If I'm getting a girl I always seem to like the smallest one not sure why I just like little girls
....If I'm picking out a male I like the one that doesn't rush up to the side of the kennel or yard wanting petted or picked up.. like the one sitting back checking things out first, being relaxed and a little cautious when someone new walks up,...and I don't like the one that stay's on the tit or in the food bowl the longest like it's always hungry or a food hog ...... my .02
