Dogs bring years of joy and companionship, but they are also a big responsibility. That's why it's critical to know what to expect before you get a dog. Deciding what breed to get is as important as deciding whether to get a dog in the first place. Being a responsible pet owner requires some serious and careful research to determine which of the 158 dog breeds registered by the American Kennel Club. (AKC) is right for you and your family. The AKC provides the following items to consider before choosing a dog.

n Temperament— A dog may be with you as long as 15 years, depending on the breed, so make sure he has a personality you can live with. Is he active, or subdued? Is he easily trained, or strong-willed? Is he friendly to everyone he meets, or aloof toward strangers?

n Exercise needs— All dogs need exercise, but some are more active than others. Some dogs need a lot of attention from family members, and regular activity to prevent them from becoming bored and destructive. Others are happy to spend the day sleeping on the couch.

n Size — All puppies are adorable, but they grow quickly. Ask the breeder how large your puppy will become before you bring him home. Keep in mind that large dogs require more food and space, and even some small dogs need lots of room to run around.

n Grooming Needs — All dogs need grooming and most will shed to some degree. Long-coated dogs are beautiful, but require a lot of effort to stay that way. Short-coated dogs are easier to groom, but may still shed, and may require protection in cold weather.

n Cost— According to a recent AKC survey, the average pet owner spends up to $1,700 annually on food, vet care, grooming, toys/treats and training. In addition, pet owners spend up to $1,800 on one-time expenses such as acquiring the dog, spaying/neutering, and start up supplies, including a crate, a dog bed, and leashes and bowls.
