As someone who loves dogs, I have been thinking a lot lately about getting one of my own. My parents have had a dog for the past five years (a lively, loyal, and very friendly Wheaton Terrier named Freddie), and even though I don't live with them anymore, I still consider him part of the family and love getting to see him when I visit home. Many residents at my apartment complex have dogs, so I get to see them walking around the parking lot and courtyard on a regular basis.

Although I'm currently not in a life situation where I can get a dog (financially, time commitment, and my living situation) I'm very excited to get one in a few years. I have even looked around some at breeds that I might be interested in. I really just love dogs and whenever I see an adorable labrador puppy or a handsome German shepherd, it makes me excited to get the first dog of my own.

There have even been studies done and surveys taken about the psychological and emotional benefits of having a pet. So if you're not already a dog lover like me, you might still want to consider getting one - it will probably be a very positive addition to your life! Here are my top five reasons to have a dog:

1. It's fun! Playing with a cute, happy dog and having a constantly loyal companion is great. You know how some people say that the simple things in life are the best? I think ALL dogs would agree with that. Well, it's probably because dogs' lives are more simple than humans. But just think: a dog gets so excited and happy about the littlest things - seeing his or her owner (even if you've only left for 5 minutes), eating (even if it's dog food), going outside, hearing another dog bark, etc. Having a pet around who is constantly excited about the simplest pleasures in life can make you appreciate these things as well.

2. They're great company. You're greeted exuberantly every time you come home and worshipped like a king when the dog wants to eat. A dog can also improve your mood and overall sense of well-being. Studies have even shown that people who own pets are less likely to suffer from depression and more likely to have good emotional health.

3. They can help you stay fit. Since dogs require daily exercise (some breeds certainly need more than others), it gives the owner an excuse to take long walks or even runs. If your dog is well enough trained, you can even take him or her to a park and run around, playing fetch or another game. Since dogs generally love to run around and be active, it may inspire you to be more active as well.

4. Have something to care for. Particularly for the elderly, having a pet to care for can provide a meaningful everyday purpose to people who aren't very busy. Since dogs often demand a good amount of work - taking them on walks, cleaning up after them, grooming them, bathing them, feeding them, etc. - it can actually provide some people with a desirable degree of responsibility for someone besides just themselves.

5. They will always love you! Dogs are so often called "man's best friend." I can't think of another creature, besides humans (and not all humans are this way), who will love you unconditionally, remain loyal to you no matter what and sometimes even risk their lives to save you. I always smile when I hear stories of dogs who selflessly put themselves in harm's way to defend their owners.
