10 Fantastic Flat-Coated Retriever Mixes
With their cheerful dispositions, enduring puppy-like energy, and adventurous nature, the Flat-Coated Retriever makes a wonderful family companion. Flat Coats are a rare breed in the U.S., but that being said, Flat-Coated Retrievers and mixes can be found in some shelters and rescues across the country.
Flat-Coated Retriever Mixes
A Flat-Coated Retriever mix’s looks depend on the traits they inherit from each of their parent breeds. Some pups will take on the build and coat type of their Flat Coat parent, while others may take after their other parent—or appear as a balanced blend of the two. That’s part of the fun of mixed-breed pups: they’re wonderfully diverse and unique in appearance.
Another advantage of mixed breeds is their generally lower risk of genetic conditions commonly seen in purebreds. According to a study that included more than 100,000 dogs, purebreds were nearly three times more likely to develop recessive genetic diseases than mixed-breed dogs.
Below are some delightful Flat-Coated Retriever mixes you may encounter through FurPetVo partner rescues and shelters—each waiting for their forever home.
Border Flat Retriever: Flat-Coated Retriever + Border Collie
Combining two energetic and intelligent breeds, the Border Flat Retriever is highly active and loves problem-solving games. With parents from both the herding and sporting groups, these enthusiastic pups thrive in homes offering plenty of mental enrichment, daily exercise, and rewarding training.
Flat Lab: Flat-Coated Retriever + Labrador Retriever
The Flat Lab blends two exceptionally friendly breeds—making them an ideal choice for families with children or anyone seeking a loyal, sociable canine companion. Both parent breeds retain playful, puppylike energy and a touch of mischievousness well into adulthood, so this mix does best with pet parents who cherish those spirited qualities.
Golden Flat Retriever: Flat-Coated Retriever + Golden Retriever
The Golden Flat Retriever inherits a long, water-resistant, feathered coat from both parents. Their coat may be flat-lying and smooth or wavy and dense, with colors ranging from golden and light golden to golden-red, liver brown, or black. Highly social and outgoing, this mix typically loves water and retrieving—and often excels at both.
Floodle: Flat-Coated Retriever + Poodle
The Floodle combines the intelligence and agility of the Poodle with the affectionate, exuberant energy of the Flat-Coated Retriever. They may sport a low-shedding, curly coat if they lean toward their Poodle parent—but both breeds contribute water-resistant coat traits. Floodles typically love swimming and flourish in active, engaged households.
Aussie Flat: Flat-Coated Retriever + Australian Shepherd
The Aussie Flat often inherits high energy from both parents and thrives with consistent mental stimulation, interactive games, and outdoor adventures. They may display natural instincts for herding, retrieving—or both. Coat length ranges from medium to long, with colors and patterns including merle, black-and-tan, and red-tri.
German Flat-Coat: German Shepherd + Flat-Coated Retriever
This agile mix brings together the alertness, loyalty, and protective instincts of the German Shepherd with the Flat Coat’s cheerful, affectionate temperament—ideal for families seeking a confident yet loving companion.
Flat Newfie: Newfoundland + Flat-Coated Retriever
Since Newfoundlands are part of the Flat-Coated Retriever’s ancestry, this mix often resembles a larger, stockier version of the Flat Coat. Expect a gentle, affectionate, and water-loving dog with strong swimming ability and calm confidence.
Flat Basset: Basset Hound + Flat-Coated Retriever
This charming cross may feature the Basset’s signature out-turned paws, low-slung build, and long, silky coat. While often sweet-natured, Flat Bassets can be vocal and strongly scent-driven—so secure fencing and leash walks are essential.
Chatham Hill Retriever: Cocker Spaniel + Flat-Coated Retriever
This popular medium-sized mix blends the merry, affectionate nature of the American Cocker Spaniel with the retrieving drive and steady energy of the Flat Coat. Lively but not overly rambunctious, Chatham Hill Retrievers make excellent companions for active families and first-time dog owners alike.
Flatsky: Husky + Flat-Coated Retriever
This large, spirited mix often displays the Husky’s playful independence and alert curiosity alongside the Flat Coat’s friendliness and stamina. High-energy and free-spirited, Flatskys need consistent engagement, structured routines, and plenty of outdoor time.
Things to Know About Flat-Coated Retriever Mixes
Flat-Coated Retriever mixed-breed pups can differ significantly in appearance, size, and temperament due to their genetically diverse backgrounds. Still, many will reflect core traits inherited from their Flat-Coated Retriever parent—including enthusiasm, intelligence, and a strong desire to connect with people.
They Tend to Be Big Dogs
Flat-Coated Retrievers are large dogs—typically weighing 60 to 80 pounds at maturity—and most common crossbreeds (like Labs, Goldens, and Newfoundlands) are also large. As a result, most Flat-Coated Retriever mixes weigh at least 50 pounds as adults. If you're uncertain about your pup’s eventual size, consult your veterinarian for developmental guidance—and ensure you’re ready to meet the needs of a big, active dog.
Some May Carry Increased Cancer Risk
Purebred Flat-Coated Retrievers face a heightened risk of certain cancers—particularly histiocytic sarcoma, an aggressive form of cancer. In one 10-year study of 174 Flat Coats, 42% died from cancer, and nearly half of those cases involved histiocytic sarcoma.
This predisposition can be passed to mixed-breed puppies, though the risk may be reduced when crossed with breeds less prone to cancer. However, mixes like the Golden Flat Retriever may still carry elevated risk—since both parent breeds have higher-than-average cancer rates.
They Love to Run—and Need Daily Exercise
Like most sporting dogs, Flat-Coated Retriever mixes thrive on movement. Often considered the most energetic of all retriever types, they typically enjoy running, fetching, swimming, hiking, and vigorous play. Unless crossed with a notably low-energy breed, they’ll likely inherit the Flat Coat’s “Energizer bunny” stamina and zest for life. Professional training support can help channel that energy constructively.
Many Have Floppy Ears—but Not All
Purebred Flat-Coated Retrievers have long, silky, wavy, feathered ears that hang close to the cheeks. Many mixes inherit this trait—but it’s not guaranteed. Crosses with erect-eared breeds (like German Shepherds, Border Collies, or Australian Shepherds) may result in semi-erect or fully upright ears. If your pup does have floppy ears, regular cleaning and drying after swimming or bathing helps prevent infections.
