I'm a new yorkie momma too!! I got a x-pen to put her in, the wee pads are at one end & all her comfort stuff is at the other, I have been so amazed & hate to brag on her (ok knock-knock on wood
she has went straight to her wee pads as soon as I put her in it! to my knowledge the breeder had not started her on this, they are just so intelligent! I would get the x-pen instead of the playpen I tried the playpen w/my poodle when she was a puppy & b/f long she had put a hole in it! my husband cut mesh out of one of the boys swimming trunks to patch it & that lasted about a day!! it took him 2 hrs to sew that!!! it was worth it tho' to see him!
