Dear Devoted Dog Owner,

DDC Veterinary is excited about research being conducted on the Genetics of Canine Hyper-Sociability. The study is being performed by Dr. Bridgett M. vonHoldt, Department of Ecology & Evolutionary Biology, at Princeton University.

What is Canine Hyper-Sociability?

  • Genetic findings provide a possible story for how humans domesticated wolves into dogs, which is suggested to have been through “the survival of the friendliest."
  • The research group recently identified mutations in a handful of genes that influence how friendly a dog or wolf is towards humans.

For more information, visit the Canine Hyper-Sociability website.

Dr. vonHoldt is working to develop a successful genetic survey for these mutations from dogs' DNA samples. Her group needs samples from all types of dogs. If you choose to participate, Dr. vonHoldt will send you a short report describing the number and type of gene variants your dog carries. 

Want to join the study? Here's what you need to do:

  • Stage 1: Basic data collection Three forms: The consent form, demographic information and a short 42-question behavioral assessment of each individual dog. All forms can also be found on the project’s website.
  • Stage 2: Behavioral video data collection Two short behavioral tests you can conduct and record at home with your dog! Sociability test and Problem Solving test
  • Stage 3: Genetic sample donation Once all of the forms and video tests have been received by Dr. vonHoldt, she will send qualified participants the non-invasive cheek swab kit that can be collected at home, without the need for a vet visit. (Whole blood samples also accepted.)

Scan completed forms and name the file as "LastName_FirstName.pdf" Email the forms to Dr. vonHoldt at Put "WBS Participation" in the subject of the email, otherwise the email maybe discarded. Or mail the forms to:
