We put down the dog I grew up with last year after 15 good years. Princess the Sheltie (my mom picked the name). My stepdad brought his Lab/German Shepherd/Rottweiler mix named Bailey into the family a couple years ago. She was a rescue dog and we aren't really sure how old she is although I'd guess around 5-6. She's still a little skittish with strangers but a bit of a petting slut with anyone else.
I've decided once I get a decent sized apartment or a house, I'll be getting a Greater Swiss Mountain Dog. A photographer I worked with a few years back had one and it was the most striking dog I've ever seen and extremely well mannered...at least when he wasn't barking at me through his massive chest.
