A recent study conducted by the University of Pennsylvania on aggression in dogs found that Pit Bulls and Rottweilers aren’t the big, bad MFers of the canine world that most people think they are.

The study asked questions of 6,000 dog owners of differing breeds about their particular dog.

The most aggressive dog breed?

Dachshounds. Followed closely by Chihuahuas.

I can verify the dachshound and chihuahua conclusion through personal experience. My family (when I was a lot younger) has had both breeds as pets. Actually, some of my family still has doxies. A couple years ago Mrs. Old Fart and I took one of our most relaxed and gentle greyhounds with us on a trip to visit the family with doxies. I wouldn’t have believed it if I hadn’t seen it with my own eyes. One 60 pound greyhound being attacked by probably around 4 or 5 minature dachshounds. Yep, these were mini doxies! We saved the greyhound from doom (LOL), but she was petrified of those doxies the rest of the visit.

Oh, and in case you were wondering… greyhounds ranked as one of the LEAST aggressive breeds.
