Today, I see too many people on Public Assistance thinking they struck gold by buying a breeding pair of dogs and selling puppies for $3,000 each. With no regard for genetics or personality profile, and generally deplorable living conditions, is it really any wonder why people who buy these dogs have broken hearts when it dies from cancer, suffers from hip dysplasia, or any number of other health or personality disorders?
I suspect a lot of the issues with dog bans in the UK are related to unscrupulous breeders and owners who are clueless about owning a dog, much less a large active breed. Do they even have basic dog-handling skills?
If the owner is not the Alpha "pack leader, any breed can be a problem. Grandma had a Minature Poodle and treated it like a child. Around other people, it was really aggressive, even with young kids as it was asserting its dominance over its 'territory', Grand Ma's house. Finally one day, I had enough as a ~70lb kid, and when it growled and snarled at me, I had enough and smacked it halfway across the empty room. Never any trouble with that dog after that as it figured out, the pecking order between the two of us.
