When I decided 'we' (LOL) wanted a yorkie, it was going to be a girl. My husband was fine with that. But when we got to the breeder I spent time with Samson and his sister and fell in love in love with Samson. My husband still tells me (1 year later) that he's so glad that we picked Samson. He plays so much with my husband and is such a cuddlebug with me.
Go by the personality of the puppy - that will be what's important
