Health-tested Mastiff stud dogs from verified owners
Few breeds match the English Mastiff for sheer size, and that size makes sound joints and a healthy heart essential. On VerifiedStuds, every owner is identity verified, and each profile shows health results beside the fee. So you can compare Mastiff stud dogs on facts, not on weight claims.

Claim this spotMastiff stud fees usually run from $1,000 to $3,000. A health-tested male with no proven litters often asks $1,000 to $1,500. However, champions and proven producers from known lines can ask $2,000 to $3,500.
These are market estimates, since fees are private. Giant-breed litters are costly to raise, so many owners price near the value of one puppy. The stud fee guide explains contracts and return services.

The Mastiff Club of America is the AKC parent club for the breed. It recommends joint, heart and eye screening, along with several DNA tests. A stud can carry our Verified Health badge when the owner uploads these results:
Test
What we accept
Hips
OFA hip evaluation or PennHIP
Elbows
OFA elbow evaluation
Heart
Cardiac exam registered with OFA
Eyes
Exam by a board-certified ophthalmologist
Brucellosis
Negative test taken before the breeding
In addition, the club's list includes a patella exam, thyroid screening and DNA tests for cystinuria, dominant PRA, CMR1 and degenerative myelopathy. Owners can upload those too. Registered results are public on the OFA website.
See our health testing guides for how each test works.
First, look at how he moves. A good Mastiff is massive but never clumsy, with a level back and strong rear drive. Because the breed grows fast and carries great weight, sound hips and elbows matter more than extra pounds.
Next, ask about his heart and his family. Cardiac disease and bloat occur in giant breeds, and lifespans are short. Therefore, ask how long his parents and grandparents lived, and what they died of.
Finally, meet him if you can. The breed standard calls for dignity and good nature. A shy or sharp dog of this size is hard to live with, so temperament should weigh as much as type.
The Mastiff is one of the oldest British breeds, kept for centuries as an estate guardian. The AKC calls the breed courageous, dignified and good-natured. Males stand at least 30 inches at the shoulder and often weigh well over 160 pounds.
Despite that bulk, most Mastiffs are calm house dogs who bond closely with their families. However, they mature slowly. As a result, many breeders wait until a male is at least two years old, with final OFA results, before offering him at stud.
Mastiffs can breed naturally, but the size and weight of both dogs make it hard work. Therefore, many owners prefer artificial insemination, which is also safer for a heavy male's joints. Chilled semen is common too, because good dogs are spread far apart. Each profile lists the methods on offer.
The dog artificial insemination guide explains timing and shipping. Then see how VerifiedStuds works.

How much is a Mastiff stud fee?
Most owners charge $1,000 to $3,000. However, champions and proven producers can ask up to $3,500. These figures are estimates.
What health tests should a Mastiff stud have?
At minimum hips, elbows, a cardiac exam and an eye exam, plus a recent negative brucellosis test. The parent club also lists patella, thyroid and DNA tests.
At what age can a Mastiff be used at stud?
Most breeders wait until two years, because OFA gives final hip and elbow ratings at 24 months and the breed matures slowly.
Can Mastiffs breed naturally?
Yes, although many owners choose artificial insemination because of the dogs' size and weight.
Is the English Mastiff the same as the Mastiff?
Yes. The AKC registers the breed simply as the Mastiff, while many people call it the English Mastiff.
