I've narrowed it down to 3 breeds. They all display things that I like in a dog and want in a dog. I simply cannot decide. I am not a novice when it comes to dogs so I don't want to hear "you really should find a dog that fits your lifestyle"...Trust me these breeds fit my lifestyle, I've already determined that. The question now is I want to do competitive obedience and conformation events with my dog(s). The Doberman I understand would be best for competitive obedience. But how would it co-exist with other other dogs if I decided to get more? The Boxer is more submissive then the rest of the breeds which I covet. However their trainability is up for question. The Rottweiler has the best looks in my opinion. But how are they versus the Dobbie and Boxer when it comes to competitive obedience. (probably comparative to the boxer). Which dog sheds the most? This is important to...there is one thing for some reason I've always feared and that is while at conformation which dog is least likely to bite the judge when the judge looks into it's mouth?...Plz help me.
