Survey of Shelter Dog Composition: Mutts vs. Purebreds
Shelter Purebred Data:

All of the shelters in this study maintain a website showing their current inventory of adoptable dogs. This survey provides 52 successive weeks of screen shots from each of these shelters showing the dogs they had on hand each week. It is our hope that by providing the actual screen shots of these published inventories, readers will gain a better understanding of the typical composition of shelter dog populations. To their credit, some of these shelters also disclose other pertinent information about their operations. It is especially helpful to know how many dogs each shelter takes in each year and whether those animals come from the local community or from distant locations. Several states recognize the public health, animal welfare and marketplace impact of shelters and rescues, and require them to be licensed by the state department of agriculture and report information about the number and types of animals they receive each year, and about the final disposition of those dogs. The NAIA Shelter Project records this information when it is available. At this point in time, the most comprehensive shelter information is published by Colorado’s Department of Agriculture.


Shelters Reporting the Highest Percent of Purebred Dogs
Shelters: 5
Period: 52 weeks

NOTE: The shelters with the highest number of purebreds all maintain dog relocation programs, which bring in dogs from outside their local service areas for adoption, many from distant states and Puerto Rico. Although Capital Area Humane Society in Ohio takes in dogs from outside its local service area, it does not fit the same profile as the other shelters listed above. The largest number of their purebreds are dogs described as Pit Bulls taken in from other shelters in Ohio.
