Dogs are often referred to as man’s best friend, and many pet owners are of the opinion that their dogs understand everything that is said to them. Dogs seem to understand everything that their owners say, from simple words like “sit” and “come” to complex words like “I love you.” The question that comes to mind here is whether dogs really understand what their owners say or whether they are simply responding to the sounds and gestures that accompany the words. The answer lies somewhere in between, say the experts.



Dogs can learn words, but not like humans




Studies have proven that dogs are able to learn the meanings of the words that are frequently uttered. Some dogs are able to learn the meanings of over 100 words, and in some rare cases, the number of words that dogs are able to learn is even higher. However, dogs are not able to learn the meanings of words like humans do. Dogs are not able to learn the meanings of grammar and sentences, but are able to associate certain sounds with certain actions, objects, or feelings.





For instance, when you say the word “walk,” your dog gets excited because it has learned to associate that word with going outside. When you say the word “food,” your pet runs to the kitchen because it has learned what happens after hearing that word. This demonstrates that dogs understand meaning by repetition.



Dogs pay more attention to tone than words



One of the biggest reasons why dogs appear to understand us so well is that they pay close attention to our tone of voice. Dogs are very sensitive to sounds, and they can easily distinguish between a happy tone, an angry tone, or a sad tone.



For instance, if you say something nice in an angry tone, your dog may react as though you are angry. On the other hand, if you say random words in a cheerful tone, your dog may wag its tail because it thinks you are happy.




Dogs also read body language



Dogs do not just hear what you say. They actually hear body language more clearly than what you say. They observe your facial expressions, hand movements, postures, and even your walking style.



If you hold your leash in your hands, your dog knows that you are going out. You do not even need to say anything. If you sit down quietly and look sad, your dog will come closer to you. This is because dogs were created to stay with humans. They observe human behavior very well.



Can dogs understand feelings?



Experts believe that dogs can understand human feelings. It has been proven that dogs behave differently if their owners cry, laugh, or seem stressed. Some dogs even try to console their owners if they seem sad.



Although dogs do not hear what you say if you are sad, they do understand that something is wrong. This is why the relationship between humans and dogs is so strong.




The smartest dogs understand more words



There are certain dog breeds that tend to learn words faster than others. For instance, Border Collies, Poodles, German Shepherds, and Golden Retrievers are considered to be among the most intelligent dog breeds. They tend to memorize many words.



There have been instances when dogs, after being trained, could recognize toys by their names, respond to complex commands, and even pick items when asked. This proves that dogs can learn much more than we think.



Why it feels like dogs understand everything



It sometimes feels like our dogs understand everything. This is because dogs tend to learn patterns. They tend to hear certain words in one context repeatedly. They learn to associate these words with certain outcomes.



For instance, if you usually say, “Let’s go outside,” your dog might react even when you say, “Let’s go.” They tend to anticipate the rest of the sentence. Dogs, after a while, tend to be very good at anticipating our actions.
