How to choose the right breed of dog
Consider a breed's size.
Dog size can play an important role in deciding which breed is right for you. Size is most important to consider in relation to your living environment.
A dog's size can determine how comfortable they will be in your home and how much space they will need to be comfortable. A general rule is that large dogs need more space and smaller dogs need less, but there are exceptions depending on temperament and energy levels.
