Bullmastiff Breed Information

Breed Group: Working

Weight: Male 110-130; Female: 100-120 lbs

Height: Male: 25-27; Female: 24-26 inches

Color(s): red, fawn, or brindle

Overview

The Bullmastiff makes a great companion, and guard dog. Although intimidating at times, this breed can be very affectionate. Loving human attention, this breed is calm, gentle, and even-tempered.

Character

Being shy around strangers, this dog should be properly socialized during puppyhood. Used many times as an alert or guard dog, this breed should also be introduced to other animals at an early stage to avoid any altercations that may arise. The Bullmastiff is a powerful, yet at times docile breed.

Temperament

This willful dog requires a firm trainer to avoid any dominance issues. The Bullmastiff is fairly good-natured, sweet, and loveable, however this dog is not recommended for the average owner. His sheer size means he should not be placed in a home with small children as unintentionally, this breed can easily knock a child down.

Care

A firm bristle brush or rubber brush should be used on this breed occasionally to remove any dead or loose hair. Very little shedding, the Bullmastiff does not require much maintenance when it comes to grooming. As this dog does tend to slobber, the mouth should be regularly cleaned.

Coat

Having a great coat for weather protection, the hair on the Bullmastiff is very short. With a distinct black mask around muzzle, the coat on this breed should be dense and somewhat coarse to the touch.

Training

The Bullmastiff is sensitive to the tone of your voice, but should be handled firmly if this breed is to succeed in training. Can do well in obedience training, and does exceptionally well as a guard or watch dog.

Activity

A lazy breed, to avoid weight problems this breed should be sufficiently exercised regularly. The Bullmastiff does enjoy long walks or jogs, and would do well with an average sized yard.

No,typically no one does that to bullmastiff dogs. I have had several boxers and I clipped the 1st one ,but not any of the others. It really is a painful ordeal for dogs . I think more people have realized that with any dog . But ,I have never seen a bull mastiff with cippled ears. I ahve owned 3 of them and their hanging ears are what make them so gentle looking.( but most people are scared of them just for their pure size.

We crate trained our English Mastiff that we got when he was 6 days old. He was in the crate a lot at first, obviously. When he was old enough to we had him out of the crate when we were in the same room with him. If we had to leave he went back in his crate. As he got better at potty trainig he had a little more freedom, ex. we were in the kitchen and he stayed out if we had to leave the room or run outside quick. Even after he was 100% house broken he still slept in his crate until he slept through the night without have to go outside (about 6 months old).

Anonymous - 2/2/2012 12:47:03 PM

We trained our bullmastiff puppy by bringing him outside into the backyard and waiting for him to pee or poop...(around 20 minutes after eating a meal or drinking water) whenever he did we would act super excited and then give him a treat right away. It took less than a week for him to figure out to go out in the backyard. At first he would stand at the door when he had to go (we had to watch for it) but now at 14 weeks old he whines or barks at the door when he needs to go out...and we still give him a treat when he does. You need patience for the first few days when waiting to catch your puppy going in the yard but it is definitely worth it. Good luck with your puppy!

Anonymous - 10/17/2011 10:08:06 AM

You need to keep one regiment like crate training and stick with it. You need to make sure that when you feed your bullmastiff, take her out immediately and give positive reinforcement when she goes outside. Each day, make the interval of time longer and longer after meals and water --my dog is 5 months already and she is just getting the idea now---takes time but if you stay with it she'll gert it right5

QUESTION: We have a 2 1/2 month old Bullmastiff male puppy. He is very intelligent and responds very well to basic training (sit, down, come, run). He is terrific on that. The bad side is when walking on leash or just playing outside he will become very excited and jump up to bite us. He bites our legs, pant legs, whatever he can grap and he will growl at us. He is only 2 months old! What to do? We verbally scold him and shake scruff of neck to make him let go and then crate him. Any other suggestions? Thanks!

Anonymous - 8/29/2011 12:11:44 PM

Respond to Question

The turning your back and ignoring method works well with some things (like jumping), but I wouldn't recommend it to stop the bitting. In addition to clear/consisent verbal comments, I would grab a hold of his mouth and squezze it shut when ours did this..almost like an alligator in those tv shows. It may feel wierd at first, but we have ZERO problems with bitting now and ours just turned 2. He's very gentle when returning his toys for fetch or anything else involving "jaw control". We can even play around and mess his face, ears, food, etc and he doesn't try and bite at all. As you know, BM's get really big and huge mouths so you can't take a chance that they'll interept bitting/chewing/nipping as acceptable behavior.

Anonymous - 1/27/2012 3:13:03 PM

I had a similar experience with my bullmastiff pup. I interpreted it as a call for attention. I would try to discipline him like you but to no avail. I think he thought it was a fun game- him jumping up or biting my pants and growling and me responding by grabbing his neck and getting equally worked up. I found the best strategy was to simply ignore him, to teach him that this behavior would not get my attention. I would turn and give him my back until he stopped. Sometimes i would have to endure a minute of him grabbing my pants from behind, and I would circle around so my back was always to him. It took a great deal of patience but these outbursts eventually stopped. Also, to prevent jumping up try kneeing him lightly in the chest to make this activity uncomfortable to him. Good Luck.

QUESTION: I'm considering a bull mastiff but i'm concerned about living quarters. I've had large breeds in the past (lab, golden retriever, newfoundlander) that have had trouble with stairs in their old age. My new house enters at the basement level, then up 12 steps to the main living area and up another 12 steps to the bedrooms. I know that a bull mastiff puppy would have to be closely monitored on the stairs, but would this many stairs cause damage to an adult bull mastiff just from daily living? (i.e, dysplasia, back problems, etc.) Also my yard is literally just a patio approximately 10ft x 14ft, no grass but a high fence. I do however, live within 200 yards of a park. I love this breed but i don't want to get a puppy that is only able to live on the basement level of my home. It just wouldn't be fair.

A true Bullmastiff is a large dog. The standard set by AKC says that an adult, 3 years old, will weigh between 100#-130#. I myself am a Bullmastiff breeder and I have 2 females that weigh in excess of 130#, about 26" tall at the shoulder.

Respond to Question

As long as you teach your bullmastiff as a puppy that the little dog isn't a chew toy or something to be snacked on they should be fine. Our biggest bullmastiff and our tiny little mini dachshund are best friends - they play tug (usually the little one wins because the big one knows not to get too rough), they chase each other all over and they are always curled up right next to each other. Once in a while the big one will play a little rough or not watch where he's stepping and we'll hear a yelp but never anything serious and you can tell he is immediately sorry. Bullmastiff's are excellent with children and also little dogs - they are very gentle and know how rough or how gentle they need to be.

QUESTION: Hi, I have a 7 month male bullmastiff, who is about 30kg already. He is very energentic and boisterous and my issue is with exercise and his joints, I don't want him to do too much and damage them for later life. But he tears round the house and garden jumping up and off sofas, the decking, stairs, flower beds anything that is in his way, and on walks I keep him on the lead most of the way and let him off in one field because I think running on grass must be better than running on paving stones and tites at home, but he zooms round there for 20 minutes too. He has soo much energy. I tried to keep him on the lead and not allow him to run around the garden, but after an hour walk, he just ran around the room he was in, and played pretty roughly and destructively with anything or anyone in the room for the next hour. If he's off he zooms round for about 20 minutes and then is tired. Does anyone have joint saving ways of tiring him out everyday?

Anonymous - 7/18/2011 8:11:59 AM

Respond to Question

A great way to tire your bullmastiff out, but you have to do it slowly and carefully, is to train him to walk, then run on a treadmill. If you have a young dog it is fairly easy a task to do. The hard trick for me was teaching mine to let me slow it down to stop, not just jump off.

QUESTION: I am considering getting a Bullmastiff from a rescue, but am not sure how my living situation will work out. Out family lives on 36 acres of land total, but consists of three different households. They all let their dogs run free on the property, and have a lot of dogs (7 plus my son's Beagle puppy).

I would be very cautious of a rescue dog around children. You really do not know the dog's history or lines to know if it may have aggressive tendencies. I know a lady who is a handler for AKC shows and also worked with rescue bullmastiffs. She had one attack her at a hotel when she was picking it up from the rescue organization. She is left with major scaring and tons of surgeries.

Anonymous - 8/31/2011 10:42:41 PM

It really all depends on the dog's personality. Some dogs just grow up to be teddy bears and others grow up to be a bit aggressive. I have an intact male bullmastiff and I honestly don't think he could intentionally hurt anyone. I was a bit scared that not having him neutered would lead to a bit of an agressive streak but he is anyting but. He is just interested in getting his belly scratched and stealing my socks. When he is not in house protection mode, he is just friendly and welcoming to everyone, human and furry. I think I got a good idea he would be fine when I started giving him raw hides and stealling them back from him. I've been around dogs that would bite your hand if you got between them and their food but he would just give me a sad look asking me when I would give it back. He could definitley do some damage if inclined, but I don't think he is wired for it. Again, you just have to get a feeling for how the dog acts in various situations.

I would spay or neuter any dog I got even if it wasn't already simply because I have no desire to breed dogs. My neighbors do have a couple of females that they are breeding one more time, so we have to make sure all the males are fixed anyway. I also plan on getting a young dog when I do so any bad behaviors that have been learned can be corrected. I am not getting one any time soon, however, because I have two dogs right now, and cannot afford a third. My Yorkie, however, is getting very old, and I am starting my research on the different types of Mastiffs now so I can be well informed before getting one. I have loved Mastiffs since watching "Turner and Hooch" as a little girl, even though Hooch is a French Mastiff. I also LOVE big dogs. I figure, where we have the time to spend with them, and the room for them, we should take in lost souls that need someone who understands what they want and need. Thank-you all for your input!! It is much appreciated!!!

I am assuming that if you are getting the Bullmastiff from a rescue that it will be spayed or neutered? Also, what is the age of the dog you are planning on getting? Ask the rescue how this dog does with other dogs. We have several bullmastiff's that run and play with our bulldogs and our little dachshund and chihuahua. Most bullmastiff's do ok with other dogs as long as they are properly socialized with them. If it's coming from a rescue it is very possible the dog was not properly socialized as a pup and therefore wouldn't be a good candidate for your home - just ask first. Also, most rescue's will give you the option of bringing the dog back if it doesn't fit into your home due to issues like that.

When my husband and I moved into a different house our bullmastiff had a difficult time adjusting. Try giving her some treats and lots of attention! But what really worked for me was cutting up food and mixing it in with his dog food. Now I know not everyone gives their dog "human food", but I gotta say it definetly works. Keep it simple like some lunch meat, bread, and cheese. If nothing else works warm up some cheap hot dogs and let the smell fill up the room, she'll be drooling and bagging in no time! Good Luck
