Here is the dog trainers 10 cents.
I have been training dogs for twenty years, nice dogs bred to nice dogs give you nice dogs and puppies. regardless of breed or papers.
all urban dog trainers are seeing an increase in aggressive dogs, and puppies too.!
Mostly the cross breds/humane society rescues.
Possible reason suggested is the spay neuter programs have taken a lot of nice dogs out of the gene pool, and the random breds we see are are the result of poor stock, mostly owned by low income people who do not spay neuter, get 50 $ for a puppy at the feed store.
Internet sales of dogs, and riduculous prices on puppy mill dogs encourages people to breed for money.
I see nasty dogs of every breed, right now I have an aussie mix thats not worth a dime, a nice lab, which is amazing, so many labs are now un fun.
I have a really nice bully boy, ie pit bull, he is pushy, but very workable with an ownere that works him.
I have only seen one german shepard I would own, from canada.
again ,its the breeding, or lack of quality contol on breeding... and yes the gangs in the inner city breed to fight their dogs.
dog fighting is alive and well in the USA!
I have no patience with nasty, hard biting puppies, they grow up to be nasty dogs. and there is no cure.
pits can be very hard and nasty, if bred that way, and when they make up their mind to do violence they are built for it, and it happens..... but i have seen some very scary labs!!! and people think they are all good with children , thats a dog trainers joke......
