Bilingual Benefits. Can My Dog Understand Two Languages?

The Growing Trend of Bilingual Pet Owners

With increasing diversity and multiculturalism, more pet owners are speaking to their furry friends in multiple languages. According to research, Hispanic and African American pet ownership is on the rise, with multicultural pet owners spending 22-37% more on average on their pets (source). As the demographics of pet owners evolve, bilingual communication with pets is becoming more common.

Training your dog in two or more languages has many benefits, including improved bonding, enhanced cognitive development, and better behavior. However, it also poses some unique challenges. In this article, we’ll explore the world of bilingual dog training and provide tips and strategies for owners looking to bridge the language gap with their furry friends.

Dogs Can Learn Multiple Language Commands

Research shows that dogs have the cognitive ability to learn verbal commands in multiple languages. Dogs can discriminate between different languages and do not just respond to auditory cues, but understand the meaning behind words in different languages (1). For example, studies have found that dogs respond correctly to commands in both English and Spanish or English and Japanese when trained using both languages (2).

Dogs can learn similar verbal commands across languages like “sit,” “lie down,” “stay,” and “come” because they associate the different words with the same actions. With consistent training methods, dogs are able to build an understanding of what the verbal cues mean in each language. Their brains can process the different phonetic sounds across languages for commands they already know (3).

Evidence of dogs’ capacity for learning multi-language verbal commands can be seen in many police dogs, military dogs, service dogs, and dogs trained for dog sports. These dogs often need to respond to handlers who speak different languages and are able to be trained successfully in multiple verbal command languages.



Challenges of Two-Language Training

While dogs have an impressive ability to learn verbal commands in multiple languages, training a dog in two languages can also come with some challenges that need to be managed. One potential issue is confusion from similar sounding commands in the two languages. For example, “sit” in English sounds very similar to “sitz” in German, which both mean the same thing. If not trained properly, the dog may get confused and not respond reliably.

Another challenge with two-language training is the need for consistency. According to experts, it’s best if each handler consistently uses only one language when giving commands. If multiple people are training the dog and frequently switching between languages, this can lead to confusion and lack of consistency for the dog. The dog needs repeated exposure and reinforcement using each command in the proper context to learn them effectively.

The key to success is to have a consistent approach when using the two languages during training. Each handler should choose one language and stick with it to avoid confusion. It also helps to use very different words for similar commands in each language. With patience and proper technique, dogs can definitely learn verbal cues in multiple languages.

As an example, one study from Reddit showed a dog successfully learning commands in both Spanish and English without issues when the training was done consistently by each handler.

Tips for Two-Language Training

Teaching a dog commands in two languages takes dedication, but it can be done. Here are some tips to help make two-language training successful (Source:

Use unique words for key commands in each language. For example, “sit” could be “sientate” in Spanish. This helps avoid confusion between the two languages.

Attach visual cues to commands. For example, use a hand signal along with each verbal command. This strengthens the dog’s understanding.

Keep early training sessions short, around 5-10 minutes. This prevents the dog from becoming overwhelmed while learning new commands.

Be patient and consistent. Stick to one language per training session. With time and practice, the dog will learn to distinguish between the languages.

Reward and praise the dog generously when they respond to commands correctly. This positive reinforcement is key for bilingual training success.

When to Start Two-Language Training

The best time to introduce a dog to two languages is when they are still a puppy. Puppies have eager minds and can easily absorb multiple verbal cues. Starting two-language training early takes advantage of a puppy’s natural ability to learn new things quickly.

However, it is certainly possible to train an adult dog in two languages as well. While puppies may pick up new verbal cues more readily, adult dogs can still learn multiple languages with consistent, positive training methods. The key is to have patience and reinforce commands in both languages through repetition and reward.

According to dog training experts, the ideal time to start teaching a second language is around 3-4 months of age. At this point, puppies have mastered some basic training and are ready for new verbal challenges. Of course, any training should be age-appropriate and begin with simple, frequently used commands.

So in summary, starting two-language training with a young puppy capitalizes on their youthful ability to absorb new information. But adult dogs can become bilingual too with time, consistency, and encouragement. The most important thing is to make training fun and rewarding.

Examples of Successful Bilingual Dog Training

There are many anecdotes of dogs who have become skilled in understanding commands in two different languages. According to a study reported on by NPR, dogs trained using both English and Spanish commands were able to distinguish between the two languages when tested in an fMRI scanner.

The study found a 9-year-old border collie named Bunny, who understood commands in both Spanish and English, showed distinct neural patterns for each language. This suggests dogs are capable of separating and understanding different languages.

There are also many stories of owners who have successfully trained their dogs in multiple languages through consistent training. For example, some military and service dog handlers use both English and hand signals to train dogs for optimal obedience. Additionally, dogs adopted overseas often learn new commands in their adopted family’s primary language.

With proper training techniques, positive reinforcement, and consistent exposure, evidence shows dogs have the cognitive capability to learn verbal and physical commands in multiple languages. Their ability to distinguish languages is an impressive demonstration of canine intelligence and adaptability.

The Cognitive Benefits of Bilingual Training

Teaching your dog commands in two languages provides mental stimulation and enhances their learning and memory. When dogs learn new words and commands, it activates their brains as they work to comprehend the meaning of each word and distinguish between the two languages. According to a study by Cell, bilingual humans show increased gray matter density in the left inferior parietal cortex region of the brain which controls learning capacity. While formal studies have not been conducted on bilingual dogs’ brains, it is reasonable to hypothesize similar cognitive benefits.

Learning a second language forces the brain to work harder as it must inhibit one language while using the other. This cognitive flexibility then transfers to other learning and problem solving tasks. According to Leon Valley Veterinary Clinic, bilingual dog training provides mental enrichment that can aid older dogs or breeds prone to cognitive decline. The mental stimulation can help keep them sharp and engaged with their training.

Two Languages Can Strengthen the Human-Dog Bond

Speaking two languages with your dog can actually help reinforce and strengthen your relationship. As with any relationship, communication is key. The more you communicate with your dog in a positive and consistent way, the stronger your bond will become over time.

Learning commands in two languages requires dogs to pay close attention to their human companions. It promotes focus, engagement, and connection. According to the Human-Canine Bond website, the history of the human-canine bond can be traced back over 15,000 years [1]. This longstanding partnership thrives on communication, responsibility, and companionship from both parties.

Providing mental stimulation through bilingual training challenges your dog cognitively and also adds variety to your daily routine. This shared learning experience provides mutual benefits for both dog and human. As your dog masters new skills, your bond continues to grow. Consistent two-language training reinforces the unique friendship, loyalty, and symbiotic relationship humans share with “man’s best friend.”

Overcoming Challenges of Two-Language Training

Training your dog to understand commands in two different languages can be challenging, but it is achievable with consistency, patience, positive reinforcement, and time. Some of the keys to success are:

Patience is key – Don’t expect your dog to immediately understand and respond to commands in a new language. Just like people, dogs need repetition and time to get used to new words. Be prepared for some initial confusion and errors.

Be consistent – Stick to one word for each command across both languages. Don’t confuse your dog by using different words for the same command. Consistency will help your dog learn faster.

Use treats and praise – Positive reinforcement is crucial when training in two languages. Reward your dog with treats and verbal praise every time they correctly respond to a command in either language. This will motivate them to keep learning.

With regular short training sessions, patience, and positive reinforcement, you can teach your dog to be bilingual. The extra effort will lead to an even stronger bond and better behaved canine companion.


By training your dog in two languages, you can strengthen communication, reinforce training, and provide mental enrichment. While it requires extra effort, being fluent in two languages helps dogs focus and adapt, forges a closer bond, and lays the foundation for ongoing learning. To develop successful bilingual skills, be patient, use short and clear verbal cues, practice separately, and reward good responses. With time and consistency in both languages, you’ll be amazed by your dog’s ability to switch between languages seamlessly. The intellectual and relational benefits make bilingual training well worth the initial challenges for both you and your dog.

The key is not giving up when it gets difficult. Be creative, stick to the training basics, and tap into your dog’s eagerness to work with you. With the tips provided here, you can achieve two-language fluency and enjoy a deeper relationship with your dog.
