For example, you can pick out two Labradors where one is super crazy and needs constant action and strict training and another that is super chill and is super easy to work with as it will only want to please you. However, certain generic characteristics will apply to both. If you adopt, then make sure you know what you are getting (though this is a bit of a surprise bag usually). Especically when adopting at young age, the dog might change over time and calm down. There are certainly certain breeds that are generally not recommended to beginners.
