My 6 yr old TWH mare got caught in OLD fence that the cows pulled out of a hedgerow. She severed her front tendon on the hind leg. Long story short, I ended up buying a cold laser, cost about $3000 and using it on her leg 3x to 4x a week for 6 months. She is sound, I rode her all summer/fall after the injury the August before. She of course had proud flesh,so we used a new product on that. (Can’t remember the name, but it is gray and vets have it), As of 20 months after she has a very small bump. I continue to use the laser on my old dog , any horse injuries etc. It is a great tool and is incredible for healing. Hope this helps.
