Dogs can be taught commands in any language. If you would like to train your dog with Dutch commands, the first thing you will need to know are the commands your dog will learn. You can choose to only speak to your dog in Dutch or you can make him bilingual by training commands in English and Dutch back-to-back or simultaneously. If you would like, your dog can listen to you and his new Dutch commands while other dogs around him will be unable to interfere or perform the trick as well because they may not know the language as your pup does.
Imagine being in a busy place such as your veterinarian's office or even a dog park and giving commands to your dog in Dutch. He won't be distracted by other dogs doing the same tricks because he may be the only dog who understands what you're asking him to do.
Training a dog in Dutch commands is not much different than training your dog using English commands. Your dog will perform tricks and put himself in positions by the command as long as you are training him to do so. Just as you do with English commands, training your dog using Dutch commands will require some patience, scheduled training time, and an idea of what your dog should be doing. Bilingual or foreign language training will condition your dog as you repeat commands and reward for good behavior.
You can train a dog at any age commands in Dutch or any other language. Puppies are fast learners and absorb information quickly. If your dog already knows English commands, it may take a little extra time to retrain the same tricks using a different command.
Your dog will require lots of tasty treats and some excitement during training sessions. If your little guy already knows English commands and you would like him to know Dutch commands as well, be prepared to retrain the same commands in a different language. If you are teaching your puppy obedience commands for the first time and doing so only in Dutch, you will need quiet training time, treats, and a familiarity with the Dutch commands you want to use.
