Triple T Mastiffs






Welcome to the home page of Triple T Mastiffs.  My name is Anna May and I’ve been in love with Mastiffs (also known as Old English Mastiffs) for the past 25 years and have owned and been actively involved with the breed for the last 11 years.  I have gone to numerous Mastiff National Specialties, Regional Specialties and Supported shows studying the breed and learning all that I can about them.  I have mentors and friends that include the top Mastiff Breeders in the Nation and probably the World as well as in my opinion the most knowledgeable people on health issues in our breed. 

I am an active member of the Mastiff Club of America (MCOA) and the Pacific Southwest Mastiff Club (PSMC).  My involvement and participation includes volunteering as the MCOA's Health Committee Co-Chair and I’m on the Board of Directors of the PSMC.  I serve as liaisons and have an active, strong, working relationship with numerous Genetic Researchers & Scientists, the American Kennel Club Canine Health Foundation (AKC CHF), the Orthopedic Foundation for Animals (OFA), and the Canine Eye Registration Foundation (CERF).  I am very passionate about Mastiff health!

 Health testing assists Mastiff breeders by letting them know what health issues their Mastiffs, their relatives, and their offspring have which can then be used as a tool when making breeding decisions.   There are currently two DNA tests available to Mastiffs through OptiGen®, LLC that identify eye problems in our breed.  One is for Progressive Retinal Atrophy (PRA) and the other is Canine Multi-focal Retinopathy (CMR1).  There are also several health tests available to identify dogs that have physical evidence (phenotype) of genetic health problems that the owner my not be aware of, such as hip dysplasia, elbow dysplasia, cystinuria, cardiac disease, thyroid disease and various vision problems.  It is my goal to have more DNA tests available to Mastiffs and I’m actively committed to this.

 I have a strong belief that a Mastiff should only be bred to improve the breed.  Each Mastiff should only be considered in a breeding program if it is a good representative of the Mastiff breed (exhibits Type), that it is healthy (proven through formal Testing) and that it has a sound Temperament.  I also believe that it is important to wait until they have matured enough to see what they will ultimately develop into before making breeding decisions.

 My Mastiffs are family members and their health and quality of life are a top priority for me.

 Feel free to contact me with questions or to just “Talk Mastiffs”. 

Thank you for health testing your Mastiffs & for participating in health research projects!
