Hi everyone, I just purchased a 14 wk old male Yorkie and am trying to potty train in a playpen. So far he will poop on the pee pad and sometimes squat to pee on the pad. Not too many accidents so far and I've only had him 3 days but today I noticed he is lifting his leg against the sides of the playpen and peeing. Is this normal for such a young puppy? Since I live in Phoenix and it is entirely too hot to take him outside to go, I have to have him go on a pad. Any suggestions? Thank-you.
