ENGLISH MASTIFFS

Our English Mastiffs are simply amazing!  They have great looks to go along with their wonderful personalities.  They are big, loveable dogs that just want to be your best friend. Our sires are shown below.  We have raised several generations of our Mastiffs so we know the health, temperament, size, and personality of our dogs.  We are proud of the fact that we have long, healthy lives with our dogs.  Our males typically grow up to weigh between 185 to 210 pounds when full grown but some are bigger.  Females typically weigh less than males. If you haven't been owned by a Mastiff before, you will be amazed by their personality. They are smart, loyal, eager to please, loving, and always ready to snuggle.

Our puppies will go to their new homes with all age appropriate vaccinations and dewormings, all health records, a one year health guarantee, they will be microchipped, will receive a complete veterinarian checkup, will  come with their AKC registration papers, and a certificate of health issued by their vet. 

We do genetic health testing on our dogs including eyes, hearts, patellas, degenerative myelopathy (DM),  Canine Multifocal Retinopathy (CMR1), Dominant PRA (PRA-D), and Hyperuricosuria (HU).

Below is some important information for new Mastiff owners!! Please read this and view the photos below to be prepared to give your new puppy the best chance at a wonderful life.  

When you get your 8/10 week old puppy, please keep this in mind. Their bones do not even touch yet. They plod around so cutely with big floppy paws and wobbly movement because their joints are entirely made up of muscle, tendons, ligaments with skin covering. Nothing is fitting tightly together or has a true socket yet. When you run them excessively or don't restrict their exercise to stop them from overdoing it during this period you don't give them a chance to grow properly. Every big jump or excited bouncing run causes impacts between the bones. In reasonable amounts this is not problematic and is the normal wear and tear that every animal will engage in. When you let a puppy jump up and down off the couch or bed, use stairs, take them for long walks/hikes, you are damaging that forming joint. When you let the puppy scramble on tile with no traction you are damaging the joint. You only get the chance to grow them once. A well built body is something that comes from excellent breeding and a great upbringing-BOTH, not just one.  Once grown you will have the rest of their life to spend playing and engaging in higher impact exercise. So keep them calm while they're still puppies and give the gift that can only be given once. Mastiffs grow quickly but for a long time.  They reach their full body height and length at around age 2 to 2 1/2 years.  They begin to fill out and get thicker and heavier after that.  Most will reach their full weight potential at around 5 years of age.
