I have two female dogs and they are as different as night and day. My ShihTzu is a very laid back gentle little lady but has a temper when she doesn't get what she wants as fast as she thinks she should. Then I have a MinPin that is hyper and very possessive. As for getting along with cats, they are not good examples because they have never been around them. They like to chase them and play but would hurt a kitten because they play too rough. Guess they think they are like those squeaky toys I buy them. If I had gotten them and a kitten all as babies, they would have learned to get along together. I think they are like people and get a bit grumpy and hard to get along with as they get older.
