For instance, some believe that dogs that were bred to herd cattle may try to do the same with your children. If this would be a problem, you might want to choose another breed. Your next choice is whether to bring home a full-grown dog, or a puppy. Puppies are cute, but can have some bad habits, such as chewing on things, whining, and leaving puddles everywhere. An adult dog, on the other hand, may be calmer and already housebroken.
Adult dogs have their drawbacks, too, though.
A full grown dog, like a grown adult, may be more set in its ways. You can teach an old dog new tricks, but you won t make a standoffish one into a friendly, bouncy member of the family overnight. If you choose a breed that needs lots of exercise, make sure that someone in the family is willing to take the dog out and play with it. With a smaller dog, that may just mean taking it for a walk. Larger dogs may need more exercise, and you should make sure that you are up to the challenge.
