You get an American Corgi by breeding a Pembroke Welsh Corgi and a Cardigan Welsh Corgi together, so you can guess that the appearance of these two dogs is similar. However, Pembroke Welsh corgis are only found in select coat colors including white, black, red, and tri color, while the American Corgi is frequently found in a merle coat.
The merle coat is genetically impossible for a Pembroke to come in, which is why the American Corgi exists in the first place. Many breeders want the merle coat often found on the Cardigan Welsh Corgi. However, they want this distinct pattern and coloring on a smaller breed of dog. Otherwise, American Corgis and Pembroke Welsh Corgis have elongated bodies and short legs. They also have erect ears and they may or may not have a tail.

There are distinct differences in the ancestry and breeding of American Corgis and Pembroke Welsh Corgis. For example, the Pembroke Welsh Corgi originated as far back as 1000 AD, bred in the Welsh countryside for farm work and herding. The American Corgi is a much more modern breed compared to the Pembroke Welsh Corgi. It was created by breeding a Pembroke Corgi with a Cardigan Welsh Corgi. The result was a Corgi with a merle coat.
The American Corgi is considered a designer dog, bred for specific physical features rather than health and wellness. Breeding designer dogs for this purpose often leads to controversy, given the fact that American Corgis are often born with genetic issues due to their merle coat coloring.

The behaviors of the American Corgi and the Pembroke Welsh Corgi are very similar to one another. However, Pembroke Welsh Corgis tend to have more energy than American corgis, given their healthier breeding and natural genetic process. Though, it always depends on the specific dog as well as the health and care that it is receiving.
American Corgis are friendly and a joy to have around, similar to Pembroke Welsh Corgis. However, many Pembroke Welsh Corgis exhibit more herding behavior compared to American Corgis. This is something to keep in mind if you have young children in the home.

A final difference between American Corgis and Pembroke Welsh Corgis is their lifespan. Despite American Corgis being billed as a genetically sturdy cross breed of dog, Pembroke Welsh Corgis live longer on average compared to American Corgis. This is likely due to the rampant genetic issues found when crossbreeding Pembroke Welsh Corgis and Cardigan Welsh Corgis.
For example, American corgis live an average of 10 to 12 years. Pembroke Welsh corgis live anywhere from 13 to 15 years, depending on the health of the individual animal. This is why it is important to always do your research. You should only purchase a purebred or designer dog from a reputable breeder. Plus, there’s always your local animal shelter if you are looking for a lovable and loyal companion rather than choosing a designer dog!
