I have found that most pointing dogs have a natural retrieving instinct. The key is to nurture this without burning them out on retrieving. Especially if you have kids helping you train young dogs. I think 3-4 tosses of the dummy or knotted up sock are the maximum. You can tell in the second video below that Lucy is starting to lose interest (her 4th retrieve of this short session). When I see the puppy start to lose interest I put it away for the day and move on to something else.
As your puppy gets a little older and wants to go away from you rather than bring it right back, there are a couple things you can try. One is to throw the dummy in and enclosed area where they can’t go anywhere. The other idea is to use a lead and coax them back in gently with the here command. Both ways have worked for me in the past. But, if you keep the session short (2-3 throws) your puppy will usually be glad to bring it right back. The key is to keep it positive, have fun and try to end on a positive not. End the session before they get bored, that way they will be hungry for more.
