Dogs are great companions. They’re by your side for all of life’s little moments -- their head buried in your lap while you watch tv, their excited yelp from the back seat of the car when they realize you’re almost at the dog park. But dogs are only able to share their lives with us for a short time. That’s why the health of your pet is an important consideration. Like a human, a dog needs to follow a healthy diet, get regular visits to the veterinarian, go for the occasional run, and even have health insurance. While this will help you make your dog's life a little happier, maybe a little longer, it's not the fountain of youth. You are still likely to outlive your furry friend.
