I've got a chessy as well. They're unmistakeable. Absolutely beautiful dogs. Mine is SOO loyal, and rediculously smart. Bound to be the sweetest dog I've ever met. He's very tender and careful around my planes, but if I crank up my car he HAS to chase. He can't NOT chase it. He's such a good dog though, I've literally taken food out of his mouth and he hasn't so much as started to growl. He's very protective of his home turf. If we're outside, he can deal with strangers (as long as they're not aggressive towards us)....but I pity the stranger that tries to come in our house without us being outside. He's great with kids...we have a picture of an 18month old child taking the tennis ball out of his mouth (he's become REALLY attached to his tennis balls) and then he played fetch with him for 30 min's. Never knocked him over. He also licks his mouth before he drools, and won't come inside or get in a car unless directly told to. He's about to be 10, I think. He looks a lot like yours. He's at about 120lbs as well. They're great dogs, aren't they?
