Presentations and Publications

Highlights:

A new study finds very young dogs with little human contact can understand pointing gestures—and that the ability has a strong genetic basis.

The AKC Canine Health Foundation (CHF) and its donors have invested in ground-breaking research to explore the cognitive abilities of our canine companions – particularly those that work closely with us as detection dogs, service dogs, assistance dogs, and more.

Dogs are born ready to communicate with humans, according to a new study involving hundreds of 8-week old puppies.

Presentations:

Our research team and collaborators share their expertise in canine research for our community and the public in various presentations. These presentations allow us to show how our work can impact our programs and provide benefits and greater success not only for our dogs, but also for our clients and the disability community.

Canine Companions, along with its collaborators from various research programs, publish findings that highlight our understanding of canine health, behavior and the impact of dogs on the human animal bond. We are proud to be a leader in the service dog industry. By publishing results in peer-reviewed journals, our research benefits the dog community at large as well as other organizations working to help individuals with disabilities lead more independent lives. Here’s a list of publications that the Canine Companions research team and/or data has contributed to.
