Oh yea, Lute reminded me of a good point.

Yorkies are NOTORIOUS for being hard to potty train. I think all small breeds are hard but I've owned 4 different small breed dogs and my 2 yorkies were the hardest to train.

Bailey was 50% pottytrained at 6 months (didn't poop in the house but still peed). He just recently became fully pottytrained at about a year old

Molly is 7 months old and is just now getting the hang of going outside to go potty. I'm guessing it'll be another few months before she's fully trained as well...
