English Mastador Dog Breed Information

An English Mastador is a cross between an English Mastiff and a Labrador Retriever. English Mastaor puppies will grow into huge dogs that are known as gentle giants. They are affectionate, loyal dogs that are protective of their families.

Although they are not recognized by the AKC, they are recognized by other notable dog registries. The American Canine Hybrid Club, International Designer Canine Registry, and more all recognize the English Mastador.

English Mastadors tend to be loving and affectionate with their families. They thrive on attention from their favorite humans and love to be involved in family activities. They tend to get along well with children, other dogs, and other pets.

Because of their protective instinct, they are naturally wary and suspicious of strangers. As long as they have been properly socialized, they will warm up once introduced and will be happy to observe interactions and receive attention.

The English Mastador is a moderately adaptable dog. Although they can adapt to apartment living, their huge size is definitely a limitation. Their size generally makes them better suited to larger homes.

They are sensitive to heat, but do relatively well in cooler temperatures. If you live in an area with harsher winters, you may need to pick up some winter dog products to keep them warm while out on walks.

Potential health concerns to be aware of in an English Mastador include cataracts, elbow dysplasia, and hip dysplasia. Reputable breeders will screen their dogs to avoid passing preventable issues to puppies, so make sure you ask about the parents.

These big dogs are also prone to weight gain. As a giant dog breed that is already prone to joint issues, it’s important to make sure they eat a healthy diet and get enough exercise.

They are also one of the breeds at risk of bloat, which becomes quickly dangerous and fatal if gastric torsion occurs. Knowing how to reduce the risk of bloat and knowing the symptoms means you can get help as quickly as possible.

Although these dogs are intelligent, they also tend to have stubborn and independent streaks. This can be challenging for first-time dog owners. So, puppy training classes are recommended, especially because these puppies will grow into such big dogs.

English Mastadors have a short coat that will shed moderately year-round. Weekly brushing or brushing a few times a week along with a bath as needed can help keep this dog’s coat healthy and looking great. They will also tend to drool, so you may want to have a drool cloth on hand.

In addition to coat care, you will also need to take care of your English Mastador’s nails, ears, and teeth. Cutting nails once or twice monthly keeps them from growing too long. Weekly ear checks and careful cleanings as needed helps prevent ear infections.

Brushing teeth daily or using an enzyme toothpaste every day helps prevent painful dental diseases later in life. Doing this, in addition to cleanings at the vet as needed, is ideal dental care for dogs.

An English Mastador is a mix of a low-energy and high-energy dog. They generally sit in a more moderate range, but you may see some bursts of lower or higher energy at times. For the most part, daily walks plus some more rigorous exercise throughout the day is enough to keep this dog happy and healthy.

Fully-grown English Mastadors usually stand 28-36 inches tall and weigh 85-160 pounds. But, some have been known to tip the scales at 200+.

English Mastadors generally live for 10-12 years on average.
