We are lovers of the English Mastiff breed and have several of our own mastiffs (and a few other pets) in southwestern Michigan. Some might think we're nuts, but our animals are ALL inside-although they regularly romp their 5 acre plot running after frogs, and after the cranes and the geese that fly by.
At 3, Voltaire is 230 lbs. He is 34 inches at the shoulder and is still growing. He was Penn Hipped on September 14th, 2007 and there is no evidence of djd (degenerative joint disease) or cavitation. He was cerf'd and cardiac cleared November, 2008.
Billie is 165 lbs. and is 28 at the shoulder at 5 yrs. She was Penn Hipped on September 7th, 2007 and there is no evidence of djd (degenerative joint disease) or cavitation. Her grand-dam was 220 and and she is throwing large pups based on those and Voltaire's genetics. We are currently beginning to breed some of her girls.
Macy, Athena, and Jasmine are all large and beautiful siblings who have been kept back for our breeding program. All are 2. Athena and Jasmine are about 30 inches and are both in the 170-180 range. Macy is almost 34 inches and is about 160 right now. ALL these girls are still maturing/growing.
All of our pups come with a 2 year written health guarantee, are vet checked, have their 8 week puppy shots, and are microchipped. Our animals are our babies and we treat them that way. Our litters are limited and we only place pups in homes that plan on treating their mastiff lovingly and as a member of their family. If you are interested in one of our puppies, please fill out the mastiff questionnaire and we will add you to our update list.
We hope this site will give you some useful foundation information on the English Mastiff and a great idea of the lines our babies come from. We certainly enjoyed creating it! Please feel free to contact us anytime to talk "Mastiff". The quickest way to contact us is by emailing us at dfranke716@hotmail.com. You may also try our home at 269-763-3836 or our cell at 269-908-2680.

Hercules - Our Mastiff mascott Shih Tzu
| and now a word from our SEO company
Welcome to the home of the gentle giant. We are Michigan’s premier Old English Mastiff breeder and take extreme pride in our Mastiffs. Here at Thunder Run Mastiffs, we are dedicated to breeding quality, champion English Mastiffs that are not only the best in show, but are also truly man’s best friend.
English Mastiffs are the biggest dogs known to man and they have some of the best temperaments of any breed. They are extremely calm and gentle, making them the perfect family pet. Originally bred to be guard dogs, Old English Mastiffs have a true family orientation that makes their desire to bond and their drive to guard and protect even stronger. Our Mastiff Stud Voltaire is the sweetest dog on the face of this earth, but at his 230-pound size no stranger is comfortable entering our yard without us present.
Mastiffs are a very versatile breed. They are great for a single person home where they get a lot of one on one attention, or for a big family where they can become one of the gang. Mastiffs are a loyal and protective breed, making them great for families with children. Our mastiffs range from 150 to 250 pounds and come with a 2-year health guarantee for your peace of mind, although their lineage already predisposes them to a healthy, long life.
If you are looking to bring a Mastiff into your home, there is no better breeder to choose from than Thunder Run Mastiffs. All of our dogs live inside of the house and are free to roam our five acres of land with supervision. We treat all of our Old English Mastiffs as if they were our children, ensuring they become great lifelong companions for our adoptive families. Our English Mastiffs will make the perfect addition to your family.
Here you will find all the information you need for choosing your next pet. There are pictures and bios of all of our dogs so you know exactly where each of our puppies comes from. Take a look at the pictures of the mastiff puppies who are waiting to become a member of your family. We often have English Mastiff puppies for sale through our adoption process.
We are located in Southwestern Michigan, but have English Mastiff puppies living all over the United States and Canada. We ship semen from our English Mastiff Stud worldwide. Please visit frequently, as we are always updating our site with available litters. We look forward to speaking with you on how an English Mastiff puppy can become the newest addition to your family.
