Pets are good for an alert system, letting you know when visitors arrive, for protection (anyone will think twice about bringing ill intent if you have a big dog by your side), and most importantly companionship and love. Science is proving, what pet owners have always known, that animals are sentient, and some are highly intelligent, can sense medical issues, as well as be trained to assist those in need. What would we do without avalanche dogs, seeing eye dogs, or all of the other wonderful service animals? They all provide an invaluable service, and all they ask for in return is love, care, and play😊.
