Hi and Welcome to YT!
Aw! He sounds very happy... makes you want to bring him a new toy everytime you come home, just to see his reaction!
If I walk in the house with any bags, I have to put them on the floor and let my pups do a 'bag check'. They each have to stick their head in each bag to see for themselves if I brought them anything.
Once I bought new hair bows for them. They formed a line and each one waited till I put a new bow in their topknot. Nothing neat or pretty, mind you, just stuck in their hair so I could get on with putting away my groceries! Then they spent the next 20 minutes running around the house admiring each others bows! I can understand excitement over toys, but bows?
One thing about yorkies, they will keep you laughing!
