The recent dog mauling in San Francisco and trial and subsequent "Our Opinion" by the Imperial Valley Press have focused the attention on the danger of owning a "tough" dog the need to confine and control and the danger of "training them to be mean."
Responsible dog ownership is not just to confine and control your dog once you feel that he is a problem. People need to be aware of breed characteristics, how big a dog will be once he is mature and how much space he needs, among many other types of helpful information.
They also need to know resources available to them throughout their community, such as: local veterinarians, kennel clubs, breeders and trainers. Most importantly, they need to take action to properly socialize and train while the dog is still a puppy.
I have been training dogs for over 25 years. I can tell you that owners with aggressive or out-of-control dogs, for the most part, did not intentionally train them to be that way, nor did they know that they should or could start training and socializing their dogs while they were small and easily managed puppies.
