Re: Serious dogs
"Serious" may mean a dog who can go civil more easily when he is himself threatened. It may also just mean someone is bragging about their own dog, making him out to seem "tough." It may also mean a dog who is serious, very little sense of humor. The word may be used for dogs who are sharp and have nerve issues. It may also mean a dog like Grimm's sire, a very bold, secure, but extremely über-dominant dog that defends his territory against all comers. His son, Grimm, is the opposite-- completely socially open, envisions all guests to be his adoring audience, if you have a pulse, you're his friend, etc.
