We hope that these Better-Pet Scores will provide you with more insight into deciding which pet to get between the Bullmastiff and the Leonberger.

Bullmastiff versus Leonberger: Overview

Both the Bullmastiff and the Leonberger are similar in size. The Bullmastiff and the Leonberger are both giant-sized dogs.

This means both the Bullmastiff and the Leonberger were developed to assist humans in some capacity – including pulling sleds and carts, guarding flocks, guarding homes, and protecting their families.

Because of their size and strength, working dogs require a structured home life and firm, fair, consistent training by someone who can provide leadership without resorting to anger or physical force.

Bullmastiff versus Leonberger: Comparison Table

The table below compares the Bullmastiff to the Leonberger based on different important factors such as Price, Health, Kid-friendliness, etc.

When a dog breed scores higher for a factor than the other dog breed, the box of the breed that scores higher is shaded green and the box of the breed that scores lower is shaded red. When there is no difference between the breeds for a particular factor then the box is shaded gray for both pets. Also, when the factor is not important in picking a pet, or when the factor cannot be compared between two pets, the box for the factor is shaded gray for both pets

Most of the factors in the table for each dog breed are ranked on a scale of 1 to 5. “1” means “worst”, and “5” means “best”.

However, some factors such as “Price”, “Average Lifespan”, etc. cannot be on a scale of 1 to 5, so they are not on a scale of 1 to 5 in the comparison table.

Later in this article, we will further explain each factor as it applies to the Bullmastiff and the Leonberger

We call these total scores the Better-Pet Scores, as we mentioned earlier. We called this score the Better-Pet score because the better dog breed will have a higher score. This is because the pet will the higher score will have minimal needs and be easier to have as a pet.

    Although we have done our best to analyze these two dog breeds in a very unbiased way, however, we will like to let you know that there are some dog attributes that cannot be assigned a number for comparison. We cannot put a number on how cute a dog breed is, for example. Beauty is in the eye of the beholder.

    Also, the dog breed that best suits you will depend on your peculiar lifestyle, your taste, and your priorities, which we do not know. So, for you to decide on which breed is right for you, read through the rest of the article to further understand both the Bullmastiff and the Leonberger so that you can make your own well-informed decision on which pet to get.

    Note that a lot of factors determine how much you can expect to pay for the Bullmastiff puppy or the Leonberger puppy. This includes if health screening tests have been performed on the puppy, if the puppy is from a famous pedigree, the US State where the puppy is bred, etc.

    Nevertheless, when looking to buy a puppy, look at buying a puppy only from well-established breeders that breed puppies primarily for the love of dogs, and secondarily for profit. Do not buy a puppy from a puppy mill. Puppy mills mass-produce puppies in bad living conditions for maximum profit.

    You may also consider adopting a dog instead of buying a dog.

    Health Problems of Bullmastiff versus Health Problems of Leonberger

    Every dog breed has its own set of health problems that it has a tendency to develop. There is nothing like a perfect dog breed.

    Both the Bullmastiff and the Leonberger are prone to certain genetic health conditions. The Orthopedic Foundation for Animals (OFA) is the organization that keeps track of health problems in dogs. Based on the extensive records that the OFA keeps, the OFA knows what health problems each dog breed is naturally prone to develop. Hence, the OFA recommends which health screening that breeders should perform on a dog breed to make sure that the breeders won`t breed `defective` dog parents that can pass down defective genes to their puppy offspring.

    The more health problems a dog breed is prone to develop, the more health tests the OFA will recommend for that dog breed.

    Based on our review of OFA records, we found that the Leonberger is prone to more genetic health problems than the Bullmastiff.

    This is because the OFA recommends more screening health tests for the Leonberger than for the Bullmastiff.

    6 health tests are recommended for Bullmastiff while 10 tests are recommended for the Leonberger.

    Below is a detailed discussion of health problems in Bullmastiffs and in Leonbergers.

    Bullmastiff Health Problems

    Bullmastiffs are genetically prone to certain health problems. However, breeders can reduce the chances of producing Bullmastiff puppies with genetic defects by making sure that a puppy`s parents are free from genetic health problems before allowing the parent to make puppies.

    The OFA provides breeders recommendations on which genetic diseases that breeders should screen their dog parents and puppies for.

    If you want a Bullmastiff puppy that will grow up to be healthy, make sure that your Bullmastiff breeder screens your puppy or your puppy`s parents for the health problems that the OFA recommends for your puppy`s breed. This will increase the chances that your puppy is free from genetic defects.

    The following are the health tests that Orthopedic Foundation for Animals (OFA) recommends that breeders should screen Bullmastiffs for:

  • Autoimmune thyroiditis
  • Cardiac Evaluation
  • Elbow Dysplasia
  • Eye Examination
  • Hip Dysplasia
  • Kidney Disease
