Cavalier King Charles Spaniel versus Bullmastiff: Overview

A very important difference between the Cavalier King Charles Spaniel and the Bullmastiff is the size difference between the two dog breeds. The Cavalier King Charles Spaniel is a small-sized dog while the Bullmastiff is a giant-sized dog.

Furthermore, the Cavalier King Charles Spaniel belongs to the Companion Dogs group. Companion Dogs were bred to be companions for humans. Their main goal in life is to be with people, and they will be very sad if left to themselves for long hours day after day.

On the other hand, the Bullmastiff belongs to the Working Dogs group. Working Dogs were developed to assist humans in some capacity – including pulling sleds and carts, guarding flocks, guarding homes, and protecting their families. Breeds in the Working Group are known for their imposing stature, strength, intelligence, and fearless. 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.

Cavalier King Charles Spaniel versus Bullmastiff: Comparison Table

The table below compares the Cavalier King Charles Spaniel to the Bullmastiff 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 Cavalier King Charles Spaniel and the Bullmastiff

    Note that a lot of factors determine how much you can expect to pay for the Cavalier King Charles Spaniel puppy or the Bullmastiff 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.

    The Intelligence of the Cavalier King Charles Spaniel versus the Intelligence of the Bullmastiff

    Cavalier King Charles Spaniel Bullmastiff
    Intelligence Rank 44 out of 130 dog breeds 69 out of 130 dog breeds
    Trainability Tend To Learn New Commands After 25 To 40 Repetitions Tend To Learn New Commands After 40 To 80 Repetitions!

    Professor Stanley Coren, the famous psychology/neuropsychological professor and, dog lover/trainer measured and ranked the intelligence of about 130 different dog breeds.

    According to Prof. Stanley Coren, the total intelligence that a dog demonstrates is the addition of three types of intelligence. These intelligence types are:

  • Instinctive Intelligence: This is the natural intelligence a dog has because of what the dog was bred for. This type of intelligence comes from instinct. For example, dog breeds that were bred for guarding will have high `guarding` instinctive intelligence, while dog breeds that were bred for hunting will what high `hunting` instinctive intelligence. However, you cannot compare the intelligence of dog breeds based on instinctive intelligence because such a comparison will not make sense.
  • Adaptive Intelligence (learning and problem-solving ability): This indicates what a dog can learn to do for himself or herself. It includes learning and benefiting from experience with his environment, solving new problems, and so forth. Adaptive intelligence is specific to each dog, and not breed specific. Thus, two dogs can have remarkably different levels of adaptive intelligence even if they are of the same breed.
  • Working/Obedience Intelligence: This intelligence is the closest to what we might call school-learning ability and it is based upon what the dog can learn to do when instructed by humans. Importantly, different dog breeds have different learning abilities. Also, science has shown that some dog breeds can learn faster than some other breeds. This means certain dog breeds tend to have higher working/obedience intelligence than some other breeds. Dogs with high Working/Obedience Intelligence are smart and easy to train.

  • Prof. Coren showed that the Working/Obedience Intelligence of different dog breeds can be measured reliably. Thus, he was able to rank different dog breeds based on their Working/Obedience Intelligence.

    This is important because according to Prof. Coren, 51 percent of a dog`s intelligence comes from its genes while 49 percent of a dog`s intelligence comes from the dog`s environmental circumstances.

    To rank the intelligence of dog breeds, Prof. Coren employed the help of 208 dog obedience judges in North America to fill out a detailed survey on dog obedience. This number represented more than half of all of these judges in North America at the time. He also employed 63 veterinarians and 14 guard dog experts to collect data on the personality of different dog breeds.

    Prof. Coren found that the Cavalier King Charles Spaniel has an obedience intelligence rank of 44 out of 130 dog breeds. The Cavalier King Charles Spaniel belongs to the `Average Working/Obedience Intelligence Dogs` category. This means that Cavalier King Charles Spaniels tend to learn new commands after 25 to 40 repetitions.

    The Bullmastiff has an obedience intelligence rank of 69 out of 130 dog breeds. The Bullmastiff belongs to the `Fair Working/Obedience Intelligence Dogs` category. This means that Bullmastiffs tend to learn new commands after 40 to 80 repetitions!.

    The Cavalier King Charles Spaniel is more intelligent than the Bullmastiff.

    However, Prof. Coren noted that a dog should not be judged based on its intelligence alone, that other factors such as sociability, adorability, and compatibility with the owner are other very important factors that new dog owners need to consider when deciding on a new dog.

    The Popularity of Cavalier King Charles Spaniel versus Popularity of Bullmastiff

    Every year, the American Kennel Club (AKC) publishes information on how popular a dog breed is in that particular year. The AKC gets the popularity information of a breed from how many dogs of that breed the owners register with the AKC every year. The AKC collects this data for about 200 dog breeds. The AKC collects this data for purebred dogs only(no mixed or hybrid dogs).

    The graphs and the table below show the popularity of the Cavalier King Charles Spaniel and the Bullmastiff over the years.

    Based on the AKC popularity data over the years, the Cavalier King Charles Spaniel is more popular with dog owners than the Bullmastiff.

    Health Problems of Cavalier King Charles Spaniel versus Health Problems of Bullmastiff

    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 Cavalier King Charles Spaniel and the Bullmastiff 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 Bullmastiff is prone to more genetic health problems than the Cavalier King Charles Spaniel.

    This is because the OFA recommends more screening health tests for the Bullmastiff than for the Cavalier King Charles Spaniel.

    4 health tests are recommended for Cavalier King Charles Spaniel while 6 tests are recommended for the Bullmastiff.

    Below is a detailed discussion of health problems in Cavalier King Charles Spaniels and in Bullmastiffs.

    Cavalier King Charles Spaniel Health Problems

    Cavalier King Charles Spaniels are genetically prone to certain health problems. However, breeders can reduce the chances of producing Cavalier King Charles Spaniel 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 Cavalier King Charles Spaniel puppy that will grow up to be healthy, make sure that your Cavalier King Charles Spaniel 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 Cavalier King Charles Spaniels for:

  • Cardiac Evaluation
  • Eye Examination;
  • Hip Dysplasia

    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

    *To learn more about each of these diseases, go to OFA.org and search for the disease.

    Again, most of these health problems can be prevented through health screening. Responsible breeders screen male and female dog parents for genetic problems. These breeders will only breed dogs that are free of genetic defects. That way, there is little or no chance that their puppies will grow up to have genetic health problems. Always ask a breeder for the list of health tests the breeder screens their dogs for before buying a puppy from such a breeder.
