Choosing a Dog Breed is important to get right. Size characteristics such as how tall or how much a breed weighs will depend greatly on the size of your home. How much exercise you can provide your dog should also be factored in when determining which dog breed is right for you. If you have small kids then it is important to research which dog breeds are best for small children. Hypoallergenic dog breeds for allergy sufferers should also be considered for people who are allergic to dog hair.
