I have my 2 y/o Piper in a medium crate from Petsmart and plan on buying a pink crate(
PetEdge: ProSelect Fold-Down Crates Fashion Colors) for my new baby Leah. Right now Leah is baby-gated in the bathroom until we get the crate. I have 2 kids who constantly leave stuff on the floor--I don't trust either yorkie to not chew up/eat things they shouldn't have. I know they find things when I am home and I would be devastated if something happened to either one of them. BTW, Piper's 3lbs, and Leah is 2.5lbs--so the crates have plenty of room for them.
