There is nothing worse than playing fetch with your pup and he won't drop the toy once he brings it back to you. That is unless you have a dog with a slipper fetish--then nothing is worse than soggy slippers. Training your dog to drop an item is not as hard as you might think, it just takes a little time and patience. The last thing you want to do is chase him around endlessly. Not only is this futile, but your pup will simply think you are playing a game.
In fact, the more you chase him and the louder you yell, the faster your pup is likely to run away from you. A much better solution to the problem, one that will make everyone happy (except for maybe your pup who will miss the game) is to simply teach him to drop items on demand. This is a very important command, as it will be useful in many other tricks you can teach your dog down the road.
The task is simple: your mission (should you choose to accept it) is to train your dog to release anything he has in his mouth into your hand when you tell him to. This is a very important action to train your dog as it may stop him from getting hurt if he picks up something he shouldn't and it lets him play a number of games such as fetch or tug of war without anyone getting hurt.
The command is very simple, most people tend to use the two words "Drop it!" in a strong and commanding voice without yelling. In fact, the last thing you want to do is yell at your dog as this can turn the whole thing into a game, one that can be hard to overcome. While you can teach any age dog this simple command, it is one you really need to teach your pup at an early age. In most cases, you can teach this trick to your dog within a few days. Remember to work in short sessions of around 15 minutes several times a day. Be sure to give him plenty of praise and rewards when he does what he is told.
Like any good training program, there are a number of things you will need to successfully train your pup to drop an object. Among these are:
