When I 1st got Missy she was the only yorkie in the house, she was sad when I left and acted a little sad or shy when I returned home. I felt bad for her so I got her a companion Max. Now when I leave they are both playing and happy, they give me lots of kisses when I leave, they play and nap all day, then when I come home they are both so happy to see me.
Having 2 yorkies works out great for me, they keep eachother company when I am not there and they have lots of fun together
