Most Loyal Dog Breeds: What the Research Says

Is there a ranking of the most loyal dog breeds?

No. Unlike intelligence, where psychologist Stanley Coren at least surveyed obedience judges (see our smartest dog breeds guide), there is no published ranking of breeds by loyalty. Loyalty is hard to define and harder to measure. Is it staying close, coming when called, guarding the house, or pining when you leave? Different lists mean different things, and most simply repeat each other.

What researchers do measure is attachment: whether a dog treats a particular person as a source of safety and comfort. That turns out to be the more useful question, and its answer is encouraging for anyone thinking about adopting.

What does research say about dog loyalty?

Dogs attach to their owners much as children attach to parents

In a 1998 study in the Journal of Comparative Psychology, József Topál and colleagues at Eötvös Loránd University put 51 owner and dog pairs through a version of the Strange Situation Test, a procedure developed to study how infants attach to their mothers. In the test, a dog meets a stranger in an unfamiliar room and is briefly separated from and reunited with its owner. Adult dogs showed patterns of attachment behaviour toward their owners, and the researchers compared the bond to child and parent attachment.

Two findings matter for choosing a dog. There was a lot of variation between individual dogs. And the researchers found no effect of gender, age, living conditions or breed on most of the behaviours they measured. On this evidence, loyalty in the attachment sense is a dog trait, not a breed trait.

Breed predicts less than you might think

A much larger 2022 study in Science surveyed the owners of 18,385 dogs and genotyped 2,155 of them. Breed explained just 9% of the variation in behaviour between individual dogs. One of its findings helps untangle what people mean by a loyal dog. In owners' survey answers on sociability with people, Labradors, Golden Retrievers and Siberian Huskies were more likely than an average dog to score in the top quarter, and German Shepherd Dogs less likely. The study also found herding breeds, as a group, were more aloof and more responsive to direction.

So “loves everyone” and “devoted to its own people” are two different things. A friendly retriever greets the plumber like an old friend; a reserved herding dog may stick to its family and ignore the plumber. Both can be deeply attached to the people they live with.

Which dog breeds do the standards describe as loyal?

A breed standard sets out the ideal temperament for a breed. These are the Dogs Australia standards that describe loyalty, devotion or faithfulness in so many words, checked 10 November 2026.

A breed standard describes the ideal dog of a breed, not a promise about any one dog. The order is not a ranking.

Notice where the word loyal turns up. The Kelpie, Cattle Dog and Border Collie standards tie loyalty to work: “devotion to duty”, guarding the stockman, being kindly towards stock. The Rottweiler and Dobermann pair it with obedience. The Boxer and the Labrador describe a family companion. All of these are dogs bred to work closely with people, which is much of what loyalty means in practice.

Which breeds are one-person dogs?

“One-person dog” usually describes a dog that is warm with its own people and cool with strangers. Several standards describe that reserve:

• Shetland Sheepdog: “affectionate and responsive to his owner, reserved towards strangers” (standard).
• Australian Cattle Dog: “naturally suspicious of strangers, must be amenable to handling” (standard).
• Chow Chow: “loyal yet aloof” (standard).
• Akita: “dignified, courageous, aloof” (standard).
• Basenji: “can be aloof with strangers” (standard).

None of these standards says the dog bonds with only one member of a family. In most homes a dog attaches to the people who feed, walk and play with it, and it can attach to more than one. If you want a dog that is close to one person in particular, that person needs to be the one doing the daily care and training.

What is the downside of a very loyal dog?

The traits people love in a devoted dog have two common costs.

It may not cope with being left alone

The RSPCA Knowledgebase explains that many dogs become anxious when separated from the person or family group they are attached to. Signs include toileting in the house, destructiveness, excessive barking, digging, pacing and trying to escape. It also says separation anxiety is a mental health issue that needs veterinary treatment, so see your vet if you suspect it.

Australian research links this directly to attachment. A University of Sydney study of 513 Golden Retrievers and Labradors, published in 2018, notes that separation-related behaviours are reported in an estimated 14 to 29% of companion dogs. In its own sample, those behaviours were most strongly correlated with a group of traits that included attachment and attention-seeking behaviour. A dog that follows you from room to room is lovely, until you need to go to work.

The RSPCA's advice is to teach the dog to be calm and relaxed when its person is away: keep departures and returns low-key, reward calm behaviour, build time alone gradually, and give plenty of physical and mental exercise. Start in the first weeks, not after a problem appears.

It may guard what it loves

Devotion and protectiveness often travel together. The Australian Cattle Dog standard says its loyalty and protective instincts make it a self-appointed guardian, and several of the breeds above were developed for guarding. A protective dog needs early, careful socialisation so visitors, tradespeople and children's friends are not treated as threats. Our guard dogs guide explains the difference between a watchdog and a guardian breed and each state's restricted breed and dangerous dog rules.

Will an adopted dog be loyal to you?

Yes, and the research here is some of the most encouraging there is for adopters. In a 2001 study, Márta Gácsi and colleagues worked with 60 adult dogs living in two Hungarian shelters, where they had very little contact with people. Forty of the dogs were handled by a new person for three 10-minute sessions; the other 20 were not. In a Strange Situation Test, the handled dogs sought contact with their handler, stayed with them rather than standing at the door, and paid less attention to a stranger. The researchers concluded that the handled dogs' response met the criteria for attachment, and that even adult dogs can form attachments quickly.

They also pointed out the myth this challenges: the belief that a dog must be raised from a young puppy to bond with you, which they said puts people off adopting from shelters.

One honest caution

The same University of Sydney retriever study found separation-related behaviour scores were higher in dogs acquired from pet shops, shelters and rescue organisations than in those from breeders or service organisations. A survey like that cannot say why, and it covered two breeds only. The practical lesson is simple: ask how a rescue dog copes when left alone, and plan its first weeks around building that skill.

Questions to ask the foster carer

• How does the dog behave when left alone, and for how long has it been left?
• Does it follow people from room to room, or settle on its own?
• How does it react to visitors and strangers on walks?
• Does it guard food, toys, its bed or a particular person?
• How quickly did it warm up to the carer when it first arrived?

The RSPCA Knowledgebase recommends starting your search with shelters and rescues. Give a new dog a few quiet days to decompress before you expect much; our free dog training plan starts there.

How do you build loyalty in any dog?

Through the same things that build any relationship: time, predictability and good experiences. The RSPCA says training builds trust and clear communication between caregiver and dog, and that positive reinforcement training enhances the relationship between dog and handler. It also warns that physical punishment and aversive equipment can harm the dog's relationship with people.

• Be the source of good things: meals, walks, play and training rewards.
• Keep a routine so the dog learns what each day looks like.
• Train with rewards for a few minutes most days. Our easiest dogs to train guide and the free dog training course are good starting points.
• Teach time alone early, so devotion never turns into distress.
