Breed overview

A wolfdog is a canine hybrid produced by the mating of a domestic dog (Canis familiaris) with a wolf; this can be a gray wolf (Canis lupus), an eastern wolf (Canis lycaon), a red wolf (Canis rufus), or an Ethiopian wolf (Canis simensis). They can occur through admixture in the wild or through intentional breeding by humans.

Breed facts

  • There is evidence of widespread gene-flow from dogs into wolf populations, and very few deliberate crossings of wolves with dogs, such as the Saarloos Wolfdog.
  • Ancient DNA shows that dogs from Europe over 5,000 years ago also show little evidence of interbreeding with wild canids.
  • A wolfdog is a canine hybrid produced by the mating of a domestic dog (Canis familiaris) with a wolf; this can be a gray wolf (Canis lupus), an eastern wolf (Canis lycaon), a red wolf (Canis rufus), or an Ethiopian wolf (Canis simensis).
  • Admixture between domestic dogs and other subspecies of gray wolves are the most common wolfdogs since dogs and gray wolves are considered the same species, are genetically very close and have shared vast portions of their ranges for millennia.
  • At the same time, wolfdogs are also often bred in captivity for various purposes.

Size and appearance

The physical characteristics of an animal created by breeding a wolf to a dog are not predictable, similar to that of mixed-breed dogs. In many cases the resulting adult wolfdog may be larger than either of its parents due to the genetic phenomenon of heterosis (commonly known as hybrid vigor). Breeding experiments in Germany with poodles and wolves, and later on with the resulting wolfdogs showed unrestricted fertility, mating via free choice and no significant problems of communication (even after a few generations). However, the offspring of poodles with either coyotes and jackals, all showed a decrease in fertility, significant communication problems, and an increase of genetic diseases after three generations of interbreeding between the hybrids. The researchers therefore concluded that domestic dogs and wolves are the same species.

Personality and behavior

Wolfdogs are a mixture of genetic traits, which results in less predictable behavior patterns compared to either the wolf or dog. The adult behavior of wolfdog pups also cannot be predicted with comparable certainty to dog pups, even in third-generation pups produced by wolfdog mating with dogs or from the behavior of the parent animals. Thus, though the behavior of a single individual wolfdog may be predictable, the behavior of the type as a whole is not. Due to the variability inherent to their admixture, whether a wolf-dog cross should be considered more dangerous than a dog depends on behavior specific to the individual alone rather than to wolfdogs as a group.

Exercise and activities

Care planning: build a weekly routine with walks, play and time to explore. Enter the minutes and sessions that work for your dog, then compare the weekly total with your available time. Keep notes about the activities your dog enjoys and adjust the routine together.

Training and enrichment

Care planning: choose one everyday skill to practice and keep a record of each session. Note the cue, the reward your dog enjoys and what went well. Rotate familiar games and new activities, and use your notes to choose the next small step.

Coat and grooming

Care planning: use the coat details above to discuss a grooming routine with your groomer. Record brushing sessions, baths and appointments in the app. Add the tools you use and your preferred schedule so the whole household can follow the same routine.

Health and lifespan

Care planning: keep your dog's veterinary records, health-check dates and agreed care plan together. Add reminders for appointments and record changes you want to discuss at the next visit. Use the linked breed organizations and original references to explore their current health resources.

Living with this breed

Care planning: compare this profile's adult dimensions, coat care and available activity information with your household's routine. Make a shortlist, plan who will handle daily care and save the questions you want to ask a breed club, rescue or breeder.

Breed history

Whole genome sequencing has been used to study gene flow between wild and domestic species. There is evidence of widespread gene-flow from dogs into wolf populations, and very few deliberate crossings of wolves with dogs, such as the Saarloos Wolfdog. However, the global dog population forms a genetic cluster with little evidence for gene flow from wolves into dogs. Ancient DNA shows that dogs from Europe over 5,000 years ago also show little evidence of interbreeding with wild canids.
