Dog contol is a lot like gun control. Once we identify "evil dogs" then we can make the quantum leap and identify "evil guns".
I don't know about that. Dogs are living beings that are influenced by many things... breeding, training, environment, instincts, etc. You can never completely predict the actions of any living being. Therefore dog control is a necessity, much like people control.
Tell your dog to sit and stay and eventually it'll move and do SOMETHING....benign or bad. If I tell my .45 to sit and stay it will be their until time stands still.
Controlling guns by laws is completely unnecessary because a gun is inanimate. Controlling the people is the real issue.
Relating dog control to gun control, I think, is a stretch.
The worst breeds to work with are usually Asian breeds: Shiba Inu, Chow chow, LhasaApso, ShihTzu,
Have you really seen issues with ShihTsu's? I've NEVER seen one that was anything but the most loveable, docile pet. I've had one, other members of my family have had several and all have been totally adorable. I've never seen anyone of them that has had a mean tooth in it's head. We've raised 7 grandkids with at least one around at all times and they love babies and anyone who will pay them any attention at all. I've never seen a more affectionate animal.
As you know, they are in need of a haircut once in a while. I could sit my little Mindy down, put my finger under her 'chin' and clip the hair under/over her eyes with scissors or a clipper and she wouldn't evern blink. She was completely docile and totally loving. NEVER barked or gave me any worry. If we played and she grabbed my finger a little too hard with her teeth, a simple "ow" would make her release and look sorry she hurt you and ask for forgiveness. Any of the ones our family has/had would behave the same way.
I had to put my 15 year old down a few months ago and it affected me nearly as much as when one of my family members died.
The reason for the length of my post is that I am totally shocked that you would report that they have 'issues'.
If you've had problems with any, I'd like to hear about it.
