There's the rub.
I've seen people who will walk their kids past dogs they don't know, and say "If he bites my kid I'll kill him..."
Well that's great, you neandertal, but if he kills your kid your kid's going to be dead.
Like I said, I don't have a problem with liking various and assorted animals, including horses, but recognize the potential for danger and keep them and the public, including your own kids, safe. It's idiotic to "prove" a point with animals using kids.
I'm proud of my son, he is careful with his dog, he doesn't take him out in public without a leash, he has always made sure to spend lots of time with him and socialize him to other dogs and people in a safe way, and he plays with him when he's eating so he's acclimated to that. I keep telling him to get a muzzle but he's having a hard time finding one big enough. Not that Snoop needs a muzzle, but it would be nice for when they're out and about or when they have company...just so people don't feel threatened, and to provide that extra degree of security. It won't hurt the dog any and it covers all the bases.
