I am curious as to if most Yorkies pretty much potty train themselves with the pee pad? As soon as Holly could walk around on her own, around 3 weeks, I put a peed pad out for her. EVERY SINGLE TIME that she needs to pee she will find that pee pad and go potty and poop on it! She never goes anywhere else. I don't have to clean ANY messes up. Is this common? Just curious. Even if it is common I think that she is one smart pup!!
