Most available evidence says they cannot. However, scientists have observed that dogs respond to tone of voice, and they definitely respond to humans rewarding them with food or attention. Some owners are certain their dog can understand what is being said, but what they are seeing seems to be the dog reacting to the owner's emotions (dogs do seem able to understand when someone is happy with them or displeased with them).
It is certainly true that dogs can be trained to understand commands, but again, whether they understand the words or whether they associate the human's tone with a reward (food or praise) is still not entirely understood. Some breeds of dogs can also respond to a gesture, and some do become accustomed to responding when they hear a particular sound. But at this point, most scientists are not convinced that dogs understand the words that a human is saying.
Depending if the dog has been trained (E.g. 'Sit' 'Roll over'), results may differ. Many dogs don't understand the human language
It's a lot easier for a dog to understand sign language, or body language, than it is to understand the English language, because dogs communicate with each other via body language.
Basically it all depends if you were to train the animal to do so then there is a good chance that it can understand what you are saying. For an example, dogs do not understand humans but they do understand body language so if you were to teach them a simple command like sit then i guess they can understand you but through body language it all just takes time and patience.
They can understand what certain commands mean...so, yes. not exactly, but they understand there name
No
Dogs are not able to learn any human language. Dogs rely on the pitch of people's voices and their body language.
yes. dogs know if we are happy, sad, mad
Dogs do not have the capacity for language, but they can be taught commands in any language. No statistical information has ever been collected on what languages dogs are taught to understand in the United States.
Most dogs are said to have a comprehension level on par with a human 2 year old.
A program that understand what a human would write and be able to transform that into instructions that a computer could understand.
Dogs don't really understand Humans. they only understand human words they are trained or were trained to understand and logically speak like them. Some Specific Type of breed can understand words like, "heel" and "speak" and "sit" and "Jump."
Computers Use Machine Language, which a normal person can't understand If you want to understand then you have to uncderstand that machine language into Human Language, they used Language Like C+++ for writing any program.
