Simply not true. And they are great with kids. So great, that circa 1905, they were the #1 choice of families with small children when choosing a dog (USA). They will tolerate a lot of anything from a child, including nutsack pulling, biting, stepping on their paws, etc. Sharp and loyal and a good all-around dog, can hunt and there is no better house/guard dog, IMO.
Pit bull pay no mind. Step on a house beagle's paw and you'll get bit, grab a GSD or lab by the nutsack and you're probably getting stitches.
Different strokes, I guess.
You're like the politician who has no gun experience talking about what we should ban, it seems. Only with dogs.
