If you are looking to teach your dog commands in another language such as Italian, it should be an easy transition. Training your dog with Italian commands isn't much different than training in English, but it will take a little work, especially if she's used to listening for English words.
If you are starting from scratch with a new puppy, you will teach her Italian commands the same way you would teach her in English. You might need to do a little studying beforehand if Italian isn't your first language to learn which terms you want to use as commands. If you take a little time and go step by step, teaching your dog Italian commands won't be too much harder than teaching her in English.
Below you'll find a few different methods for teaching your dog Italian commands for any stage she might be in. Check them out and pick the one that will work best for you. With lots of consistency, your dog will be "fluent" in Italian and you'll have learned something new too.
