With National Mutt Day just around the corner on July 31, it’s the perfect time to explore our favorite mixed-breed companions. A mutt is a dog of mixed or unknown breed heritage, and there’s a common belief that mutts are healthier due to “hybrid vigor.” Hybrid vigor is the improved health of offspring due to the mixing of parental genetic traits. But how true is this claim? I’ll try to answer that question in today’s blogpost.

If dogs have a flaw, and I realize many would argue they do not, it is they don’t live long enough. I think many would agree that a dog lifespan of 40 or 50 years would be perfect, so that you could have the same best buddy for your entire adult life. In the past few weeks, there have been two interesting scientific publications on longevity in dogs. The studies’ conclusions and impact on your dog will be the topic of this blogpost.
