Rotweillers with bad temperments? Never met one. What about owners with bad temperments? What about Akitas, chows, pomeranians, and Jack Russells?
Humans with bad temperaments often are amenable to rational discussion and calming words. A dog in an attacking frame of mind is another matter.
Do a quick search using insurance companies and banned dogs and you’ll come up with a list. One is at: http://www.dogbitelegalcenter.com/resources/common-dogs.html but it’s partial.http://m.hg.org/law-articles/area-insurance-and-reinsurance/6862/Insurance_Companies_Balk_at_Covering_Dangerous
Here in LA wolf and wolf hybrids have to be kept on leash & muzzled when in public. They also have to be neutered unless a special permit is obtained for breeding purposes beyond normal licensing requirements. They are not allowed at dog parks and they have to be kept in a fenced yard with something like a 12 foot anti climb fence that is protected against digging. Doesn’t matter what generation of wolf/dog hybrid it is or the temperament it has. There is one wolf hybrid that the sweetest temperament and gets along with every dog it meets. The requirements still apply. We used to have a couple of Timber Wolf Hybrids that came to the dog park (5th generation) a mother and daughter. My Airedale did something that ticked off the mother and they both walked down on the 90 pound Airedale and put him in the corner of the park. The owner pulled them off. If my Airedale hadn’t backed down the two of them would have killed him. They did the same thing to several other dogs and they never returned to the park.
Any dog can be a problem dog. Mostly it’s problem owners. Those who use the dog as a substitute for a piece of their anatomy to prove how tough they are, those that don’t train their dogs, those that don’t spend time with their dogs and keep them exercised and socialized, those that aren’t the pack leaders of the family pack and have let the dog assume that role. Unfortunately you do have dogs that are improperly bred (one aggressive dog bred with another or two that are nuts, etc). This happens with really popular breeds and the fighting breeds. The result is unstable dogs and as it goes on down the line the dogs become increasingly unstable. About 80% of a puppy’s behavior comes from the mother and if she’s not socialized and well adjusted the puppies won’t be either without a lot of work. with dogs being specifically bred to be aggressive (fighting also) the chances of its puppies coming out aggressive really increases. Those who use the dog as a substitute for a part of their anatomy or those that think they need an aggressive dog to protect their families tend to get dogs from lines like this and you get trouble.
I stay away from the dog park on the weekend because the under exercised and under socialized dogs show up with their owners. I get a kick out of the young male who has his pit or rott on a very heavy chain leash using the chain for a collar. Of course I stay away from him and his dog.
My neighbor raises English Staffordshire Terriers and has some of the top show dogs in the country. They are friendly to humans once invited inside but very dog aggressive. Part is due to the breed and part is due to the males being stud dogs. When I visit Airedale kennels we have to keep my neutered male away from the stud dogs too. They would try to kill or injure my dog to protect their harem.
Right. I don't think they allow them in nursing homes either.
