Can pets help reduce anxiety, stress or depression in humans? You bet. If you've ever walked into your home after a bad day only to be welcomed by a wagging tail, you get it.

Ian Cook, MD, a psychiatrist and director of the Depression Research and Clinic Program at UCLA had this to say, "Pets offer an unconditional love that can be very helpful to people with depression."

Studies have found that animals have the ability to reduce tension in humans, while improving their overall mood. The next time you're feeling blue, you may find that spending time with animals will help.

Ways that Animals Help Us

Pets, such as dogs and cats offer unconditional love. They don't care if you look rough or gained 20 pounds. All they want is affection and to spend time with you. You don't have to worry about unsolicited advice or hurting their feelings.

If you're depressed, taking care of yourself may be difficult, but sometimes the added responsibility of having to care for your pet is just what you need. Knowing that someone else is relying on you gives you a sense of value and importance.

Have you been spending more time on the couch than outside? You need ample physical activity and having a dog that needs to be walked can be exactly what you need. A walk gets you fresh air, and it can naturally improve your mood.

If you're feeling isolated, a pet can offer companionship. When you have a pet who loves you unconditionally, you're never alone and that makes all the difference. Dogs are also great icebreakers so talking your dog on walks or to the dog park can help you meet other animal lovers.

If you get a new pet, be sure to take him or her to a veterinarian for a checkup!
