Pups don't always point with the intensity of an older dog. A point with a flagging tail and a puzzled expression is still probably a point. Walk in front of the dog without delaying. Don't run--it's not safe and it can spook birds--but don't tiptoe either. Rather than approach from directly behind, come in from three or four steps to the side. From that vantage, you'll be able to see where the dog is looking, which is usually at the source of the scent. Try not to get between the dog and the bird, or your puppy may break and bump your quarry.
