I am very glad we choose to get a second Yorkie... Chewy loves Sadie for the most part. They play, they snuggle and sleep together... He has liked her from the start. But he gets jealous sometimes and gives us the cold shoulder! It doesn't last long but I feel horrible when he does this. We give him tons of attention and try to make him feel more loved then ever.... I'm sure it is an adjustment for the older yorkie to have a baby brother or sister but worth it in the long run.
