I developed a clicker retrieve based on one I found online by Shirley Chong, with some adjustments for Schutzhund and have continued to develop it based on the dogs I have trained this way. Originally I was "challenged" by a friend of mine - "I won't believe a clicker retrieve is any good unless the dog can be suspended off the floor holding the dumbell!" - so off I went to prove I could achieve this with my first dog Bodeus.
The entire playlist of videos for the clicker retrieve is available on my youtube channel including newer videos just added, click here.
First, find a dumbbell the appropriate size for your dog or puppy. Starting with something smaller and lighter than a SchH1 dumbbell will help to increase the speed of learning for a small dog or pup. I wrap the bar of my dumbbells in Vet-Wrap so that the dog has something he can push his teeth into as this encourages a strong grip on the dumbbell. Another option is to start with a straight dowel if you are beginning with the hold exercise, you can then also use PVC and even a metal pipe to generalize the hold behavior. It is fine to do extra work on the hold in front, but the initial pick up is also important for the complete retrieve.
I do not do any drive work with the dumbbell before I start - the goal at this stage is to get the dog to think about what is being trained rather than to perform the exercise in drive. The reward at this point is the food, not the dumbbell itself. This is particularly effective when training possessive dogs which will not want to bring the dumbbell back if they think it is a toy (much less give it up voluntarily).
To begin with, place the dumbbell on the ground, while the dog watches, making sure you have your clicker ready. Your dog will probably look towards the movement, and you can click him very quickly. Walk back towards the dumbbell and watch to see if the dog looks at it. At this point, any dog that has been trained to target or articles, will probably go straight back to the dumbbell. You can reward him for either a look or touch. Try to keep the rewards close together so that the dog gets lots of successful repetitions in close succession. In effect, what you are training is that the dumbbell is a very important item.
Watch for your dog getting tired. 5 to 10 successful repetitions are plenty at this point. Often you will see the behavior start to change, the dog will look, then may take a couple of steps towards the dumbbell, if by the 5-10th repetition, he walks all the way up to it by himself, click, and give him the rest of his dinner. This "jackpot" is useful to mark the large steps towards the behavior you are training.
The Youtube video above shows Banshee and Bella at 6½ months. This is the first session of a clicker retrieve, both pups have completed article indication, so they know to interact with the item. You can see Banshee offers the article indication down, so I only click when she touches the dumbell.
Depending on the dog, having the dog go up to the dumbbell and touch it with his nose should take 2-10 sessions. Dogs with previous targeting experience often are doing this in the first session. Next when the dog has gone out to the dumbbell reliably for at least 2 sessions, we start to ask for more. Spend a couple more sessions only rewarding the dog for touching the bar of the dumbbell, the ends do not get him a reward. Next we are looking for a more determined bump with the teeth, or lick. If your dog starts to get "stuck", where he spends time offering a behavior he already knows (like sitting in front of you), just move back a step (if he was licking, but is now stuck, go back to rewarding a nose bump or even a look if he is really stuck) for a session or two. I have found it ok to ask for a little more sometimes, and taking a step back does not seem to be detrimental. Obviously your goal is to keep the rate of success very high so the dog does not get stuck, but sometimes it is fun to wait a while and see if your dog will offer anything different.
The Youtube video above shows Banshee and Bella on their fourth session of a clicker retrieve, starting the pick up.
At this stage, your dog will probably be taking the dumbbell in his mouth, and maybe lifting or tossing it in the air. Be very careful not to reward the toss, but click when the dumbbell is in the mouth. Then you can begin to click the dog for picking up the dumbbell and taking a step towards you. Don't expect a sit in front of you, but you can try to catch the dumbbell when you click and the dog releases. This gives him the idea that he is returning the dumbbell to your hand.
The Youtube video above shows Banshee and Bella on their eighth session of a clicker retrieve, continuing the pick up.
To improve the hold, tap the ends of the dumbbell, switch hands, gently try to pull the dumbbell from the dog's mouth. If he drops it at any time, start over. Build the strength of the pull slowly. You are looking for the dog to clamp down and pull down on the dumbbell. I have also found that introducing the heavier Schutzhund dumbbells improves the hold.
The Youtube video above shows Banshee on her fourteenth session of a clicker retrieve, beginning the hold from hand.
The Youtube video above shows Banshee and Bella on sessions 18 to 21 of a clicker retrieve, continuing with the hold. At this point I reward pulling back or down on the dumbell and if her mouth stays on the dumbell.
The Youtube video above shows Banshee and Bella on sessions 25 to 30 of a clicker retrieve, continuing with the hold in front. Occasionally we reward them for a front by itself. We are rewarding for longer, calmer holds, and begin to move our hands.
The Youtube video above shows Banshee and Bella on sessions 35 to 40. We move each hand off the dumbell separately, beginning by just opening our fingers, then moving away from the dumbell. The dog is often more sensitive to the movement of one hand over the other. Then we present the dumbell with one or both hands and start to loosen our hands so the dog starts to take the weight of the dumbell. Then we open the fingers on that hand and then move the hand away. Occasionally the dog will drop the dumbell, no big deal, we just pick it up and try again.
The Youtube video above shows Banshee and Bella on session 42. Now we can introduce different dumbells, the SchH1 dumbell and also the leather utility article.
Once this is going smoothly and you can leave the dog on a sit stay with the dumbbell, move away 10 feet and recall, then you can insist on a straight front, and only reward the straight ones.

Click Retrieves taught at home in one place typically take 6 weeks with 1-2 sessions per day with a dog which has no prior experience with dumbbells. A dog which has had previous experiences may be a little more challenging and require emphasis on different parts of the retrieve they are having problems with. Often, going all the way back to the beginning and proceeding in the same manner as above will help, sometimes you may have to focus specifically on one part - the hold for instance. Many dogs are sensitive about the handlers hands being close to their face, you can begin without the dumbbell, by touching the dog on the neck, clicking and rewarding, then moving your hand up to the muzzle, then work on the hold, get a good solid hold, and do the same exercise with your hands touching the dog's neck and lastly head and muzzle. Even with dogs without previous experience, I introduce a lot of different things while they are holding the dumbbell, including touching their heads and nose, tapping the dumbbell and lifting it while the dog continues to hold.
