Do you think that there should be bans on certain dog breeds?

I agree with you. I don't think that the breed is the problem. The problem is that owners of certain breeds don't know how to take care of their pets. A friend of mine is a pit bull owner, and she was telling me that pit bulls become very attached to their owners and need to be around people a lot. She explained that when people leave their pit bulls chained outside all day, they become very disturbed because they don't have that human interaction that they need. And the only way that they know how to deal is by acting aggressively and biting people. Pit bulls that are well taken care of are some of the sweetest dogs I've ever met. I strongly believe that any negative behavior associated with any specific breed is entirely due to the owner not properly caring for the dog. There are a lot of misconceptions about many different dog breeds, and banning a certain breed just adds to the misconceptions and encourages ignorance.

Yes, some dogs are too naughty to control and sometimes these dogs may bite others. It'd better to ban to breed.

That doesn't sound like such a bad idea. I know in some cities Indiana there are certain dogs that you cannot have in an apartment building. But I'm not sure if they actually come out and say you can't have that dog at all. But it is a city ordinance, not just a ban by the apartment complex. I also have heard of people not being able to get homeowners insurance because they owned a big dog like a pit bull or a rottweiler. This is pretty scary too. I think that it is good to educate people in all aspects. So you're idea about offering classes to help people take better care and train their dogs is a good idea. Happy posting!
