Don’t you just hate when your guard dog mauls an intruder? Well, so did the English elite of the 19th century. The Bullmastiff were bred from an Olde English Bulldog and a Mastiff. This created the perfect pup that would merely detain the would-be thief for questioning. Surely this was a much kinder fate for these miscreants but the idea of being detained by a Bullmastiff is truly chilling.

While “on the job” these pups are fearsome, at home they are calm, cuddly, and deeply devoted to their people. The Bullmastiff, however, is not for everyone. This pup is best suited to a household where the owner is the clear alpha. With a clear pack order set in a loving household, a Bullmastiff will thrive. These pups have a keen ability to sense strangers who mean to do harm versus friends who they just haven’t met yet.

Fun Facts

In the 1920s, John Davison Rockefeller, an American industrialist, used Bullmastiffs to guard his New York estate.


Bullmastiffs are prone to several hereditary conditions, always request proper screening from your breeder before you bring a new pup home. Some health issues can include hip dysplasia, elbow dysplasia, cancer, entropion, progressive retinal atrophy, ruptured cruciate ligament, and ectropion.

While you always hope your pet will live a long and healthy life, it is always a good idea to invest in pet health insurance.

Keeping your dog’s mouth clean and problem free goes a long way to your pup’s overall health. Dental hygiene can be the cause or can be the byproduct of other serious health issues.

Visual inspections can be performed to keep track of the signs of potentially waning oral health. These signs can be anything from bad breath to abnormal chewing to loss of appetite.

Keeping ahead of these warning signs can pay dividends. A preventative approach can delay and stop many of the common dental problems from arising.

Oral health can be tackled in five basic steps:

  1. Brushing your dog’s teeth to prevent an undesirable buildup of plaque
  2. Feed your dog a diet where the high quality dog food has dental benefits
  3. Regularly give your dog dental toys and treats
  4. Use mouthwash, to help where brushing misses
  5. At the sign of any abnormalities, consult a vet. You can even do it virtually, from the convenience of your home.

Dogs are just like humans in that they can experience anxiety. The degree to which they are susceptible to anxiety and how they deal with anxiety is breed specific. Left unchecked, initial signs of anxiety could give way to an anxiety disorder. The symptoms of anxiety disorders can lead to a myriad of behavior issues.

Knowing the signs and symptoms will best equip you to keep ahead of it and to nip it in the bud at the earliest signs. There are options available to help with anxiety.

Bullmastiffs should be brushed with a slicker brush at least once every two weeks. While these pups are not heavy shedders, brushing will help remove any debris and dead hair and redistribute naturally occurring oils. During seasonal shedding periods, more frequent brushing will help contain the hair loss. Bathe your pup once every 3 months, or if he gets exceptionally dirty. Over washing will lead to dry and irritated skin.

Trim your pup’s nails regularly. Keep your pup’s eyes and ears clean and clear of debris. Brush your pup’s teeth several times per week.

Plan on spending 30-45 minutes in exercise with your pup each. Always keep your pup on a leash or in a securely fenced area. This breed can be aggressive with other pups and keeping him connected to you is always a good idea. Brisk walks and outdoor games are the best options for this pup. Puppies will have an extraordinary amount of energy, so be mindful to avoid overexercising which can lead to joint and skeletal issues as they grow. As your pup grows, he will become calmer and, in some cases, sedentary, requiring you to encourage your pup to exercise. Bullmastiffs are prone to overheat, be aware of the outdoor temperature when you are playing with your pup.


Your full-sized Bullmastiff will eat around 3 cups of food per day over 2 meals. This breed is prone to bloat which is an immediately life-threatening condition where the stomach overfills and flips in the torso. You can help avoid this situation by monitoring the rate at which your pup eats. The exact amount of food your dog will need will vary depending on age and activity level.

As with all dogs, early socialization with humans and other dogs is essential. Begin training your bullmastiff as soon as possible. It is much easier to leash train a small puppy than a 100lb pup. You must establish a firm pack order in your home. A bullmastiff cannot be permitted to believe he is the alpha. A meek owner will only face problems. You can establish this order while still conveying love to your pup through positive reinforcement training.

Proper training is essential to ensuring the safety of your dog and those around you. Having your dog come when they should, and in general having them listen is something you want to address early in your pup’s life, as it will pay dividends down the line. There are many tried and true training programs to accomplish this training – faster and better than you might think!

Unless you’re living on a farm, or have the space, a yipping dog, or one that barks all day when you are gone could be an issue with the neighbors and/or landlord. Historically, dogs would bark to communicate with the rest of the pack when hunting and bark as a warning shot to predators eyeing up their flock. Barking is deep rooted in dogs and manifests itself in many ways and for a variety of reasons.

Just like any habit or instinct, there are effective ways you can train this issue away.

Ensuring a comprehensive preventative vitamin and mineral plan is essential to keeping your dog healthy. Truth is, there are vitamins and minerals that your dog needs, but doesn’t produce naturally. While many of these vitamins and minerals can be found in your dog’s current diet and dog food, the question becomes, are there enough vitamins to ensure they aren’t deficient.

Poor nutrition can lead to some of the most common health issues, such as weak joints, compromised immunity, increased allergies, and low energy.

Vitamins play a vital role in your pet’s health and overall life expectancy. Here are some multivitamin and joint relief options.
