Hooray for you and Layla's new place!
We have a yard, but never use it because (a) it is not fenced (b) there are foxes and (c) there are hawks.
As long as Layla gets plenty of exercise through walks and playing indoors, you both should be very happy in the new condo.
Is there a deck? Have you thought about doggy-proofing the deck maybe with netting around the edges? These yorkies somehow manage to squeeze through the teensiest spaces.
Good luck with the move! Let us know if you need help with moving...I will be happy to watch doggy while you are packing and lifting all the boxes.
