Hints:
shepherd
When a book describes a dog as an ideal hunting dog, it probably means that the dog won't be happy living in a small apartment. Dog breeds vary in popularity as the years go by.
One of the most popular dogs these days is the German shepherd. This is because it provides protection as well as companionship. The family should be warned that these dogs grow up to be very big, and may be too powerful for children to handle. If space is limited, a toy dog may be a good choice. These dogs are very small and easy to train. They don't need to be walked daily, since they can exercise in the space available in the home.
