Collie Versus Irish Terrier: Introduction

Are you thinking of getting a new pet dog, and you have narrowed down your choices to the Collie and the Irish Terrier? Well, you have come to the right place. Because in this article, we will provide you with a detailed comparison of these two dog breeds to help you decide which of the Collie and the Irish Terrier better suits you.

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

Furthermore, we will let you know which one of the Collie 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 Collie 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 Collie and the Irish Terrier.

Our only goal here is to help you make a well-thought-out decision on your next long-term companion, be it the Collie or the Irish Terrier.

Note that the Collie breed comes in two varieties based on coat texture. There is the smooth collie and the rough collie. Read our article on rough collie versus smooth collie.

Furthermore, the border collie dog breed is very different from the collie dog breed. Learn about the differences between these two dog breeds in our border collie versus collie article.

See this article that compares the Border Collie to the Irish Terrier.

Finally, just like the collie, the border collie also comes in two varieties. There is the rough border collie and the smooth border collie. To learn about the differences and similarities between them, check out our article on rough-coat border collie versus smooth-coat border collie.

Collie versus Irish Terrier

Collie versus Irish Terrier: Overview

Both the Collie and the Irish Terrier are similar in size. The Collie and the Irish Terrier are both medium-sized dogs.

Furthermore, the Collie belongs to the Herding Dogs group. Herding Dogs were bred for moving livestock, including sheep, cattle, and even reindeer. Herding dogs work closely with their human shepherds, and their natural intelligence and responsiveness make them highly trainable. They have high levels of energy, which needs to be channeled properly to prevent destructive behavior. Herding breeds are protective of their people and property and make excellent watchdogs. Their intelligence, agility, and activity level make them well suited to dog sports.

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.

Collie versus Irish Terrier: Comparison Table

The table below compares the Collie 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 Collie and the Irish Terrier

    Next, we added the scores of the factors that can be added together for the Collie 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 Collie is 83 out of 125 while the Better-Pet score for the Irish Terrier is 78 out of 125.

    Based on their Better-Pet scores, the Collie is a better pet than the Irish Terrier. So, you should get a Collie!

    The Collie has a better temperament than the Irish Terrier.

    This is because the temperament score for the Collie is 80.8 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 80.8 percent, the Collie 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 Collie and the Irish Terrier by measuring the temperaments of 896 Collies and 10 Irish Terriers.

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

    Collie Irish Terrier
    Intelligence Rank 16 out of 130 dog breeds 53 out of 130 dog breeds
    Trainability Tend To Learn New Commands After 5 To 15 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 Collie has an obedience intelligence rank of 16 out of 130 dog breeds. The Collie belongs to the `Excellent Working Dogs` category. This means that Collies tend to learn new commands after 5 to 15 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 Collie 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 Collie 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 Collie and the Irish Terrier over the years.

    Based on the AKC popularity data over the years, the Collie is more popular with dog owners than the Irish Terrier. This is because, over the years, the average popularity of the Collie is 37 out of about 200 dog breeds while the average popularity of the Irish Terrier is 118 out of about 200 dog breeds.
