What are the advantages and disadvantages of keeping a dog?

Keeping a dog can reduce the pressure on the owner, help the child grow up and reduce the risk of illness.

Scientific research has proved that dogs can effectively lower the blood pressure of their owners, and children who like pets will do better in cognition, socialization and sports. After one month of keeping dogs and cats for the elderly, minor ailments, such as joint pain, hay fever, insomnia, constipation, anxiety, indigestion, cold, dyspnea and headache, were alleviated by 5%.

When the owner touches the dog, it will shut down the pain processing center of the brain, which means that it will relieve the owner's pain and anxiety without side effects.
