small sized only because I'm 4'6" tall! I'm in a wheelchair without much of a lap so smaller sized dogs are more my size no pun intended. We have a 5 yr old male pugapoo who really believe he is just a furry child and we have a rescued MinPin/German Shorthaired Pointer lil girl who we are guessing is about a yr old very friendly and cowardly all at the same time. Gizmo is stocky and about 12 lbs while GiGi is long legged and slim at about 8 lbs.
I didn't vote as mine are 25-120lbs. I prefer a medium sized 30-40lbs but I really like big dogs too. I like the giant sized dogs but don't know that I could actually have one around myself. I don't like to many small breeds but there are a few I like.
I missed the pedigree dogs exposed. It sounded interested. Although it really depends on the breed to say if they are over bred or look like they used to. Some breeds are not that much over bred and haven't been ruined (at least not yet) or watered down/changed. They also look pretty much the same unchanged by time. There have been so many changes to breeds over time it is amazing to see and sometimes sad or crazy to see how they are today.
