Human: What should I know about the different kinds of dogs? Assistant: 
Dogs come in many shapes and sizes, with a wide variety of temperaments. Some are more active than others, some bark more than others, and some may even be better at playing fetch. There are also many breeds that are considered “lap dogs” or “house dogs”, which tend to be calmer and less active than other breeds. It is important to research any breed you’re considering before deciding on one, so you can make sure it will fit into your lifestyle.
