Wolf-Dog Hybrids

Wolves and dogs can interbreed and produce offspring. These offspring are usually fertile and are known as wolf hybrids. Wolves can be crossed with any breed of dog. The most common hybrids are wolf bred with malamute, husky, or German shepherd. Although wolf hybrids can occur naturally in the wild, this happens very infrequently due to the territorial nature of the wolf. Most hybrids are the result of deliberate breeding in captivity.

Wolves and dogs mature at different rates, which can make the physical development of the hybrid unpredictable. The female dog reaches sexual maturity at 6-8 months of age, and has two estrus cycles per year. The female wolf reaches sexual maturity at 2-4 years and has one estrus cycle per year, in February or March. The female hybrid can reach sexual maturity at any time between these two extremes, and can have one or two estrus cycles per year.

The male dog matures sexually around 8 months, and usually exhibits raised leg urination (RLU). The male wolf matures sexually between 2 and 3 years depending on pack status, and may or may not exhibit RLU. Male hybrids can mature anywhere between these two extremes and may or may not exhibit RLU.

Dogs readily take to training, and can be easily housebroken. Wolves do not train well and cannot be housebroken, due in part to their territorial nature and to the importance of elimination in marking their territories, as well as for other reasons. Hybrids may fall anywhere between these two extremes.

Myths Regarding Wolf Hybrids
MYTH: A wolf hybrid will make a better guard dog.
FACT: Due to the shy nature of wolves, hybrids usually make poor protection dogs. Aggressive tendencies, if any, in the hybrid may be fear induced and as such, can be unpredictable and hard to control.
MYTH: A wolf hybrid will live longer than a dog.
FACT: The life span of a wolf in captivity is 12-14 years-the same as a large dog.
MYTH: Hybrids are healthier than dogs, and are less prone to disease.
FACT: Wolves and dogs are prone to the same infectious diseases. There may be some question as to the efficacy of standard dog vaccines in wolves and some hybrids.
MYTH: Huskies and malamutes are part wolf.
FACT: Huskies and malamutes are breeds of dogs, like any other.

Wolf Content in the Hybrid

Many breeders who deal in wolf hybrids promote the 'wolf content' of the pups and even set their prices according to the 'amount of wolf blood' in the litter. This is not based on sound biology or genetics.

When one breeds a dog with a wolf, the offspring will inherit a set of genes from each parent, and are indeed 50/50 - that is, one-half dog and one-half wolf. However, when these animals are bred with other 50/50 hybrids, there is no way to calculate or manipulate which genes are passed to the offspring. As a result, these offspring may inherit a majority of dog genes from both parents and would herefore be predominantly dog - both physically and behaviorally. Or conversely, they could be predominantly wolf, or any variation or combination in between. The ideal wolf hybrid would be one that looks like a wolf and behaves like a dog, but unfortunately, many times one ends up with an animal that looks like a dog and has the obstinate nature of a wolf.

Legal Aspects of Wolf Hybrid Ownership

Laws vary from area to area. In some states, hybrids are classified as wild animals and owners are required to possess the same type of permits and caging as for a wolf. In other states, hybrids are regulated as dogs, needing only proper vaccinations and licenses.
