1st week treat
2nd week treat and band for free galloping

Band all 4 toes up high over the knuckle
Use a rubber washing up glove (the thumb ) cut it 5 ml wide so you have a rubber ring and it will have enough give in it to cross all 4 toes as apposed to a rubber tube with no give
Makes sure it sits in behind the inside and outside toe pads on the underside

One might be enough for your liking of firmness , if not , double it with another band

Ps if your struggling to keep the split dry which is the main concern , use a touch of diluted bleach , dries it out and sterilised also ( muzzled to not lick or digest treatment! ) For extra help with healing can use Rawlieghs antiseptic ointment ( brown tin ) it has honey healings in it , once every second day , it adds moisture so not everyday

Around 2 weeks min and should be perfect , take bands off 3rd week pending results and free gallop again and check , if it splits again in a paddock it aint ready for a track turn

Repeat process

Good luck , dont worry too much bud
