I currently have a one and a half year old shorthair female Chihuahua who is the most adorable (don't we all say that?) five pound little bundle of energy ever. I love her to pieces and she is my little child. I am contemplating getting her a sister from the same breeder and want to know the pros/cons of two little dogs vs. one from those of you that either have one dog, two dogs, or just an opinion! Please post your thoughts on this other than the obvious (eg. two dogs eat more more, poop more, cost more, etc) Thank you!
