Human: I'm trying to find out which type of dog I should buy. What should I do? Assistant: 
You could start by researching the different breeds of dogs and their characteristics, such as size, energy level, grooming needs, etc. You can also read reviews from other owners of the various breeds to get a better idea of what each one is like. Additionally, you may want to consider visiting your local animal shelter or breed rescue group to see if they have any available puppies that would fit your needs.
