The Shiba Inu, Chow Chow, and Akita Inu are often cited as the most genetically close to ancient wolves, while breeds like the Alaskan Malamute, Siberian Husky, and Samoyed also share significant wolf DNA, especially in the Nordic spitz group, with breeds like the Czechoslovakian Wolfdog and Saarloos Wolfdog being direct wolf-dog crosses. These ancient breeds diverged early from the wolf lineage, retaining more primitive traits, though wolf-dog hybrids have more recent wolf ancestry.
All dogs are close relatives of wolves—after all, domestic dogs (Canis lupus familiaris) descend from gray wolves (C. lupus). Yet, several breeds, including the Shiba Inu, Akita, Alaskan Malamute, Siberian Husky, and Chow Chow, remain genetically closer to wolves than others.
Samoyed
As one of the most genetically similar breeds to wolves, the Samoyed originated in Northern Siberia and worked similar jobs as Finnish Lapphunds. They commonly herded reindeer and hauled sleds for the Samoyed people and were often treated as part of the family.
The Shih Tzu shares more DNA with wolves than most other breeds. The only breed group with more shared wolf DNA is the Nordic spitz group (Huskies, Samoyeds, and Malamutes). The breed almost went extinct in the early 1900s. All Shih Tzus around today are descendants of a group of 13 Shih Tzus and 1 Pekingese.
It is known as the "wolf killer". The Karakachan dog was also later used in Bulgaria as a border army watchdog. The breed was almost extinguished, and was only preserved through the fierce protection and dedication of the Bulgarian shepherds in the mountain regions.
A huge majority of the livestock guardian breeds like Kangals, working bred Tibetan Mastiffs, Central Asian Shepherd Dogs, etc. would be more than capable as protection, often specifically against wolves, is what they are bred and still used for.
The "heartbreak breed" refers primarily to the Great Dane, nicknamed this due to their affectionate nature combined with a relatively short lifespan (around 7-10 years) and susceptibility to serious heart conditions like dilated cardiomyopathy (DCM), making losing them particularly difficult for their devoted owners. Other giant breeds like Irish Wolfhounds, Bernese Mountain Dogs, and Saint Bernards also face significant health challenges, including cancer and heart disease, often earning them similar sentiments from owners.
An hour for a dog feels much longer than an hour for a human because dogs perceive time more slowly due to their faster metabolism and heightened awareness of routines, so a 10-minute wait can feel like 70 minutes to them, and your hour-long absence feels like an eternity, though they don't grasp clock time but rather the intervals between events like meals, walks, and your return.
But for a clear understanding of how closely they are related, scientists compare their DNA, an essential molecule that's the instruction manual for building each species. Humans and chimps share a surprising 98.8 percent of their DNA.
The history of the Shih Tzu is a little mysterious but DNA analysis confirms that the ancestors of today's Shih Tzu breed are one of the most ancient dog breeds. It is believed the Shih Tzu's close relatives are the Tibetan Spaniels and Pekingnese of Tibet.
Huskies Are Not Wolves
Despite the similar looks, the Siberian husky is not a wolf; they are separate and distinct species. The husky a type of domesticated dog, or Canis lupus familiaris, while wolves are Canis lupus.
Wolves and wolf-dogs are notoriously difficult to train. They are incredibly independent animals that are well-adapted to life in the wild. Wolves will not respond to normal training methods and wolf-dogs are extremely unpredictable.
A 2016 meta-analysis of 25 genetics studies from 1995 to 2013 found that the northeastern coywolf is 60% western coyote, 30% eastern wolf, and 10% domestic dog. However, this hybrid canid is only now coming into contact with the southern wave of coyote migration into the southern United States.
Dogs and wolves can indeed interbreed, producing hybrids known as wolfdogs. These offspring are viable and fertile – and can go on to reproduce themselves.
The 7 Dog Breeds That Look Like Coyotes
💡 Chimpanzees share around 98-99% of their DNA with humans, making them our closest relatives in the animal kingdom! At the Center for Great Apes, our chimpanzee residents amaze us every day with their intelligence, curiosity, and playful personalities.
There have been no scientifically verified specimens of a human–chimpanzee hybrid, but there have been substantiated reports of unsuccessful attempts to create one in the Soviet Union in the 1920s, and various unsubstantiated reports on similar attempts during the second half of the 20th century.
Humans are classified in the sub-group of primates known as the Great Apes. Humans are primates, and are classified along with all other apes in a primate sub-group known as the hominoids (Superfamily Hominoidea). This ape group can be further subdivided into the Great Apes and Lesser Apes.
The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, outlining three phases: 3 Days (decompression, feeling overwhelmed/scared), 3 Weeks (starting to settle in, learning routine, personality emerges), and 3 Months (feeling secure, bonded, and truly at home). It helps new owners manage expectations and be patient as their rescue dog transitions, emphasizing calm energy, routine, and space in the early days to build trust.
Fortunately for us, dogs do not understand they are being put to sleep. They may behave differently at this time generally because they feed off the emotions of their closest humans, who are understandably destraught. Plus they also getting all of this extra attention so they probably wonder what is going on!
How do they do this? It's biological. All animals have circadian rhythms - physical, mental, and behavioral changes that follow a 24-hour cycle, responding to light and darkness in the environment. They may also be affected by factors like temperature and social cues.
Dog Breeds Most Likely to Bite
The "10 10 10 rule" for dogs refers to two main concepts: a potty training method for puppies (10 mins outside, 10 ft space, 10 mins supervision/reward) and the 80/10/10 guideline for raw feeding (80% muscle meat, 10% bone, 10% organ), both offering structure for training or diet. Another interpretation is the 10% rule for treats, limiting them to 10% of daily calories to maintain a balanced diet, ensuring most nutrition comes from complete dog food.
The only breed of dog mentioned by name in the Bible is the greyhound (Proverbs 30:29-31, King James Version): "There be three things which do well, yea, Which are comely in going; A lion, which is strongest among beasts and Turneth not away from any; A greyhound; A he-goat also."
