In poodles the males are more devoted and affectionate. So I thought the same might be true in the yorkies.
2 males raise their legs(poodlesl) cuz I waited beyond 6 months to fix them, but never in the house they are very clean.
2 dogs 1 yorkie and 1 poodle squat and never raise their legs because they were fixed by 6 mos. and they are both very clean.
My yorkie hadn't been too cuddly till just the last few days and now is wanting to be picked up and held just like my male poodles.
