I agree that there are a lot of agressive Doxies out there. From what I've seen , it's a combination of breed characteristics mixed with lazy people who don't know how to socialize and train a intelligent but stubborn breed. I see many Doxie's in the hands of inexperienced or unknowlegable dog owners who do not take the time (months) it takes to socialize Doxies adequately to animals, children, and difficult situations. They also constantly baby or carry these dogs, allowing them to feel dominate over other dogs below them and also allowing them to become territorial over a person or object. Doxies are not a dog for the novice or undedicated owner. They need obedience training, stimulation (directed properly), and they need to be taken into the world where they can learn not to be fearful-agressive. I have owned many powerful breed dogs, Rotts, shepards, cattle dog (intelligent, needs good training & a job), great danes, bull terrier, etc. Doxies are being bred like crazy and most people who get them don't know what kind of dog they really are - For example, they can be really hard to housebreak. My heart aches for all the Doxies sent to homes where people are unaware of this problem, and probably cause a lot of the agression problems with Doxies when people are harsh with them during housetraining because they are not being prepared for the amount of time it can take to housebreak Doxies. My Doxie is a good citizen today because of what amounts to me spending the first year of her life making sure she completed her training, was not allowed to behave agressively in scary/new situations, persistance with the potty training issues. I could probably accomplish this with almost any young doxie I was given, so I kind of have to blame owners for most of the problems with them. You can't just get a Doxie and expect it to train itself. (This can also be said for many of the other so-called problem breeds: Pits, etc.)
