My elderly dog recently died.  I still had my big mean dog but he was slowing down and not getting any friendlier.

So I went to the local animal control and adopted a little chihuahua mix.  It is my firm belief that the little dog safed my life.  He's so full of energy and moxy.  He took over the house.  The mean dog that hates everyone, loves that little guy.  Except for the 80lb weight difference, they are almost the same dog. 

He's my first little guy and he's so much fun.  But the mean dog is getting old and has never been much for playing. So I decided to adopt another chihuahua mutt, a girl so my little guy could have someone to play with.

My question is, will they get along or fight over the girl.

Is possible to have too many little dogs?
