MCOA Breeder Referral Program

Purchase from Reputable Mastiff Breeders

The best way to get a healthy, happy, quality Mastiff puppy is to purchase one directly from a reputable breeder. Reputable breeders put the welfare of their dogs and the improvement of the breed above their desire for financial gain. Reputable breeders will take back or replace a puppy who is found to have a congenital defect. 

The Mastiff Club of America offers its members an opportunity to be listed on the clubs Breeder Referral program for a monetary donation to the club. These members are members in good standing with the MCOA and whom adhere to the clubs Code of Ethics.  Though it is the recommendation of the club for all Mastiff breeders to health screen their Mastiffs, the club does not have the ability to mandate each of its members. So it is the advise of the club to all potential buyers to screen your breeder before purchasing a puppy.

Questions to ask Breeders

The following are offered as possible questions you should ask the breeder of a Mastiff puppy you are considering acquiring. The FAQ ‘Getting a Dog’ contains additional, more general questions you may also wish to ask. 

  • Do they health test?

    Are the parents proven to be clear of the genetic problems discussed in Mastiff Health and Mastiff Health Awards? Have the suggested tests been performed on the parents? What is the breadth of the testing - just the parents? older siblings? grandparents? aunts & uncles? The breeder should be willing and able to produce copies of all test results, at least for the parents - if not offered - ask for them! Health testing completed through the American Orthopedic Foundation for Animals can be looked up on their database by searching the listed parents full AKC registered names. Visit for more information.

  • Why not?

    If the breeder doesn't test, ask why. Do NOT accept the answer that they don't test because they've never had a problem with something - how can they know they don't have a problem if they don't test? Do not accept their vet's opinion on hip dysplasia x-rays - a regular vet is not a trained radiologist - OFA uses three board certified radiologists to examine all x-rays.

  • How old is the Dam?

    How many times has she been bred? How far apart were the breedings? A Mastiff bitch should not be bred before 22 months of age nor after her 7th birthday; nor should her breedings, other than in exceptional cases, be closer together than 12 months.

  • What was the purpose of this breeding?

    Why did they choose the stud dog they used? What traits were they looking for? What improvements were they after? Are the breeders planning on keeping a puppy from this litter? If not, why not? If yes, how did they pick which one? A reputable Mastiff breeder will have a good reason for every breeding, either to improve their line or solidify and continue traits they already have. A reputable breeder will NOT be breeding just to have puppies to sell.

  • What faults do the dam and sire have?

    EVERY Mastiff has some faults. How has this breeding served to correct these faults? What are their good points?

  • What breed clubs do the breeders belong to?

    At a minimum, they should belong to the MCOA and/or one of regional Mastiff clubs, thus exhibiting an interest in supporting the future and direction of the breed, as well as being willing to place themselves under the oversight of their peers through the mechanism of the club's Code of Ethics.

  • Have the dam and sire been shown?

    Conformation showing is intended to identify the dogs that best fit the Mastiff standard; if the dogs haven't been shown, how do the breeders know, objectively, how well they are doing?

  • What are the living conditions of the breeder's dogs?

    Do they have adequate living space and room to exercise? Are the quarters clean and well kept? Is fresh water available?

  • What steps have the breeders taken to socialize the pups?

    Are they used to children? Other dogs? Other animals? Public places with lots of people? Early socialization is extremely important for a Mastiff; the lack of adequate socialization can cause serious problems later on.

  • What are the pups being fed?

    Are they being given supplements? If so, why? Mastiff pups will eventually grow to their genetically programmed size, it is much better for their health if they do so slowly. Good, quality food is usually all they need.

  • What are the terms of their contract?

    What guarantees do they offer? What conditions do they impose on your treatment and care of the dog? What penalties are imposed if you violate the terms of the contract? See section 4 of the MCOA Code of Ethics for a list of the minimum terms an MCOA breeder must include in their contract as well as other material they are required to supply to a puppy buyer.
