We will provide you a detailed discussion and comparison of dog attributes such as intelligence, price, general health, friendliness, etc, for both the Yorkshire Terrier and the Irish Terrier.

Furthermore, we will let you know which one of the Yorkshire Terrier and the Irish Terrier is better suited for new dog owners, for owners with kids, for owners that live in apartments, for owners with dog allergies, etc.

Importantly, we did some analysis and calculation and we obtained a number that we call the Better-Pet Score™ for both the Yorkshire Terrier and for the Irish Terrier. The dog breed with the higher Better-Pet score is the `better` pet. We hope that these Better-Pet Scores will provide you with more insight into deciding which pet to get between the Yorkshire Terrier and the Irish Terrier.

Yorkshire Terrier versus Irish Terrier

Yorkshire Terrier versus Irish Terrier: Overview

A very important difference between the Yorkshire Terrier and the Irish Terrier is the size difference between the two dog breeds. The Yorkshire Terrier is a tiny-sized dog while the Irish Terrier is a medium-sized dog.

Furthermore, the Yorkshire Terrier 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 Irish Terrier belongs to the Terrier Dogs group. Terrier Dogs were originally bred to go underground to hunt rodents and other small wild animals (vermin). Terriers come in a wide range of sizes and shapes, but all terriers are energetic, highly intelligent, and territorial. Terries also have the tendency to escape. They require a securely fenced yard.

Yorkshire Terrier versus Irish Terrier: Comparison Table

The table below compares the Yorkshire Terrier to the Irish 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 Yorkshire Terrier and the Irish Terrier

    Next, we added the scores of the factors that can be added together for the Yorkshire Terrier 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 Irish 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 Yorkshire Terrier is 76 out of 125 while the Better-Pet score for the Irish Terrier is 78 out of 125.

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

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

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

    This is because the temperament score for the Yorkshire Terrier is 83.7 percent while the temperament score for the Irish Terrier is 80.0 percent, according to the American Temperament Test Society (ATTS).

    The American Temperament Test Society (ATTS) is a non-profit organization whose mission is to provide fair and objective evaluations of the temperaments of dog breeds.

    Dog breeds with low temperament scores tend to show unprovoked aggression, they easily panic without quickly recovering from the panic, and they tend to avoid people. However, dog breeds with high temperament scores are not aggressive and are not shy. Also, these dogs are generally friendly and are protective of their owners.

    The average temperament score across all dog breeds (over 250 breeds) is 83.7 percent.

    With its temperament score of 83.7 percent, the Yorkshire Terrier has a below-average temperament compared to other dog breeds.

    With its temperament score of 80.0 percent, the Irish Terrier has a below-average temperament compared to other dog breeds.

    The ATTS obtained the temperament scores of the Yorkshire Terrier and the Irish Terrier by measuring the temperaments of 43 Yorkshire Terriers and 10 Irish Terriers.

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

    `
    Yorkshire Terrier Irish Terrier
    Intelligence Rank 27 out of 130 dog breeds 53 out of 130 dog breeds
    Trainability Tend To Learn New Commands After 15 To 25 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 Yorkshire Terrier has an obedience intelligence rank of 27 out of 130 dog breeds. The Yorkshire Terrier belongs to the `Above Average Working Dogs` category. This means that Yorkshire Terriers tend to learn new commands after 15 to 25 repetitions.

    The Irish Terrier has an obedience intelligence rank of 53 out of 130 dog breeds. The Irish Terrier belongs to the `Average Working/Obedience Intelligence Dogs` category. This means that Irish Terriers tend to learn new commands after 25 to 40 repetitions.

    The Yorkshire Terrier is more intelligent than the Irish Terrier.

    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 Yorkshire Terrier versus Popularity of Irish Terrier

    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 Yorkshire Terrier and the Irish Terrier over the years.

    Based on the AKC popularity data over the years, the Yorkshire Terrier is more popular with dog owners than the Irish Terrier. This is because, over the years, the average popularity of the Yorkshire Terrier is 9 out of about 200 dog breeds while the average popularity of the Irish Terrier is 118 out of about 200 dog breeds.
