Bailey was a rescued animal from a previous owner that had no business owning a dog. He originally required a great deal of trust building and training to temper his violent tendencies. This all happened in his first year of life. By the time he was 2 years old he was transformed into the most loyal, obedient, and trusted companion. His aggression was under control and he was became a much love member of the neighborhood. Even the elderly lady next door would make biscuits for him and he would visit her daily to check on her.
Bailey's intelligence was beyond anything I've ever encountered before. Besides learning the basic commands such as sit, stay, leave that alone, etc... He demonstrated mechanical understanding as well. He figured out how to turn door knobs and open doors as well as operate the latches on gates, to the dismay and horror of many a jogger. Fortunately, his intentions where always to join in play and not to harm.
Bailey lived to be a little over 6 years old when cancer suddenly took over and ravaged his body. I was told that it was a highly unusual and possibly a delayed reaction from something he was exposed to before I took ownership of him as a 6 month old. It has been 15 years and I have not yet chosen another dog as a companion. If I did, I would definitely seek out a Doberdane. Unintentional crossbreeds occasionally happen and when this happens it is possible to get one of the pups for a minimal price. These dogs are a bargain at any price.
