The reason that it's hard to have to have a rational discussion is because people are coming after my well-managed, highly social, highly trained pets. One is 35 pounds, the other is 42 pounds, and no one is looking at the 150 pound vicious St Bernard down the street from me that has an extensive bite history and runs at large regularly. Looking at dangerous dog laws makes a world of sense. Looking at "pit bull" laws when no one can even define what they are is just crazy-making. What is a pit bull? Seems easy enough, but it isn't. Some "pit bull" laws include huskies and presas and cane corsos... All under the label of "pit bulls."
I am ALL for legislation that requires responsible ownership. My dogs (shelter dogs) are altered, chipped, trained, contained, have passed TDI and CGC and have multiple perfomance titles in 3 venues. My yard is fenced. None of my dogs have ever been lose. I wear a fanny pack and clean up after my pets. I carry a million dollar liabilty policy, mostly due to my teen aged drivers, but despite all of this, I could have my dogs taken from me or have to move and the owner of the vicious and loose St. Bernard gets to skate free.
It causes frustion. Certainly that isn't entirely irrational.
