Which dog breeds are most common in America?

Ancient dogs are common in the United States, but only the most rare are actually native breeds, according to a new study.

That finding suggests a genetic bottleneck in the American dog breeds’ spread across the continent.

Researchers looked at the genetic diversity of the most commonly known dog breeds in the U.S. and found that the breeds with the most genetic diversity were found mostly in the Great Plains, the western parts of the Great Lakes, the northern regions of the Dakotas and the Southwest.

The study, published in the journal Current Biology, looked at a total of 5,943 breeds that have been collected over the last four decades.

It found that a whopping 85 percent of these breeds are either American breeds or closely related breeds, with the remaining 10 percent having varying degrees of variation in ancestry.

The findings suggest that the dogs that spread across America were a bit more genetically diverse than the dogs currently living there, the researchers said.

The researchers said their results suggest that while there may have been a genetic difference between native breeds and the American breeds, it was not a major difference that led to the spread of the breeds.

“A genetic bottleneck may have led to a decline in the number of domesticated breeds in general,” study lead author David A. Burchardt, an evolutionary biologist at the University of Minnesota, told the Associated Press.

It’s likely that this genetic bottleneck occurred around the time that the domestication of the horse, the ancestor of most dogs, began, the study said.

When a dog breeds, genetic differences can be inherited from one generation to the next, and then can be passed down through generations to the dogs they breed with, researchers said, adding that these dogs may be more closely related to the domestic dog, such as the Staffordshire bull terrier, than they are to the European breeds that are used for breeding.

According to the study, there are about 1,200 breeds that make up the United State’s dog population, with about 1 percent of breeds living in every U..

S., and about 10 percent of dogs that live in every state.

Among the breeds, the most common is the Stafford and Chowan terriers, which make up about 20 percent of the U-dog population.

Other popular breeds include the Labrador retriever, Boston terrier and Labrador mix, the authors said.

In contrast, there were only about 30 American breeds in every population, the largest percentage being the American bulldog, the breed that is the ancestor to the American Pit Bull Terrier.

There is also a high degree of variation within the breeds’ breeds, and some breeds may be a mix of other breeds, such the Stafford Bull Terriers, the American Staffordshire terrier or the American boxer mix, according the study.

Some breeds that live together, such American Stafford, American Pit bull, American bull terriers and bulldogs, have genetic differences that allow them to be more easily crossbred, while other breeds may not be genetically distinct enough to be distinguished by genetic testing.
