Hmmmm which breed? WILL CHOOSE BEST?

You can do your best to find a breed that works for you but if you are buying a puppy you can't truly know how their personality will develop. When I chose my puppy I picked the most lowkey, least dominant one I could find from the litter. Now, at 8 months he is very bullheaded and hyper. I don't mind because I love him so much but if you know these are not personality traits you want to deal with I suggest buying an adult dog (possibly from a shelter) so that you know exactly what you are getting and can find the best fit for you. Also, if there is a breed you have in mind you could try a rescue, they are generally very good about matching you with a dog that fits your needs.
