There is a staggering amount of evidence to suggest that being a dog owner can lead to multiple health benefits. They are famously known to improve your cardiovascular condition and decrease chances of heart attacks. Playing with a dog can also elevate levels of serotonin and dopamine in your body, helping you stay calm and relaxed.
Caring for your dog is a two-way street. They are acutely aware of the people who love them, and in most situations behave very intelligently when it comes to protecting them. If you are an intruder and you see a dog trying to protect its master, then you better be scared, because that loving animal values its master’s life more than its own.
