As I noted in an earlier post, there are approximately 75 million dogs in the U.S.
Every year about 7 million new dogs are acquired in the U.S. to replace those that die from disease, old age or accident.
Of these 7 million new dogs, approximately 53 percent are crossbreeds or mongrels, and approximately 47 percent are "pure breeds".
|More than half of all U.S. dogs are mixed breeds.|
To put a number on it, that works out to be approximately 3,710,000 dogs of mixed ancestry, and approximately 3,290,000 dogs that are pure breeds.
In 2014, to pick a year, the American Kennel Club registered less that 500,000 pure bred dogs (the number may be less than 400,000).
To put it another way, AKC registrations represented about 15 percent of pure bred dogs and about 7 percent of all dogs acquired that year. Since 2006, the AKC has not, so far as I can tell, published counts by breed.
|About a quarter of pure breed dogs are AKC-registered|
Assuming the same canine distribution as was evident in 2006 when breed count data was last reported, of the less than 500,000 pure bred dogs registered by the AKC in 2014, the top 10 breeds (out of 184 breeds total in 2015) will represent a little over half of all dogs registered, while the bottom 50 breeds will represent less than 1.5 percent of all dogs registered.
|More than half of all AKC dogs are in the top 10 breeds.|
The bottom 50 breeds sum to 1.2 percent of AKC-registered dogs.
