Buy one that fits now. A blanket that is too large is more likely to cause rubs (shoulder and withers) than one that is too small. If you buy his size now (measure either from the centre of the chest to the furthest rear point of the rump measuring along his side, or measure straight from the top of his withers to the top of his tail). His blanket size shouldn't change with weight gain (I suppose it could, if he were to gain 200-300lbs
but it will likely stay the same).
In my opinion, a horse is the animal to have. Eleven-hundred pounds of raw muscle, power, grace, and sweat between your legs - it's something you just can't get from a pet hamster.
