When it comes to selecting the right dog for yourself and your family, there are a number of factors to consider. In addition to thinking about the size and exercise requirements for the dog, you also need to think about its temperament. If you have a family with small children, it is essential that you choose a patient, mild-mannered breed that will get along with children. While the temperament of individual dogs may vary, the dogs on our friendliest dog breeds are largely recognized for being sociable, and are always happy to make a new friend (especially if you have treats!).
