I've got 3!
The oldest is 16, she's a mungrel. I believe her dad was a Staff and her mom was a Jack Russell
The middle is Ruby, she's just turned 1 and is a Rottweiler/German Shepherd cross
The youngest is Poppy, she's 10 months old and is a miniature Jack Russell
Yes. I have a pomeranian mix breed... he's the first ever pet my family has ever had and we love him!
You should definitely get a dog but make you sure socialize the crap out of him/her when they are super young.
