My new horse was recently introduced into a herd of 6 other horses. He has many bites and wounds. He is doing well now but 3 of the bites that are under the saddle pad have not yet begun growing hair. I am very concerned it will not grow back. I have been putting Tri Tec on them. Does anyone have any comments on weather the hair will grow back or not and is there a product that works better for encouraging hair growth. I did stop riding for a week but have been riding for a week now. Thank you in advance!
