean bill of health.
I agree with a lot of walking. I would start out walking her on the flat. If you have hills start her slowly on the hills.
Do you now have shoes on her? If she's barefoot, there is no question that I would put boots on her, for awhile anyway.
That's JMHO and what I would do. "speeding the process up, according to Bob is not what I would do. Don't worry about any altercations on your thread. Bbsmfg3 and I have agreed and disagreed, long before we both ended up on this forum. It just so happens I strongly disagree with his approach this time
