There are two recognized/established breeds of Corgi:
The Pembroke Welsh Corgi
and
The Cardigan Welsh Corgi.
An “American Corgi”, however, is not a breed of corgi
“American Corgis” are actually a mixed breed: a cross between a Pembroke Welsh Corgi and a Cardigan Welsh Corgi.
These two breeds are typically cross-bred by irresponsible (backyard) breeders in an attempt to produce merle-colored dogs with the smaller body and personality of a Pembroke.
This desired look is often referred to as a “Merle Pembroke”.
Despite being bred for a “Merle Pembroke” appearance, “American Corgis” can come in a variety of shapes, sizes, colors, and can either have the temperament and personality of a Pembroke, a Cardigan, or a combination of the two.
These kinds of dogs that are mixed primarily for appearance are commonly referred to as “designer breeds” or “designer mutts”.
The intentional breeding of “American Corgis” is considered highly unethical.
Breeders that produce “American Corgis” typically prey on unsuspecting and uninformed puppy buyers by charging obscene prices for cross-bred puppies which they market as “purebred corgis with rare coloring”.
In reality, crossing Pembrokes and Cardigans can produce unpredictable puppies, many of which suffer from long-term behavioral and/or health problems
Pembroke Welsh Corgi vs. Cardigan Welsh Corgi
There is a common misconception that Pembroke Welsh Corgis and Cardigan Welsh Corgis are the same breed… however, they are not.
They each have their own unique histories and lineage.
The Pembroke Welsh Corgi is thought to descend from members of the Spitz family, brought to Wales when Flemish weavers settled in the Welsh county of Pembrokeshire in the 12th century.
The Cardigan Welsh Corgi was developed separately in Cardiganshire and descends from the Teckel (hound) family.
Pembrokes and Cardigans are fundamentally two separate and unique breeds that are historically, structurally, and behaviorally very different from each other.
Appearance
The most obvious difference in appearance between the two breeds is their tail.
Cardigans have long, foxlike tails whereas Pembrokes typically have their tails docked close to their bodies.
Pembrokes are the smaller of the two, weighing in at roughly 20-30 lbs. Their coats only come in red, sable, fawn, red-headed tricolor, and black-headed tricolor.
Cardigans are usually a bit heavier. They typically weigh anywhere between 25-40 lbs. Their coats come in a variety of colors: brindle, black and white with brindle or tan points, red and sable with white markings, and blue merle.
Personality
When it comes to personalities and temperament, Pembrokes are a high-energy, sometimes overly friendly, outgoing breed.
Cardigans, on the other hand, are a bit more laid back.
They generally have less energy than Pembrokes and can be more reserved in new situations.
Are American Corgis a Breed?
No. American Corgis are not considered an established breed, nor are they recognized by the American Kennel Club (or any other legitimate dog registry).
There have been attempts to create a recognized “American Corgi Club”, however, with a lack of support from both the Cardigan Welsh Corgi Club and the Pembroke Welsh Corgi Club, it’s unlikely that American Corgis will ever become a recognized breed.
The lack of support from both clubs is largely attributed to the fact that American Corgi breeders have failed to identify exactly what fault they are trying to improve by mixing the two breeds.
When asked about the purpose of this cross-breed, The American Corgi Club Facebook page stated:
“We are still working on it but some of the differences will involve length of back and leg. We hope to produce a more athletic dog, and frankly a healthier one with out the disc problems a very long back is prone to.”
Breed experts question the logic in crossing two breeds predisposed to back problems in an attempt to create a “healthier dog with a healthier back”.
This has only furthered suspicions that “American Corgis” are unethically produced and are solely being bred for their appearance.
The Dangers Associated With Breeding American Corgis
You will often hear American Corgi Breeders use gimmicky terminology like “hybrid vigor” to support their claims that they are producing “healthier dogs”.
This couldn’t be further from the truth.
Structure
Although both Pembrokes and Cardigans are dwarf breeds, the structural differences between them are significant.
Reputable breeders of Pembrokes and Cardigan will show their dogs in the conformation ring to prove their breeding dogs are structurally sound to reproduce.
Since mixed breed dogs cannot be shown in a conformation ring, American Corgi Breeders would need to prove the conformational (structural) integrity of their breeding dogs in some other way, such as sport/working titles.
However, most American Corgi breeders do not prove the structural soundness of their dogs in any capacity.
This can lead to the breeding of dogs that are not structurally sound and, as a result, the puppies they produce are highly predisposed to physical injury.
Hereditary Diseases
Despite striving to produce a “healthier” dog, American Corgi breeders typically fail to perform the basic preventative health tests required by both the PWCCA and the CWCCA.
These tests/health clearances include all of, but are not limited to:
Pembroke Welsh Corgi
- Von Wilbrand Disease (vWD)
- OFA or PennHIP
- CAER/CERF Eyes
- DM
Cardigan Welsh Corgi:
- PRA
- OFA or PennHIP
- CAER/CERF Eyes
- DM
These tests are crucial to ensuring hereditary and preventable diseases are not being passed on to future offspring.
Testing is even more important when we are considering mixed breed dogs like American Corgis.
American Corgis are susceptible to diseases that are present in both Pembrokes and Cardigans.
This means that a disease found only in Pembrokes or only in Cardigans can both be present in American Corgis.
The Risks of Double Merle
Irresponsible and uneducated breeders that intentionally breed for a merle coat color can unknowingly produce “double merle” puppies.
A double merle is a puppy that receives the merle gene from both parents.
This causes the dog to be blind, deaf, or both.
Hundreds of double merle corgis are produced every year by backyard breeders producing “American Corgis”.
Due to their birth defects, many of these dogs end up in rescues, but most are euthanized by their breeders.
Until American Corgi Breeders make drastic changes in their breeding practices, reevaluate the dogs they are breeding, and start implementing thorough health clearances and testing, they will continue to be referred to as unethical, irresponsible, and backyard breeders.
Are Merle Corgis Purebred?
Pembroke Welsh Corgis come in a variety of colors: red, black & white, sable, fawn — however, a purebred Pembroke Welsh Corgi cannot be merle.
If a breeder is marketing a merle dog as a PWC, then that dog is likely mixed with another breed that carries the merle coat gene and is not a purebred PWC.
Cardigan Welsh Corgis, on the other hand, are able to naturally carry a merle coat gene and therefore merle Cardigans can be purebred.
Were Pembrokes ever merle?
No.
One of the arguments that is frequently used to justify merle Pembrokes is that centuries ago, when Cardigans and Pembrokes were bred together, Pembrokes carried the ‘blue gene’.
However, they fail to mention in Pembrokes, “blue” does not mean blue merle.
In Pembrokes, ‘blue” is a slang term to describe dogs with dilute coats.
These diluted dogs have a distinct smokey cast over their coats and their nose/eyelids will also be slate grey/blue or liver-colored depending on their coat color. (hence the term “bluey/bluie”)
A dilute coat can be inherited by any dog independent of coat color, it simply needs to inherit two copies of the dilute gene (one from each parent)
When it comes to a blue merle coat color, Pembrokes are genetically incapable of carrying the merle coat gene.
In other words, that means if a corgi is merle colored, it cannot be a purebred Pembroke. It’s physically impossible.
Alternative Breeds to “American Corgis”
If you are interested in the characteristics of an “American Corgi”, then you are likely interested in a small to mid-sized herding breed dog.
There are many purebred dogs, produced by ethical preservation breeders, that would be a great alternative for you and your family to consider.
Responsibly Bred Alternatives to American Corgis:
- Cardigan Welsh Corgi
- Pembroke Welsh Corgi
- Swedish Vallhund
- American Shepherd
- Australian Shepherd
- Border Collie
- Collie
- Shetland Sheep Dog
- Australian Cattle Dog
Final Thoughts
These dogs are the result of dangerous breeding practices.
Due to the inherent risk of mixing two different dogs, the practice of breeding American Corgis has to be done responsibly and carefully.
Unfortunately, a majority of American Corgi breeders do not prove their dogs, and even more fail to accomplish the minimum health tests as required by Cardigan and Pembroke parent clubs.
The production of unhealthy and untested dogs that are susceptible to all of the risks and diseases found in BOTH Pembrokes and Cardigans, in the hope of creating a “new breed” with a merle coat color.
The AKC currently recognizes 197 unique breeds.
There is certainly one that already exists that fits your family’s needs.
Do not support irresponsible American Corgi breeders, do your due diligence, and find a dog breed that is ethically bred and right for you or your family!
Sour on Designer dogs. Used to be an E-list puller and rehab for 3 years when the doodle craze started every design that is W A I , there is rest of litter of mutts that end up discarded if not destroyed when faults appear early. Last decade exploded specially corgi, dash and chi mixes added to the doodle flood. And I currently have 4 defect medicine chest puppies.
short epic: Careful breeder of working cardigans has bitch watched by BYB family member . We were waiting 2 years for pup (her adult retirees were not warm to my son) of her final breeding that was botched by accidental breeding by designer nightmare (later revealed male owner breeding for merle, teacup and tailess auggi).
When she decided to stay firm on retiring her bitch and was leaving country to compete in trials for her current show dog. So we went to get our deposit back . My son liked one of the rejects and this 5 month old lil mutt she really velcroed to him. Because she was marked as potential service dog, she was going to have health check for soundness (at cost of 50 kept out of deposit)since she is a cryptic out of 2 merles then we could pick her up. She was waiting at the 100 mile closer relatives and was bred by her white with cream pink eye brother that was kept!
Original Cardigan is papered large sport dog with ch lineage but disqualified for being red merle*cryptic and long hair, she also was masked sable&white…I was after fluffy with coloration like our former service dog bur economy size.
The Designer* Teacup Toy Au/gi is tri merle patched natural tailess (patched aka overwhite).. aka frightening mess.
So… 6 puppies that are from a double merle & merle with inbred lineage(for tailess)
1 white with merle ear, 1 overwhite, all cryptic merle. 3 sable and clear sable.
Double coats but mealy and they All went bald including the LH pup &mom for 2 months. Steroids and allergy meds now see coat return which changed texture, hid the merle and sable in all but white pup ears and the rehomed red sables tail and onset heavy grizzle ticking in all.
Two tailess (the rumpy had problems out of box), 2 tail defects bad enough to REQUIRE dock at bad points, two gorgeous foxtails.
Last two stillborn and rescued. 4 have jaw defects. The white has a 2 inch overbite that will require tooth extraction and has a pupil defect in one blind eye, 4 have mild underbite, one was a cripple (rumpy)until therapy and supplements corrected.
The female midget overwhite has suspected heart problem with her extreme miniaturization. From a teacup auggie of 11 lb and a 40lb cardigan originals.. she is 4 lbs smaller than litter and estimate adult 5 lbs. Vet also estimates short life.
The biggest is 5 lb at 13 weeks. The teacup was achieved. Did not want. Nor did I give them to sire owner when she offered. >: c Specially she wants the lil girl.
I could go on. I worked and bred dogs few decades ago. I never saw so many weird coat changes and defects in a single litter!
I never dealt with merles nor bred for something so hard as tailess. I was carefully paranoid about linebreeding.
That same person (I so wanna say her name) is going to be ‘working’ on “teacup corgis”. And “rare White & Merle Pembrokes”…… in Glendale AZ. I’d steer clear of any designer “x-gis and unpapered “rare” purebreds from the region.
Meanwhile, I rehomed the 2 healthy pups and am stuck with 4 that will be vet speeddial dogs. If I had just sent them off on appearance, they would all be e-list pound puppies by now. I sterilized the whole lot of course.
This horror story is a warning from buying “rare” or “cheap” or designer.
At best if you get a fee mutt as pet or working animal, remember to have it fixed! I am not against a new breed, but there are plenty older, working or recognized breeds .. anything that requires constant outbreeding to keep type but cant maintain a standard after f2.. is just a MIX
>:c
On a positive note? despite looking like JRT mix puppies, herding and stalking and eye are hardwired into mom and 5 of the 6 puppies. The temperament also follows the Cardigan I liked. I finally stopped mom from trying to gather us with bullying (dragging at, nipping at & pushing)
They are quick learners, obedient and very athletic. After being teen mom and rejecting litter, the original pup has not changed her demeanor with my son and follows his hand signals and stays close. They are pretty quiet though bark is sharp like a collie. The females are noisiest and nosiest. NONE like interlopers near the fence be it bird, cat or human. Have to break the mom of strangerdanger, she has to pass CGC for free advanced training.
I used to raise and show Cockers. That was back in the day when they were nice dogs. When folks started “mixing” the, albeit, Cockapoos, etc, I decided I didn’t want to be a part of that and got out of the business.
I read this whole article and I thank you for not being a part of the “mixing” thing. It has really gotten out of hand.
I was totally unaware of this when I purchased my American corgi. I love this dog very much, but I’m glad I had her spayed. I paid $1,000 for her only to find out now that breeding them is unethical. Why do people do crap like this when it is the dog that pays the highest price?
They do it because uneducated buyers will pay $1000 for a mutt. Corgis top out at $500 in my area. We used to breed Aussies but have retired our dogs.
People are the worst.
I’ve got a rescue that has an odd coat coloration. I suspected that she was either a Pembroke and Cardigan mix or a Pembroke and Australian Cattle Dog mix. Now I know. Fortunately she is healthy and very sweet. Her original owners were just as irresponsible as her breeders.
We purchased an American Corgi because we were uneducated. We got lucky ours is a healthy male that we immediately had him neutered. We were lucky.
I read amazing information about this breed in your article which I don’t know before. I have this breed also and I need your expert suggestion regarding its eye issues. My hybrid corgi is often prone to eye issues, and which medication is perfect for this?
