July 31 is National Mixed-Breed Dog Day — and while we never need an excuse to celebrate the mutts in our lives, we’re glad for the opportunity to sing their praises. If you don’t already know, a “mutt” is a dog with more than two different breeds in their DNA. Their histories are often unknown, which just means you get to invent a creative story about where they came from.

Right now, there are millions of mixed-breed dogs in shelters across the country waiting for permanent homes. In the spirit of National Mixed-Breed Dogs Day, here are nine reasons why you should consider adopting a mixed-breed dog. If you’re lucky enough to already have a mutt, this list will confirm everything you’ve already been thinking — and then some.

1. Mutts can have fewer genetic health issues than purebreds.

Mixed-breed dogs come from a larger gene pool than purebred pups. Their varied genes make them less susceptible to breed-specific health issues than purebreds. Research has found that mixed breeds are less likely to encounter problems such as spinal diseases, hip dysplasia, certain cancers, knee problems, and heart disease later in life. Of course, canine health issues can never be entirely avoided (keep on top of those vet visits), but mutts tend to be a hardy bunch.

2. They live a long time.

Those strong genetics contribute to increased longevity. Researchers agree that dogs with greater genetic diversity often live longer than breeds with less genetic diversity. Bottom line: When you adopt a mixed breed, you’ll have a best friend for many years to come. 

3. You’ll help raise awareness about adoption.

There are many pathways to bringing home a new pet, and adopting a dog in need from a shelter is an excellent one. Every time someone stops you outside to give your pet a little scratch under the chin, you’ll be able to regale them with the tale of adopting your adorable mixed-breed dog, which might inspire them to go the rescue route, too.

Even if you have a specific breed in mind, it’s worth checking out shelters first. There are hundreds of breed-specific shelters across the United States, specializing in everything from hypoallergenic Goldendoodles to apartment-friendly Chihuahuas to retired Greyhounds.

4. Not just one, but two lives will be saved.

Talk about a win-win. Every mixed who’s rescued from a shelter not only gets a home, but also makes room for the next rescue dog to be cared for in a shelter. When you choose to adopt a rescue pup, you’ll reduce the population at overcrowded city shelters and help to shift demand away from harmful puppy mills. Every dog deserves a second chance at a permanent home — and with more than three million dogs entering animal shelters every single year, you’ve got literally millions of new besties to choose from.

5. Adoption won’t break the bank.

Purebreds can cost thousands of dollars to purchase from breeders, but shelter adoption fees tend to be between $100 to 500. (The adoption fee typically includes vaccinations, microchips, and spay/neuter surgeries too.) What’s more, shelters across the U.S. host “Clear the Shelters” days throughout the year — during these events, adoption fees are often waived entirely.

6. Mixed-breed dogs are cool looking.

Have you ever seen a Golden Retriever / Dachshund? What about a Corgi / Husky mix? The cross-bred nature of mutts makes all kinds of completely adorable (and let’s be honest, sometimes very funny) dogs possible. Plus, you get to throw around words like “Chiweenie” or “Morkie.”

7. It’s often easier to train a mixed-breed dog.

Mutts often have a more adaptable and flexible nature than purebred dogs, who have often been bred to perfect specific tasks (such as hunting). A mutt is less likely to go to extremes with specific behavioral qualities, such as digging or nosing, which is good news for pet parents. Whether you’re looking for basic cues (“shake”) or more advanced tricks, you may just have an easier time getting them there. Mixed breeds are even being trained as service dogs and police dogs, proving they’re just as capable as their purebred counterparts. 

8. Mixed-breed dogs are super loyal.

All dogs are faithful friends, but mutts are next-level loyal. Adopting a dog from a shelter helps form an unbreakable bond between pet and pet parent. We can’t 100 percent confirm this, but rescue dogs just seem to know they were rescued — and they show their gratitude by never wanting to leave your side.

9. Mutts are truly one of a kind.

The best part about mutts? They’re totally and completely unique, from their physical traits to their personality quirks. The varied lineage of mixed breeds guarantees that no two dogs are exactly alike, and that’s exactly why we love them.
