I have a cocker spaniel. We have never had any problems with her, other than her being too friendly! She always jumps up when people come into the house, but she doesn't do it to strangers, which is good. She always comes back when we call her, it was very easy to train her. She always eats her dog food, but she does beg for whatever we are eating, but I guess all dogs do that! She is very energetic, but she will calm down if you give her a lot of fuss and a dog chew. She is very well behaved with children, my 7-year-old cousin loves her! We also have a cat, and we have never had any trouble between the dog and the cat. We have two other dogs as well, and they all get along fine. She is the best behaved out of our three dogs (cocker spaniel, staffordshire bull terrier, jack russell).
