I truly believe that a lot of problems with dogs and their owners are rooted in the fact that dogs aren’t allowed spend enough time outside being dogs and thus develop neurotic behaviours within the home. This is hinted at briefly in the text on the page with the Victoria Stillwell training video cited above by @Soubresaut,
The problems are often due to dogs being kept in environments unsuitable to them by well-meaning masters, such as urban environments, apartments or condominiums, and even some suburbs. Our love for dogs can sometimes overwhelm our good sense as to a proper dog-friendly environment.
It is also due to careless, selfish, lazy, or merely status-seeking masters. Some dog owners wonder why their dogs are aggressive and destructive of property after being locked in a one cubic meter wire cage eight to ten hours a day in the living room while the owner is at work. These people have no understanding that a dog is a sensitive, intelligent animal much like a human toddler.
I just watched the Victoria Stillwell video and agree with her methods of training the dog out of acting upon this neurotic behaviour. She uses passive, kind methods with positive re-enforcement. It takes patience and time to do this, but it is the responsibility of the humane master to have patience with their dogs. The reward is a truely unconditional love and loyalty not found in any other animal on earth, not even other fellow humans. This should always be prized, protected and cared for, as it is an incredible gift.
Conversely, anyone using electric dog collars should be forced to wear them for a week by an angry spouse. But my first choice is that they should be beaten with a baseball bat.
