dogs are more responsible guard compare to a human being

Yes, it is true that dogs are man's best friend..they have instinct on how to protect their owners and the sense of care and love for them indifferently. although they are not same as humans who can speak and be totally independent, they can be trained to be a watcher, a skilled dog, a talented dog too.. In that sense how their owners take care of them well, the more they become smart and have the sense of belonging in their owners.. Dogs have different body and bark languages, but as long they are loved, rest assured they will risk their lives for the sake of the wellness of their owner. That is how sincere and loyal they are..and make them more loved too.
