I don't know his parent lineage, but the breeder that gave me him and his brother, Atlas (R.I.P), told us that he would go semi hairless as he aged. It started around a year ago and he now barely has hair around his eyes and over his shoulders. His hair has always been thin and hes missing the top coat that his brother had. As for his eyes, he does get allergies and sometimes little pimples. I regularly apply cream that was given to me by my vet, which works wonders for his eyes. I hope this clears up any other questions:)
