THERE ARE AS many reasons for wanting a dog as there are breeds of dogs. Attractiveness is low on the list after considering temperament, size, energy, disposition and human needs.

For instance, there are those who prefer large dogs, but live in apartments. That sounds prohibitive, but may work out fine if they choose the appropriate breed. A St. Bernard may not be recommended, but a Labrador may work out due to some of their common personality traits. Another example might be that of an elderly person who thinks that Border Collies are beautiful and wants one badly. Now, if that elderly person is still active and ready to provide ample opportunities for a Border to run and exercise, that match may well work out. However, anyone who must spend most of their time in the home should probably consider a dog who is happy to curl up on a blanket and watch TV or take short walks to the corner.

There are many Web sites available that provide information regarding breed characteristics: www.petfinders.com is one of them. Some breeds require more grooming than others — and while many owners do their own dog grooming, others must use a groomer, which is an added expense. Other breeds may need veterinary attention more than others, which is also an expense an owner must anticipate. Using common sense in making such an important decision is essential. If you don't have a computer, there is an abundance of information at the library. There's nothing more important than adding the appropriate companion to your home.
