The Mastiff Club of America’s DNA Sub-Committee promotes the use of DNA to insure the integrity of our Mastiff pedigrees and to further the health of our Mastiffs. We encourage Mastiff breeders and owners to AKC DNA Profile all of their Mastiffs and to donate their blood for DNA banking which can be used for health research studies offered now and in the future.

Repository: Mastiffs can bank DNA to help with future health research studies and future
DNA testing.  We can donate our Mastiff’s DNA to the CHIC DNA Repository to be used in research

Althought OptiGen Long-Term DNA Storage is no longer accepting samples those that have blood stored can continue to use stored blood for future health research studies and/or for future DNA tests as they become available to Mastiffs.  We encourage everyone participating in the CHIC DNA Repository to include your dog’s AKC DNA Profile number on the submission form!  

DNA Statistics:
AKC DNA Profiling: There were Mastiffs submitted for voluntary AKC DNA Profiles in 2009; to date
a total of 4487 AKC DNA Profiles on Mastiffs have been submitted. .CHIC DNA Repository: As of
June 25, 2019, 284 mastiffs blood samples were submitted and donated to the CHIC DNA

Canine Health Information Center (CHIC) News
Since many diseases are late onset, the bank recognizes that periodic updates to the health records
of each dog are important. Owners will be contacted approximately every two years to determine if
there are any health updates. However, owners are encouraged to proactively contact the CHIC
DNA Bank to update the health status of their dog(s) whenever there are significant changes.
They are primarily looking for new disease diagnosis, as an example, a dog that had developed
cancer, Cardiac Disease, or been diagnosed with hip dysplasia would all be updates that should be
incorporated into the dog’s record.  They are also interested in the date of death and the reason of
death when our dogs pass away. CHIC DNA Repository e-mails should be sent to:
The MCOA DNA Sub-Committee’s on going goal is to encourage more participation in CHIC DNA
Repository and AKC DNA Profiling by educating Mastiff owners to understand the enormous
potential of the future of DNA research in greatly reducing and hopefully eliminating some of the
health problems and diseases that plague our breed.  We want this to be our legacy to future
generations of Mastiffs.
