Many people will give some excuse not to keep a pet: They smell bad, they are messy, they are expensive, or I don't have enough time to take care of them. While most of these reasons sound plausible, there are some good reasons why you should keep a pet to have a positive life.
First, pets can give you unconditional love and companionship. Pets make you always feel accepted and loved. They are always good listeners and respond to love, regardless of whether you are blind, deaf, ill or depressed. When coming home from a long, stressful day of school or work, you see a cute animal waiting for you in front of the door. You can't help but feel happy!
In addition to companionship, pets can greatly increase your physical activity and improve your overall state of health. It is proven that a person who owns a pet is less likely to struggle with ailments and serious medical problems. Owning a pet can help people lower the blood pressure, fight loneliness, and conquer depression. Long walks with a dog also burn your calories!
Undoubtedly, keeping pets makes you busier and leaves you more work to do.
