I agree, my uncle is a real stickler when it comes to age. He said if you going to take a peak at them, least wait until they are 2 years old to see if they are interested. If so take a look and see what you have but never give a pup a grown dogs test. If you want him to show the ultimate signs of maturity, then allow him to mature. He knows it may be a few exceptions but most dogs in his opinion shouldn't see a test until they are 3.
