Chihuahua versus Boston Terrier: Overview

A very important difference between the Chihuahua and the Boston Terrier is the size difference between the two dog breeds. The Chihuahua is a tiny-sized dog while the Boston Terrier is a small-sized dog.

Furthermore, both the Chihuahua and the Boston Terrier are Companion Dogs. This means both the Chihuahua and the Boston Terrier 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.

Chihuahua versus Boston Terrier: Comparison Table

The table below compares the Chihuahua to the Boston Terrier 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 Chihuahua and the Boston Terrier

    Next, we added the scores of the factors that can be added together for the Chihuahua in the table (that is, `Ease of Grooming` score + `General Health` score + `Calmness` score + …etc) and we compared it to the corresponding total score for the Boston Terrier. 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.

    The Better-Pet score for the Chihuahua is 84 out of 125 while the Better-Pet score for the Boston Terrier is 87 out of 125.

    Despite the higher Better-Pet score of the Boston Terrier, we still believe that the Chihuahua is a better pet than the Boston Terrier.

    This is because Chihuahuas are much cuter but you cannot put a score on cuteness. If you could put a score on cuteness, then the Chihuahua will come out on top.

    Also, we are biased in favor of the Chihuahua :-). We are for the Chihuahua. So get a Chihuahua!

    Note that a lot of factors determine how much you can expect to pay for the Chihuahua puppy or the Boston Terrier 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 Chihuahua versus the Intelligence of the Boston Terrier

    `
    Chihuahua Boston Terrier
    Intelligence Rank 67 out of 130 dog breeds 54 out of 130 dog breeds
    Trainability Tend To Learn New Commands After 40 To 80 Repetitions! Tend To Learn New Commands After 25 To 40 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 Chihuahua has an obedience intelligence rank of 67 out of 130 dog breeds. The Chihuahua belongs to the `Fair Working/Obedience Intelligence Dogs` category. This means that Chihuahuas tend to learn new commands after 40 to 80 repetitions!.

    The Boston Terrier has an obedience intelligence rank of 54 out of 130 dog breeds. The Boston Terrier belongs to the `Average Working/Obedience Intelligence Dogs` category. This means that Boston Terriers tend to learn new commands after 25 to 40 repetitions.

    The Boston Terrier is more intelligent than the Chihuahua.

    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.
