Collie Versus Mastiff: Introduction
Are you thinking of getting a new pet dog, and you have narrowed down your choices to the Collie and the Mastiff? 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 Mastiff 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 Mastiff.
Furthermore, we will let you know which one of the Collie and the Mastiff 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 Mastiff. 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 Mastiff.
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 Mastiff.
Collie versus Mastiff: Overview
A very important difference between the Collie and the Mastiff is the size difference between the two dog breeds. The Collie is a medium-sized dog while the Mastiff is a giant-sized dog.
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 Mastiff 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.
Collie versus Mastiff: Comparison Table
The table below compares the Collie to the Mastiff 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 Mastiff
| Factor | Collie | Mastiff |
|---|---|---|
| Does NOT Drool | 5/5 | 1/5 |
| Tendency NOT to Wander | 5/5 | 5/5 |

| Common Health Problems and Recommended Health Tests |
|
|
| Popularity out of 200 Dog Breeds | 37 | 28 |
| Intelligence Rank (out of 130 Dog Breeds) | 16 | 72 |
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 Mastiff. 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 Mastiff is 72 out of 125.
Based on their Better-Pet scores, the Collie is a better pet than the Mastiff. So, you should get the Collie!
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 Collie and the Mastiff so that you can make your own well-informed decision on which pet to get.
The Most Remarkable Differences Between the Collie and the Mastiff
Below is a list of where the Collie and the Mastiff are most different:
The Similarities Between the Collie and the Mastiff
The Collie and the Mastiff are very similar in certain aspects. Below is the list of where the Collie and the Mastiff are most similar:
Size (Weight and Height) of Collie versus Mastiff
Now, let us discuss the difference in size between the Collie and the Mastiff.
Collies weigh 50 to 70 pounds when fully grown. Collies are 22 to 26 inches all at the shoulder when fully grown.
On the other hand, Mastiffs weigh 130 to 220 pounds when fully grown. Mastiffs are 27 to 32 inches tall at the shoulder when fully grown.
Lifespan of Collie versus Mastiff
The lifespan of Collies is between 10 to 14 years. The average lifespan of Collies is 12.0 years.
The lifespan of Mastiffs is between 6 to 10 years. The average lifespan of Mastiffs is 8.0 years.
Collies live longer than Mastiffs.
Temperament of the Mastiff Versus the Collie
The Mastiff has a better temperament than the Collie.
This is because the temperament score for the Mastiff is 100.0 percent while the temperament score for the Collie is 80.8 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 100.0 percent, the Mastiff has an above-average temperament compared to other dog breeds.
The ATTS obtained the temperament scores of the Collie and the Mastiff by measuring the temperaments of 896 Collies and 8 Mastiffs.
Price of Collie versus Price of Mastiff
The average price of the Collie puppy is $1480. The price of the Collie typically ranges from $1000 – $1800. However, the price of a Collie can be as low as $300 and as high as $15000. We obtained this price information by reviewing the prices of 356 Collie puppies listed for sale from various sources.
The average price of the Mastiff puppy is $1740. The price of the Mastiff typically ranges from $1100 – $2200. However, the price of the Mastiff can be as low as $200 and as high as $4600. We obtained this price information by collecting and reviewing the prices of 248 Mastiff puppies listed for sale from various sources.
The Mastiff is more expensive than the Collie.
| Collie | Mastiff | |
|---|---|---|
| Average Price | $1480 | $1740 |
| Price Range | $1000 to $1800 | $1100 to $2200 |
The charts below show the price distribution for the Collie and Mastiff. For different price points, the charts show how many Collie puppies or how many Mastiff puppies are listed for sale at those price points.
A breakdown of the prices of Collies. The typical price range is shaded Green.
A breakdown of the prices of Mastiffs
Note that a lot of factors determine how much you can expect to pay for the Collie puppy or the Mastiff 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 Mastiff
| Collie | Mastiff | |
|---|---|---|
| Intelligence Rank | 16 out of 130 dog breeds | 72 out of 130 dog breeds |
| Trainability | Tend To Learn New Commands After 5 To 15 Repetitions | Tend To Learn New Commands After 80 To 100 Repetitions Or More! |
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:
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 Mastiff has an obedience intelligence rank of 72 out of 130 dog breeds. The Mastiff belongs to the `Lowest Degree of Working/Obedience Intelligence Dogs` category. This means that Mastiffs tend to learn new commands after 80 to 100 repetitions or more!.
The Collie is more intelligent than the Mastiff.
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 Mastiff
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 Mastiff over the years.
Based on the AKC popularity data over the years, the Mastiff is more popular with dog owners than the Collie. This is because, over the years, the average popularity of the Mastiff is 28 out of about 200 dog breeds while the average popularity of the Collie is 37 out of about 200 dog breeds.
Popularity of Collie
Popularity of Mastiff
| Year | Collie Popularity Rank | Mastiff Popularity Rank |

Health Problems of Collie versus Health Problems of Mastiff
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 Collie and the Mastiff 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 Mastiff is prone to more genetic health problems than the Collie.
This is because the OFA recommends more screening health tests for the Mastiff than for the Collie.
4 health tests are recommended for Collie while 7 tests are recommended for the Mastiff.
Below is a detailed discussion of health problems in Collies and in Mastiffs.
Collie Health Problems
Collies are genetically prone to certain health problems. However, breeders can reduce the chances of producing Collie 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 Collie puppy that will grow up to be healthy, make sure that your Collie 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 Collies for:
You can find out more about OFA`s recommended tests for Collies here.
Mastiff Health Problems
Mastiffs are genetically prone to certain health problems. However, breeders can reduce the chances of producing Mastiff 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 Mastiff puppy that will grow up to be healthy, make sure that your Mastiff 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 Mastiffs for:

More Discussions on Health Problems in Collies and Mastiffs
Based on our analysis of data from the Orthopedic Foundation for Animals, of all known genetic health problems in dogs, the health problem that is most commonly seen in the Collie Breed is Collie Eye Anomaly problems.
This is because the Collie ranks 1 out of 7 dog breeds for Collie Eye Anomaly problems. In fact, in a health test conducted on 114 Collies, 16 of them had Collie Eye Anomaly problems.
The genetic diseases that were found to commonly occur in Collies, and how common these diseases are in Collies relative to other dog breeds, are given below:
Based on our analysis of data from the Orthopedic Foundation for Animals, of all known genetic health problems in dogs, the health problem that is most commonly seen in the Mastiff Breed is Canine Multifocal Retinopathy problems.
This is because the Mastiff ranks 3 out of 6 dog breeds for Canine Multifocal Retinopathy problems. In fact, in a health test conducted on 891 Mastiffs, 14 of them had Canine Multifocal Retinopathy problems.
The genetic diseases that were found to commonly occur in Mastiffs, and how common these diseases are in Mastiffs relative to other dog breeds, are given below:
The table below lists the common health problems in Collie and in Mastiff and the rank (prevalence), compared to other dogs, of these health problems in the Collie and the Mastiff:
| Disease | Collie Rank | Mastiff Rank |
|---|---|---|
| Collie Eye Anomaly problems | 1 out of 7 dog breeds | Not Common |
| Eyes problems | 1 out of 182 dog breeds | 43 out of 182 dog breeds |
| Multiple Drug Resistance (Mdr1) problems | 1 out of 7 dog breeds | Not Common |
| Dentition Database problems | 13 out of 49 dog breeds | Not Common |
| Degenerative Myelopathy problems | 16 out of 70 dog breeds | 49 out of 70 dog breeds |
| Thyroid problems | 65 out of 115 dog breeds | 72 out of 115 dog breeds |
| Elbow problems | 107 out of 144 dog breeds | 26 out of 144 dog breeds |
| Hips problems | 182 out of 198 dog breeds | 39 out of 198 dog breeds |
| Canine Multifocal Retinopathy problems | Not Common | 3 out of 6 dog breeds |
| Cystinuria problems | Not Common | 3 out of 6 dog breeds |
| Shoulder problems | Not Common | 9 out of 22 dog breeds |
| Progressive Retinal Atrophy problems | Not Common | 12 out of 32 dog breeds |
| Advanced Cardiac problems | Not Common | 39 out of 71 dog breeds |
| Congenital Cardiac problems | Not Common | 53 out of 159 dog breeds |
| Patella problems | Not Common | 131 out of 145 dog breeds |
*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.
