Glad you're ok. We had a mean dog in our area that chased my son.after several calls to the police and no action taken. I broke the owners jaw and told him everytime I see his dog loose I will break his jaw again.... it was never loose again.
Awesome! Sometimes people just don't get it. He does now obviously.
I love dogs, have two, and have met some great pit bulls. So I don't think you can condemn a whole breed, but one also cannot argue some breeds act with more reckless abandon than others do. Chows are known to often be one-person dogs, which is great if you're that one person but beware if you are not! Surprisingly enough, Dalmatians one has to keep an eye on also. They are very protective.
However, whatever dog (or coyote, or anything) that chases me or mine is risking getting a real nice broadhead through it pronto the next time it acts like that, or chases a neighbor kid. It's not the breed. It's an individual case basis. And threats need to be removed.
I'll bet six-foot spiders would have open season on them until all of them were eradicated. And I'll also bet some people would think they were cool. Until their kid ended up in a cocoon.
I am not comparing pit bulls to six-foot wingspan spiders, let me be clear on that. But I sure would rather have a mean wiener dog after me than a pit bull or other dog capable of doing real serious damage like in the case of the OP. GLAD you were prepared, and your mother's old boyfriend needs his jaw broke, too.
