New companion Horse is extremely difficult!?? Wont let anyone touch him!!

So Sad! After losing her heart horse at 25 years a new companion horse was needed quickly.. Glyde is a big 2 year old gypsy vanner and after 6 weeks of owning will not allow any one to catch or touch him other than taking treats and while giving treats allowing a nose touch.. Its all spiralling down hill and becoming dark for everyone! What Can be done?? Join this channel to get access to perks:    / @steveyounghorsemanship
