Why Do You Want a Dog?

Here's a look at the most common reasons people acquire a furry friend. Knowing why you want a dog will help you choose the right one for you.

Companionship: Children learn responsibility and receive unconditional love -- but make sure your expectations for their help with the dog are age-appropriate. Adults gain exercise partners. Elderly people gain friendship.

Assistance: Guide or service dogs are trained to work with people with physical disabilities; potential owners must apply for dogs and attend training.

Security: Guard dogs with proper training are alert, protective, and sociable family members.

Sport: Field-event dogs run obstacle courses and retrieve objects with ease, whether for competition or fun.
