Dogs are a joy to be around and they can make you laugh with their cute antics. They are a good companion for humans and help in lowering anxiety and blood pressure. They also keep you active and increase social functioning and mental capabilities. They are also excellent at protecting their owners and can be a great alarm system, as they bark and yelp when there is a stranger around the house.
They are used by the law enforcement as a sniffer and help people in search and rescue operations. They can also detect disease and drugs and are often used for tracking. They are able to communicate with their humans through body language, odors and other signals and can also understand around 165 words. They can also be trained to act as living blankets and even be used to carry loads for their masters.
The dog is a very versatile animal and can adapt to many different environments, which makes them a popular choice as a pet. They are often portrayed as being faithful, protective and loving and can be the ideal partner for humans. They have a strong sense of loyalty and are great companions for children, the elderly or even for someone suffering from mental illnesses.
