It comes from a dog and a wolf. Some are born in the wild. Some are born by people.

In the wild, this happens near where people live. This can happen if there are not many wolves left.

Some people breed them on purpose. They may want a dog that looks like a wolf. They may want a dog for work.

One kind is the Saarloos Wolfdog. It was made from a German Shepherd and a wolf. It was made to be a good house dog.

Another kind is the Czechoslovakian Wolfdog.

A wolfdog is a hybrid. This means it is a mix of two different types. Usually, it is a mix of a domestic dog and a wolf.

Some wolfdogs are born in the wild. This often happens near where people live. It can happen when there are not many wolves left in an area. Scientists study how genes move between dogs and wolves. This is called gene flow. One way genes move is through admixture. Admixture is when different groups mix together.

Some people make wolfdog breeds on purpose. They might want a pet that looks wild. Others want a dog for hard work. The Saarloos Wolfdog was made in 1932. A breeder mixed a German Shepherd with a wolf. He wanted a dog that was a good house pet.

The Czechoslovakian Wolfdog is another breed. It was made in the 1950s. People used it for border patrol. It is strong and can do many jobs. It can help with search and rescue.

Some wolves have black fur. This color comes from a mutation. A mutation is a small change in genes. This change first came from domestic dogs.

A wolfdog is a hybrid animal. This happens when a domestic dog mates with a wolf.

They can come from many types of wolves. This includes the gray wolf, the eastern wolf, the red wolf, or the Ethiopian wolf. Most wolfdogs are mixes of dogs and gray wolves. This is because dogs and gray wolves are very close in their genes. They have lived in the same areas for thousands of years. These mixes often happen in the wild when wolf numbers go down.

Mixing can happen in many different ways. In the wild, it often occurs near where people live. Wolves are usually aggressive toward dogs. However, a wolf might become playful if it is socially isolated. This can lead to mating between the two species. Scientists also see people making wolfdog breeds on purpose. Some people want a pet that looks exotic. Others want a dog that can do hard jobs. For example, some people breed them for military work.

Humans have been recording these mixes for a long time. The first record in Great Britain was in 1766. A male wolf mated with a dog called a Pomeranian. This resulted in nine pups. In the 1930s, Leendert Saarloos created a new breed. He crossed a male German Shepherd with a female European wolf. He wanted a hardy house dog. The Dutch Kennel Club recognized this breed in 1975.

There are several special breeds of wolfdogs today. The Czechoslovakian Wolfdog was created in the 1950s. It was made from German Shepherds and Carpathian gray wolves. It was used for border patrol in the Czech Republic and Slovakia. Today, these dogs help with search and rescue or police work.

Another breed is the Volkosob. Russian border guards wanted a dog with the strength of a wolf. They used German Shepherds and a Caspian Steppe Wolf to make it. In the United States, over 100,000 wolfdogs existed as of 1999.

Wolfdogs even change how other animals look. Scientists found that some wolves have black fur. This color comes from a mutation, which is a small change in genes. This specific change first appeared in domestic dogs. It was passed to wolves through admixture, or mixing. This mutation happened between 13,000 and 120,000 years ago. Some experts believe dogs brought this trait to the New World. This shows how much dogs and wolves are linked together.

A wolfdog is a hybrid animal produced by mating a domestic dog with a wolf.

This hybridization can involve several different wolf species. These include the gray wolf, the eastern wolf, the red wolf, or the Ethiopian wolf. Most wolfdogs are the result of mixing dogs with gray wolves. This is because dogs and gray wolves are genetically very close. They have shared vast portions of their geographic ranges for many millennia.

In the wild, this mixing often happens when wolf populations decline due to human impacts. This process is called admixture, which is the mixing of different species' genes. Admixture usually occurs near human habitations where wolf density is low and dogs are common. While wolves are typically aggressive toward dogs, a wolf may become playful or submissive if it is socially isolated. This change in behavior can lead to mating between the two species.

Scientists have used whole genome sequencing to study how genes flow between these species. Research shows widespread gene flow from dogs into wolf populations. However, there is very little evidence of gene flow from wolves into dogs. Ancient DNA shows that dogs from Europe over 5,000 years ago also had little interbreeding with wild canids. This suggests that while dogs influence wolves, the domestic dog genetic cluster remains mostly distinct.

Humans also create wolfdogs in captivity for specific purposes. Some people breed them to create exotic-looking pets. Others breed them for professional work, such as military or police duties. For example, the Czechoslovakian Wolfdog was created in the 1950s for border patrol.

It was bred from German Shepherds and Carpathian gray wolves. Today, these dogs are used for search and rescue, therapy work, and herding. Another breed, the Volkosob, was developed in the 1990s for Russian border guards. It combined the pack mentality of German Shepherds with the cold-resistance of the Caspian Steppe Wolf.

There are other recognized breeds with specific histories of intentional crossing. The Saarloos Wolfdog was created in 1932 by Dutch breeder Leendert Saarloos. He crossed a male German Shepherd with a female European wolf.

He intended to create a hardy, self-reliant companion for the home. The Dutch Kennel Club recognized the breed in 1975. Other unusual crosses include the "wolamute," which is a mix of an Alaskan Malamute and a timber wolf. Even more unusual experiments have occurred, such as crossing wolves with Poodles in Germany.

Wolfdog genetics can even change the physical appearance of wild populations. Research shows that wolves with black pelts owe their color to a specific mutation. This mutation first arose in domestic dogs. It involves a gene mutation responsible for the protein beta-defensin 3. This mutation entered the wolf population through admixture.

Experts believe this mutation occurred between 13,000 and 120,000 years ago. Some biologists suggest dogs brought this trait to the New World.

The existence of wolfdogs is a subject of significant legal and scientific debate. Many organizations, such as the Humane Society of the United States, consider wolfdogs to be wild animals. They argue that wolfdogs are unsuitable as pets. Because of this, many regions have passed breed-specific legislation. In the United States, 40 states effectively forbid the ownership or breeding of wolfdogs. In Canada, several provinces, including Alberta and Manitoba, also have strict regulations. This controversy continues as scientists study how these hybrids affect the survival of pure wolf populations.
