Male vs Female Bullmastiff: 4 Key Differences

Without a doubt, one of the most magnificent dog breeds around today is the bullmastiff. These big canines were developed to be defenders by English gamekeepers in the 19th century. The breed is descended from a cross between 40 percent bulldog and 60 percent mastiff. Bullmastiffs are becoming a popular option for people seeking a dependable, amiable, and protective dog. They are kind, devoted, and vigilant—all the traits of an excellent family dog. Prospective bullmastiff owners might be wondering if female bullmastiffs are different from male bullmastiffs as they get ready to adopt their new member of the family. Let’s examine the four main distinctions between bullmastiffs of the sexes.

1. Height

Because bullmastiffs are sexually dimorphic, the male and female breeds differ greatly in terms of size and appearance. This attractive breed’s males are typically a little taller than the females. Females are 24 to 26 inches tall, while they develop to be 25 to 27 inches at the withers, or shoulders. The males are even larger than the already enormous females!

2. Weight

The disparity in weight between the sexes corresponds to the differences in height. A healthy adult bullmastiff female weighs only between 100 to 120 pounds, compared to the 110 to 130 pounds that a healthy adult man weighs. Even while a 10-pound size difference might not seem like much, it’s something to think about if you want to acquire a bullmastiff.

Keep in mind that a dog’s optimal daily food consumption varies depending on its weight. Large dogs over 100 pounds should be fed an extra 1/3 cup of food daily for every 10 pounds of additional body weight. This indicates that an adult male bullmastiff may consume around 2 1/2 pounds more food on average per week, roughly 10 pounds more per month, and ultimately 122 pounds more food annually than a female bullmastiff. Whichever sex you decide to adopt, be sure you have all the necessary funds to cover the expenses of caring for a huge dog.

3. Build

The bullmastiff is a large canine with a square, broad head and a tight, powerful build. Bullmastiffs, both male and female, have a robust appearance, and it can be challenging to tell them apart just by looking at their physique. But because she’s a little smaller than he is, the female’s build is often a little more tiny than his. Don’t be misled: female bullmastiffs still have a frightening aspect while having a little smaller build.

4. Temperament

Bullmastiffs exhibit some gender-specific temperamental characteristics, much like many other dog breeds. Generally speaking, females exhibit less dominance and men are more aggressively territorial. Males tend to be more playful with their owners, but females may be more gregarious. Dogs have dynamic personalities that depend on a variety of circumstances outside of their sex, so it’s crucial to keep in mind that these are generalisations.

Regardless of your pet’s gender, there are certain things that have a big impact on its temperament and behaviour. By nature, bullmastiffs are calm and self-assured. Given their intelligence, it is imperative that both men and females receive early instruction and socialisation. Keeping multiple bullmastiffs of the same sex might cause extreme aggression, according to some bullmastiff owners. These reports, nevertheless, are anecdotal and have not yet been verified by science.
