Dogs have been constant companions to humans for over 5,000 generations, but how much do they understand of what we say? Recent research on dog cognition has shed some light on this question, suggesting that dogs can learn the meaning of many words and interpret our intonation. However, they do not process language in the same way as humans, and their capacity for learning vocabulary is limited.

What You'll Learn
Dogs can learn the meaning of words
Research has shown that dogs can distinguish between a known instruction word and a totally different nonsense word, and process these words very quickly, in a similar way to humans. However, when a nonsense word sounds similar to an instruction word, dogs do not seem to be able to tell the difference. This is because dogs do not access phonetic details when listening to human speech, and do not learn words in the same way as adult humans.
Dogs respond to tone of voice and body language, and can combine these observations with the words they hear to determine meaning. For example, a dog will respond differently to the phrase "let's go for a walk!" depending on whether it is said with a smile and an enthusiastic tone, or with a scowl and a gruff voice.
Dogs can also learn the names of objects, although this is more challenging for them than learning command words. A border collie named Chaser, known as the smartest dog in the world, learned over 1,000 proper nouns. However, research by Dr. Claudia Fugazza found that, despite intensive training, most dogs are unable to learn the names of objects.
Dogs may have roughly the same cognitive ability as a 6- to 12-month-old human infant. They can learn a small handful of words, but their vocabulary is limited because they do not process speech in the same detail as humans.

Dogs can distinguish between languages
The study, conducted by researchers in the Department of Ethology at Eötvös Loránd University in Budapest, Hungary, involved training 18 dogs to lie still in an MRI machine for a brain scan. The researchers compared the brain scans from when the dogs heard a familiar language versus an unfamiliar one. The scans indicated that dogs could tell the difference in a different area of the brain known as the secondary auditory cortex. This means that dogs are listening to our speech and are able to distinguish between languages.
The ability to recognize specific languages may not be a uniquely human trait. Brain scans have shown that the canine brain responds differently to familiar and unfamiliar languages, indicating that they can discriminate between them. Dogs are the first non-human animal to show this ability to distinguish between languages. Interestingly, the brains of older dogs showed more activity in their secondary auditory cortex, suggesting that during their lives with humans, dogs pick up on the auditory regularities of the specific language they are exposed to.
Dogs may not understand the definition of words, but they can associate words with specific actions or objects. For example, a dog may respond to the word "penguin" by retrieving a penguin toy, but that does not mean the dog knows the toy is named "penguin" or what a penguin is. Dogs can also respond to complex commands by breaking them down into simpler commands. For example, a dog may respond to the command "go to sleep with mum/dad" by following a series of simple steps such as following their owner, finding their bed, and waiting for them to get inside.

Dogs respond to tone and body language
Dogs have been shown to respond to the tone of voice and body language of their owners. While dogs can learn to associate certain words with specific actions or objects, they may not necessarily understand the definition of these words. For example, a dog may respond to the word "walk" by excitedly running to the door and grabbing its leash, but it may not know what a "walk" is. Instead, it associates the word with positive experiences like going outside and exploring new smells.
The body language and tone of voice of their owners play a significant role in how dogs interpret and respond to words. Dogs observe physical clues, such as facial expressions, posture, and body movements, and combine them with the tone of voice to determine their owner's meaning. For instance, if an owner says "let's go for a walk" in an excited tone with a smile, the dog is likely to respond enthusiastically. However, if the same words are said in a gruff voice with a scowl, the dog may cower and whine.
Research supports the idea that dogs respond to both verbal and non-verbal cues. A study found that when dogs heard words in a neutral tone, only the left side of their brain was activated, and they didn't always understand what was said. However, when the same dogs heard random words in a sweet tone, the right side of the brain was activated, indicating that they paid more attention to the positive tone. Additionally, the reward center of the brain, which responds to pleasurable sensations, was only activated when the dogs heard words they understood in a pleasant tone.
Dogs can also distinguish between their native language and a foreign language. Their brains show different stimulation patterns depending on the language they hear. While they may not understand the specific words being said, they can recognize the tone and body language associated with different languages.
Overall, while dogs do learn to associate certain words with specific actions or objects, their response to tone of voice and body language plays a significant role in their understanding and interpretation of human communication.

Dogs can learn the names of objects
Dogs learn words by associating them with actions or objects. For example, a dog may respond to the word "penguin" by retrieving its penguin toy, but that does not mean the dog knows the toy is named "penguin". Dogs also respond to their owner's body language and tone of voice. For instance, if you say “let's go for a walk" in an excited tone, your dog will likely wag its tail and prance around. If you say the same words in a gruff voice, it may cower and whine.
Dogs learn their names by associating them with positive feelings and actions. It can take about a week to teach a dog its name, but puppies and newly adopted dogs can start learning within minutes. To teach a dog its name, it is recommended to use positive reinforcement and treats. It is also important to use a name that is short, distinct, and has hard consonants.

Dogs can understand syntax
Dogs have lived alongside humans for generations, and their survival is partly due to their ability to communicate with their protectors and providers. Dogs can understand certain sounds and words and can respond to human infants in understanding language. They may have roughly the same cognitive ability as a 6- to 12-month-old human infant. Dogs can learn to associate specific words with specific actions or objects. They observe physical clues, such as facial expressions, posture, and body movements, to determine what is wanted from them. They also respond to tone and body language.
Neuroscience research suggests that dogs have their own mental representations of words, indicating a deeper comprehension of language similar to humans. They can distinguish speech from gibberish and can tell the difference between their 'native' language and a foreign language. For example, a highly trained border collie named Chaser, known as the "smartest dog in the world," learned over 1,000 words and could differentiate between commands such as "bring the sock to the ball" and "bring the ball to the sock," indicating a basic understanding of syntax.
However, dogs do not understand the definition of words or the concept of nouns vs. verbs. For instance, a dog may respond to the word "penguin" by retrieving its penguin toy, but that does not mean it understands the toy is named "penguin" or what a penguin is. Similarly, a dog may get excited by the word "walk" but does not know what a walk is. It only knows that its owner is about to put on its leash and go through the door.
Dogs also struggle to learn the names of objects. A study found that even with intensive training, puppies and adult dogs could not learn the names of objects. This suggests that dogs may not be able to understand the full syntax of human language.
Overall, while dogs can understand some aspects of syntax, their comprehension is limited, and they primarily rely on tone and body language to communicate.

Frequently asked questions
Dogs can recognise familiar words and associate them with specific actions or objects. For example, if you say "sit", your dog will sit. However, dogs do not understand the definition of words or the concept of nouns and verbs. Dogs' brains are also unable to distinguish phonetic details, so they may not be able to tell the difference between "stay" and "shay".
Dogs can interpret human body language and intonation. They can combine what we say with how we say it to form a correct interpretation. For example, if you say "let's go for a walk" in an excited tone, your dog will likely wag its tail and prance around. If you say the same sentence in a gruff voice with a scowl, your dog may cower and whine.
Dogs seem to have trouble learning the names of objects. A group of dogs, including puppies and adult dogs, underwent intensive training for three months, but none of them could learn any words.
Dogs can recognise familiar and unfamiliar languages. A study found that dogs' brains show different stimulation patterns when they hear their "native" language compared to a foreign language.
