Mastadore, Mastidoor

The Mastador is a designer dog, an intentional cross between an ancient guarding breed, the English Mastiff, and the Labrador Retriever, a dog that has spent the last quarter-century in the top spot for popularity according to the American Kennel Club. The resulting hybrid is a very large and friendly animal who can be particularly animated during their younger years. Although they are generally amicable with most people and animals, they usually retain enough protective instincts to make an excellent watchdog, and are fairly easy to train, although some may tend towards stubbornness. Early training and socialization will help this canine to become an outgoing and dependable member of the family.

Mastador Breed History

 The Mastador is a hybrid animal, a cross between the Labrador Retriever, a gun dog that specializes in retrieving waterfowl, and the English Mastiff, an daunting giant of a canine who is surprisingly good-natured. Mastiff-type dogs were even recorded as marching alongside the armies of Hannibal when they crossed the Alps and have been depicted in ancient stone and artwork thousands of years old in Mesopotamia and in Asia. As consummate guard dogs and excellent hunting companions, they quickly became valued for their steadfast natures as well as their easy-going temperament by both the peasants and the wealthier landholders throughout England. World Wars I and II had a catastrophic impact on Europe’s canine population, and the largest dogs such as the English Mastiff were the hardest hit. Their size put them in double jeopardy, making them both difficult to feed during times of rationing, and attractive as military dogs, employed to pull munitions carts out to the front lines, a dangerous and sometimes deadly job. Once both of the wars had finally ended the English Mastiff breed had become nearly extinct, at one point reduced to just fifteen dogs known worldwide that were suitable for  contribution to the gene pool. Mastiff puppies were imported to England from both the United States and Canada to help revive the breed, and they resurged in popularity, capturing the spot of the 28th most popular breed according to the AKC. The Labrador Retriever also has a long and somewhat uncertain history, portions of which we can only guess at. Experts are generally in agreement that the St. John’s dog, a water dog that became extinct as recently as the 1980’s, was the foundation breed that was used for the Labrador Retriever breed, but not much is known about how the St. John’s dog came to be. The St. John’s dog worked alongside fishermen that worked the coasts of Newfoundland and with its short, oily coat was as at home swimming in the water as it was running on land. The St. John’s dogs, like the Labradors, were retrieving dogs, although they specialized in retrieving fish, nets, and ropes from the water, rather than collecting the waterfowl that the Labrador was bred for. In the 1800’s James Harris and Walter Scott were fortunate enough to meet while out shooting.  Both men had been breeding specific St. Johns dogs for their suitability as gun dogs and when Mr. Harris gifted of two of his male retrievers to Mr. Scott, Mr. Scott bred them to his own dogs, giving rise to today’s modern Labradors. 

Mastador Breed Appearance

This combination of breeds produces canines that are quite large, generally in the 85 to 160 pound range, with long legs and an athletic build. They have wide heads, although narrower than the head of the English Mastiff, and while the exceptionally short muzzle of the Mastiff is sometimes passed down, the square, medium-length muzzle of the Labrador is seen more frequently. The Mastador may have some wrinkling around their muzzle, their almond-shaped eyes can range from a dark brown that is nearly black to hazel, and their triangular ears have rounded tips and hang down close to the sides of their head, framing their face. The coat of this crossbreed is double layered, consisting of a water-resistant, dense undercoat which is overlayed by a short, relatively coarse layer of straight fur that lies close to the skin, although the Labrador Retriever heritage may sometimes contribute a slight wave in the coat.  Mastadors usually come in solid colors, with differing shades of black, brown, and golden, and they often have black or white markings on their feet and chest. Black face masks are also commonly passed down to the Mastador from the Mastiff.

Mastador Breed Maintenance

The Mastador doesn’t have extensive grooming needs; their coats are generally short and stiff, making them proficient at shedding dirt and water, so in ideal conditions, they should only need bathing a few times a year. This dog, being very athletic and a lover of water, may have a yeast or bacterial buildup within the ear if not checked; twice weekly cleaning and drying of the ear at minimum is recommended and even more often if your Mastador is a daily swimmer. Due to his very active nature, observing his gait and looking at the condition of the footpads should be included in the grooming routine. Weekly brushing will help to distribute the dog's natural healthy oils throughout the coat as well as remove loose fur.

Labrador Retrievers and Mastiffs often suffer from dilated cardiomyopathy, pulmonic stenosis, and eye conditions. Secure pet health insurance today to avoid high veterinary care costs.

Mastador Temperament

This crossbreed is typically a friendly and social breed, although they may be more reserved than outgoing, and some protective instincts are likely to be passed down through the Mastiff breed. The Mastador is a very large and powerful canine that can be a bit rambunctious, particularly during their long adolescence, and any interactions between children and these dogs should be closely supervised to prevent muscle and joint strain on the part of the dog or bumps and bruises on the part of the child. These large to giant-sized dogs are generally friendly and gentle towards strangers and other animals as well, but proper socialization and early training will help to fully cement these tendencies and to prevent any shyness, timidity, or aggressiveness from taking root. This canine should be very trainable in most cases, particularly if the training is started early in their lives, however, stubbornness can be an issue and patience will be required. 

Mastador Activity Requirements

The Labrador Retriever is an active and athletic dog breed that requires a great deal of exercise each day. Fortunately for the owners of Mastador hybrids, the Mastiff is a much more placid canine and they don’t require nearly as much activity as the Labrador Retriever. In the majority of cases, this particular crossbreed is content with about an hour or so of vigorous activity. Labrador Retrievers and Mastiffs are both known for boisterous behavior when they are young and although the Mastiff usually outgrows this stage, some Labradors continue to be spirited throughout their life. It is important to remember that overly strenuous activity and activities that involve jumping or leaping can cause stress and damage to the joints of very large and giant sized dogs like the Mastador. Even if they canine does not appear to be worn out walks should be frequent, but they should be kept relatively short. Care should be taken to reduce strain on growing bones and joints at every opportunity; a nice long walk without impact will please the Mastador. This dog requires a great deal of room and while some mature candidates may be able to adapt to apartment life, most are too active and are better able to thrive in a larger space with a yard.

Unfortunately my girl was not well socialized as a puppy by the breeder or possible bred without concern for parents temperament. She has severe anxiety with new people and places. It’s very sad she’s unable to go on walks or enjoy any company we have over. She gets aggravated with anyone coming in the house that isn’t family. I’ve spent thousands of dollars on vets, trainers, behaviorist with little improvement. We love her and she’s fine with just us but I’m very disappointed with the breeder. The only dog I’ve very had that wasn’t a rescue ends up being the most challenging. My advice don’t by a puppy without meeting it first. A puppy needs to come to you with ease.

My sister in law had to move from a house to an apartment and could only bring 1 dog. She told me, please take her. I wasn't going to until Ella came over and laid her face on my lap and looked at me. I took her. For such a big dog, they are so loving. No for smaller kids or elderly people. Reason why, sometimes they get so excited to see you they jump on you. 130 lbs is no joke!! I love her

He is afraid of being alone at night, I don't mind just means more snuggles for me. He is great with my other dog who only has 3 legs.

Baloo got almost all of his traits from the mastiff. The stubbornness being number one. But with a little patience and time he has learned quite a lot. He currently has a good bit of energy but I believe that is just the puppy in him. He will still lay down on the couch with me after play time and cuddle while we watch tv. He has just turned 6 months and is 24” tall at the withers and weighing in at 67lbs.

What a happy boy. Loves to snuggle especially after walkies or playing with his doggy pals. I was nervous living in an apartment but as long as they are exercised and entertained they are sweeties. Loves his toys and bones. Mine definitely leans more towards a retriever with his social side but mastiff with his size and slobber. Taught him 'paws up' in 20 minutes. Also hates car rides. Wouldn't trade him for anything

Saved from the pound in St. Saint Marie on a work trip. Skinny, beat up, bad owners. He has turned into my best friend. I call him my Wall Mart greeter in the dog park. Has to go say hi to everyone. Never aggressive and loves to play and run. If the other dog likes a good game of chase they are best buds. If not he just goes his own way to find another friend.

I got him as a puppy and it was love at first sight between him and my youngest, they’re about the same age and she’d scoot him on her lap so she could hold him. He gets along phenomenally with everyone, he absolutely adores children and being beside you at all times. His favorite pass time is playing with balloons with the kids (they like to see how long they can keep it from touching the floor which he has picked up on and tries to do it as well) he gets along great with other animals, everything is a friend to him😂

She has been hard to potty train as we live on the 3rd floor… but she is VERY good motivated and has just now gotten the hang of holding it until she gets down the stairs. She is very low energy with burst of puppy energy. She is very social as we make sure she meets new people everyday because she is so calm she is getting trained to come into my memory care to provide pet visits to residents. She is good with distractions and knows how to sit, lay down, leave it, go to your place (she’s crate trained), sits when waiting for someone to pet her, and to wait. She also has a keen since when my anxiety gets high and will calm down and come out her head on me when I start to get overly anxious. She is the best dog ever.

hi there i have a new mastador and she just melts me and my fiances heart. we got her at 7 in a half weeks and have had her for 15 days now. shes already going to the bathroom outside, will already let me know in the morning she needs to go out. there is an occasional pee on the floor which is expected. shes on puppy chow right now. my question i guess is when should i change to a better quality food, and can i mix good meats and veggies in with her food. do they like fish? i want her nutrition to be top notch. if you could get back to me at your earliest convienience that would be great -nick

Answer
Ideally she would be fed a commercial balanced puppy diet that contains all of her vitamins and minerals. As she is a large breed, she should be fed a diet specific for larger dogs as their calcium requirements are high. Good options include Royal Canin Puppy Maxi and Hills Large Puppy. If you choose to, you can add vegetables, fish and meat but this isn't necessary and can cause fussiness in some pups (who will start to eat the human food and not their own kibble!).
