Bullmasador Breed History

Bullmasadors are quickly gaining popularity but do not have a known history. However, we do know that they were created by crossbreeding two very well known dog breeds. The Labrador Retriever is one of the most known and popular dog breeds in the United States. At one point, they were called St John’s Dogs. This breed is native to Newfoundland where they were often used by fishermen. Their duties included retrieving fish that escaped from the lines as well as helping to pull in the nets. In the 1800s, some English ships returning from Labrador brought a few of these dogs to England. Setters, some types of Retrievers, and Spaniels were bred with these dogs with the goal of improving their hunting skills. Today, this breed is very well known and is quite diverse and talented at many sports and activities. Aside from hunting, they excel at police work, retrieving, tracking, detecting narcotics, being watchdogs, guiding the blind or being service dogs for disabled people, carting, agility, sledding, search and rescue, competitive obedience and field trials. Bullmastiffs are a breed created from 60% Mastiff and 40% Bulldog. Their creation took place in England and dates back all the way to 1795. They were originally used to track, tackle and contain poachers for gamekeepers. Although they were intimidating and strong, they would be trained to not harm the intruders. In the modern day, however, these dogs are known to be great watch dogs, family companions and guard dogs.

Bullmasador Breed Appearance

These dogs, which can be found in red, fawn, brindle, light brown or black with white markings, and chocolate, have dense, shiny and short coats. Their fur is also water repellent and can have several markings, including tuxedo, tri-color, brindle or simply a solid color. Their fur is water repellent and double layered but sheds minimally. They have floppy ears that point downwards and fearless eyes. These very large dogs are about 23 to 29 inches tall and anywhere between 70 and 180 pounds will be a healthy weight for these dogs. They have muscular bodies and thick necks that are very strong. Their faces will be sleek and the tails will be long. These dogs might also take on some characteristics from the Bullmastiff and the Labrador Retriever. To find out more possible options of how this breed will look, research the appearance of the two parent breeds.

Bullmasador Breed Maintenance

The Bullmasador is a dog that sheds lightly and has a coat that will be easy to maintain. Aside from needing the occasional bath maybe once a week, as well as brushing twice a week, this breed is quite easy to maintain. All breeds should have their ears cleaned weekly, but especially the Bullmasador, since they are prone to ear infections. Do not let them stay outside for too long when it is very hot out, as these big dogs are prone to heat stroke. Some people choose to get kiddie pools for their Bullmasadors to help keep them cool during the hot summer months. All dogs need to have their teeth maintained, as well as their nails. Brush your dog’s teeth every day, or two or three times per month as a minimum. Your pet should also have their nails clipped once or twice per month. However, some dogs will need to have their nails trimmed less often if they are active and wear them down naturally. If you can hear your Bullmasador’s nails clicking on the floor when they walk, the nails are definitely too long and need to be cut.

Bullmasador Temperament

These dogs will have the smart and calm temperaments of a Labrador Retriever with the size and strength of a Bullmastiff. They are big and strong dogs that are loyal and will be undeniably faithful to their owners. They are also gentle and protective towards children, which makes them great family pets. This breed loves to please their masters and, due to their high intelligence, they will be easy to train. However, they are very large in size and may be a handful for an owner who is not experienced with dogs. To train and socialize this breed, you must be consistent, patient and sure to reward them for their good behavior. They are devoted to their families and will make great watchdogs that will alert you at the first sign of anything unusual. With proper socialization, these dogs will probably be good around other pets as well.

Bullmasador Activity Requirements

This designer breed is very active and will need a big yard to run around in. However, do not overwork or keep them outside for too long in the heat as they can easily develop heat stroke. The Bullmastiff generally needs 30 to 45 minutes of daily activity, and the Labrador Retriever does well with around an hour of exercise, we can conclude that the Bullmasador will need around 30 to 60 minutes of activity every day.

Jas was a rescue runt from a litter with a bull mastiff mom and lab dad. She's on the small side for this breed, weighing right around 70#. She has been great with the kids, and although she's lazy, she will go for walks, hikes, or run along with the kids. She also only ever barks for a reason and doesn't need a fence to stay around. Very sweet dog,we would definitely get another bullmasadar.

Sarge is extremely intelligent. He is protective to our home, our children, and adults. He is affectionate and takes up half our bed. He understands sit, stay, no, lay down,settle,walk,ball, park,back, stop, potty, go outside, Bye-Bye, bone, snacks, and bedtime, all by the age of 6 months! He is still a bit over active at playtime however settles down when asked. He likes to rough play with our Labrador "Major". He is loving, and makes us laugh all the time. He is a very good jumper and loves high energy exercise. He has an amazing personality, loves to cuddle, and is very keen on his environment (he does not like changes.)Nor does he enjoy bathtime.(but he will peek his nose under the curtain to see what you are doing while you are in the shower...) He is one of the most intelligent dogs I have ever owned, and we love him so much!

Very affectionate and sensitive. Doesn't like being yelled at or very loud noises he gets his feelings hurt easy. He's extremely smarty and knows the difference between similar words like no, stop, out and go. He catches on very quickly with sit, shake, and lay down. He's a loyal friend and gives hugs when I cry, he follows me room to room and is great with all the kids in my family that visit. He's a great dog!
