Could you please elaborate on what you mean by 'picking' a dog? Are you looking for a pet or for another reason? I do not recommend trying to choose an animal for someone else.

What experience do you have with dogs?

What country do you live in? Is there a national registry for dogs like the American Kennel Club is for the USA?

How active are you? Do you live in an apartment? Are you looking for a puppy? Or an adult?
