If you’re picturing a dog that looks like a miniature Scooby-Doo or perhaps a giant hound with floppy ears that drag on the floor, you aren't actually that far off. The Great Dane Beagle mix—often affectionately (and sometimes confusingly) called the "Great Beagle"—is one of those designer crosses that makes people stop in their tracks at the dog park. It’s an odd pairing. You’ve got the Beagle, a scent-obsessed hunter that rarely tops 30 pounds, and the Great Dane, a literal titan of the canine world that can easily clear 150.
But here's the thing: biology is weird.
When you mix these two, you don't get a "medium" dog. Well, sometimes you do, but more often than not, you get a dog that possesses the stubborn, vocal heart of a hound trapped inside a body that might or might not fit in your sedan. Honestly, it's a roll of the dice every single time.
The Genetic Lottery of the Great Dane Beagle Mix
Breeding a Great Dane and a Beagle isn't exactly a standard procedure in the world of responsible animal husbandry. Because of the massive size disparity, this cross is almost always the result of a Great Dane mother and a Beagle father—usually via artificial insemination. You cannot have a Beagle mother carrying Great Dane puppies; it's physically impossible and dangerous for the dog.
What happens when those genes collide?
Usually, you get a dog that stands about 20 to 24 inches at the shoulder. They tend to have a deep chest, a long snout, and ears that are larger than a Beagle's but not quite as "velvety curtain" as a Dane's. Their coat is almost always short and dense.
Color-wise, you’re looking at a spectrum. You might see the classic tricolor pattern of a Beagle (black, white, and tan), or you might end up with the stunning mantle, brindle, or harlequin patterns seen in Great Danes. One thing is certain: they shed. A lot. It’s that short, stiff hair that weaves itself into your upholstery and stays there until the end of time.
Size Matters (And It's Hard to Predict)
Most owners find their Great Dane Beagle mix settles somewhere between 50 and 80 pounds. That’s a "large" dog, but compared to a 170-pound Dane, it feels manageable. However, I’ve seen outliers that barely hit 40 pounds and others that push 100. If you are living in a tiny apartment with a strict weight limit, this is a risky bet.

The growth rate is also something to watch. Danes grow fast—too fast sometimes—which can lead to joint issues. Beagles are prone to obesity. Put them together, and you have a dog that needs very careful nutritional management during their first 18 months to ensure their skeleton can keep up with their mass.
Personality: A Mix of "Go" and "No"
Beagles are driven by their noses. If they catch a scent, they are gone. They have high "prey drive," which is just a fancy way of saying they think squirrels are the enemy and must be pursued at all costs.
Great Danes? They’re "velcro dogs." They want to sit on your feet. They think they are lap dogs. They are generally low-energy compared to other giant breeds, preferring a solid nap to a five-mile hike.
When you get a Great Dane Beagle mix, you're basically getting a dog with a split personality.
One minute, they’re dead to the world on the sofa. The next, they’ve smelled a sandwich in the neighbor's kitchen and are howling at the door with the force of a foghorn. That "baying" sound is a hallmark of the Beagle side, and when it’s amplified by the massive lung capacity of a Great Dane, it is loud. It’s not a bark. It’s a rhythmic, soulful, "Awoooo" that will definitely annoy your neighbors.
You’ve got to be prepared for the stubbornness. Beagles are notoriously difficult to train because they’re easily distracted by, well, everything. Danes are sensitive and can be a bit timid. You can't use a heavy hand with this mix. They’ll just shut down or decide they don't like you. Positive reinforcement isn't just a suggestion here; it's the only way you're going to get them to sit.
Health Issues You Can't Ignore
Every breed has its "stuff." When you mix them, you hope for "hybrid vigor," which is the idea that crossing two breeds reduces the risk of genetic diseases. This is partially true, but you can also end up with the worst of both worlds.

The Bloat Factor
This is the big one. Great Danes are the #1 breed at risk for Gastric Dilatation-Volvulus (GDV), or "bloat." This is where the stomach fills with gas and twists. It’s a life-threatening emergency. Since the Great Dane Beagle mix usually inherits the deep-chested build of the Dane, they are at significantly higher risk than your average mutt.
Pro tip: Don't use elevated bowls unless your vet specifically tells you to. Recent studies, including those from Purdue University, suggest that raised feeders might actually increase the risk of bloat in some dogs. Stick to the floor and feed multiple small meals a day.
Hip Dysplasia and Cherry Eye
The Dane side brings the risk of hip and elbow dysplasia. The Beagle side brings a propensity for "cherry eye" (a prolapsed third eyelid) and hypothyroidism.
Expect to spend a decent amount of money on preventative care. You’ll want a high-quality joint supplement like Glucosamine and Chondroitin started early. Also, Beagles have those long, floppy ears that trap moisture. If you don't clean your Great Dane Beagle mix's ears at least once a week, you’re basically inviting a yeast infection to move in.
Living with the "Great Beagle"
Let's talk about your house.
If you have a Great Dane Beagle mix, your coffee table is no longer safe. This dog is at the perfect height to clear a surface with one wag of a tail. They are also notorious "counter surfers." The Beagle brain says, "Find food," and the Great Dane body says, "I can reach that roast chicken on the back of the stove."
They need space, but surprisingly, they don't need a massive yard if you’re diligent about walks. A 45-minute brisk walk in the morning and some nose-work games in the afternoon usually keep them satisfied. If you don't give them a job for their brain, they will find one. Usually, that job involves deconstructing your throw pillows to see what’s inside.

Exercise Needs
They aren't marathon runners. Don't take this dog on a 10-mile jog. Their joints can't handle it, especially if they lean more toward the Great Dane side of the size spectrum. Instead, think about "sniffari" walks. Let them lead. Let them sniff every blade of grass. It wears them out mentally more than a fast run ever would.
Why This Mix Isn't for Everyone
Honestly, the Great Dane Beagle mix is a polarizing dog.
If you want a highly obedient dog that will win agility competitions, look elsewhere. This dog is going to look at your command, weigh its options, and decide if the treat you’re holding is worth the effort of moving its 70-pound frame.
However, if you want a companion that is fiercely loyal, incredibly goofy, and generally sweet-tempered with children, this could be the one. They have a certain "human-like" quality to their expressions. They look at you with those big, soulful hound eyes and you just melt.
A Quick Word on Rescues
Before you go looking for a breeder (and honestly, finding a "reputable" breeder of this specific designer mix is tough), check your local shelters. Because they are a large, vocal mix, they often end up in rescues when people realize they can't handle the size or the noise. Organizations like the Great Dane Rescue or Beagle-specific rescues often have mixes.
Actionable Steps for New Owners
If you’ve already fallen in love with a Great Dane Beagle mix, or you’re about to bring one home, here is your "Day One" checklist to keep things from going off the rails:
- Invest in a "Slow Feeder" bowl. This is your best defense against bloat. It forces them to eat one kibble at a time rather than inhaling their food like a vacuum.
- Get the "Hush" command down early. You won't stop the baying entirely—it’s in their DNA—but you can teach them when to stop. Use high-value treats (think freeze-dried liver) to reward silence.
- Proof your counters. Seriously. Move the toaster, move the fruit bowl, and definitely move the mail. If it’s at nose level, it’s theirs.
- Find a vet who knows Giant Breeds. Not all vets are comfortable managing the specific needs of dogs with Great Dane blood. You need someone who understands the nuances of anesthesia and growth rates for large-frame animals.
- Socialize, socialize, socialize. Because the Dane side can be fearful and the Beagle side can be stubborn, you need to expose them to every sound, smell, and person possible before they hit the six-month mark.
The Great Dane Beagle mix is a weird, wonderful, loud, and loving contradiction. It’s a dog for someone who doesn't mind a bit of chaos and has a very good vacuum cleaner. If you can handle the "Awooo" at 2:00 AM because a stray cat walked by, you’ll have a best friend for life.
