We blow it for other dog owners all the time!
How many of us feel bad about the reputation that the Pittbull now has? Not to mention all of the other harder to handle breeds who become a danger to people... Don't you think it would be a better idea if we were MORE SELECTIVE over who gets to acquire and raise harder to handle dogs? It would be so much more safe knowing that one had to work to acquire a licence to raise that Rotty you see walking toward you... because you know that the owner/handler has an education... you know you don't have to worry for the safety of your child next to you... The luxury of knowing that it's been "taken care of" would make for such a calmer society around people who have dogs that have a reputation.
I'm not talking about the poorly trained Poodle or misbehaving Maltese who's under trained out of control and/or nippy... this too is an issue of sorts, but cannot compare to the mass fear and destruction that an aggressive Pitt or riled up Rotty can accomplish.
We need to remember that not all people love/like dogs. We live in this world and share space w/ people who don't share the love. Every one of us that has a dog are setting an example for the next. We have the capasity to ruin it... if we don't set a proper example, (for even something like picking up after a dog eliminates... ). For every dog owner that "blows it" you are setting up the next dog owner to suffer your irresponsibility.
