The Rottweiler. Been around the breed for so long that other dogs just feel inferior to them in certain areas. I love all dogs no matter breed or mix however. A bit miffed though how the show people are ruining their lines by breeding them too big and heavy. It's a WORKING dog and as such needs to be suitable for work.
Schutz, obedience, tracking and even agility = all areas where I've been graced to see rottweilers go far. They'll never be like GSD or Malinois at the top levels but good enough, and great fun to work with!
Other breeds I love include Labradors, Welsh Corgi Cardigan, Rough Collies (American style most of all) and Boxers. I am currently planning for a rottweiler puppy, when it's grown up and in a right place when it comes to training, I'll probably go for a chocolate Lab as well. ^^. I'd love a female named Doris.
Rottweilers and labs have such ADORABLE puppies as well!
