When a wolf and a dog breed, the offspring they produce are fertile. That means that these offspring can also breed. Dogs can also be bred with coyotes, producing a coydog.
You can, in fact, even breed dogs with other genetically-similar species, such as wolves, coyotes or dingoes, to produce what is known as a 'hybrid'.
Short answer: no, they can't. They simply don't have compatible parts. (Of course, that doesn't mean they can't be friends: witness Juniper the Fox and Moose the Dog, above). The longer answer to why dog-fox hybrids can't exist has to do with the two species having vastly different numbers of chromosomes.
Yes, wolves and domestic dogs can breed and produce fertile offspring. However, dogs have been shaped for human needs in the process of domestication, so that they are different from their wild ancestors in many characteristics.
Dingoes and domestic dogs interbreed freely with each other and therefore the term "wild dog" is often used for describing all dingoes, dingo-hybrids and other feral domestic dogs, because the borders between the three are unclear.
But creating hybrids of animals that are very genetically distinct from each other—such as a dog and a cat—is scientifically impossible, as is one species giving birth to an entirely different one.
They are different species and can not interbreed. Hyenas are more closely related to cats than canines despite their appearance.
A jackal–dog hybrid is a canid hybrid resulting from a mating between a domestic dog and a golden jackal. Such crossbreeding has occurred numerous times in captivity and was first confirmed to occasionally happen in the wild in Croatia in 2015.
Coyotes and dogs are related, and they are biologically capable of producing hybrid litters. Coydogs have been raised in captivity. Genetic surveys of wild coyotes have rarely documented evidence of dogs in the genetic makeup of coyotes, despite domestic dogs and coyotes sharing the continent for the past 9,000 years.
A calf with a perfect dog's head was born yesterday at the dairy farm of A. P. Reed on the Fairview Road, although, it died within a few minutes after birth. The calf was dropped by a fine Holstein cow which the owner had recently imported from the north and weighed 100 pounds when found.
A dog has 39 pairs of chromosomes and is a canis; kangaroos are from in a class called marsupial and they have only 22 pairs of chromosomes - they cannot breed.
The wolf (including the dingo and domestic dog), coyote, and jackal, all have 78 chromosomes arranged in 39 pairs. This allows them to hybridise freely (barring size or behavioural constraints) and produce fertile offspring. The wolf, coyote, and golden jackal diverged around 3 to 4 million years ago.
Fact #1: Unlike domestic dogs, wild dogs have long legs, four toes on their front feet and large, rounded ears. Though both species descended from wolves, they are unable to interbreed, and wild dogs can't be domesticated.
Although a wolf can be bred with a dog (i.e. Wolf-Dog hybrids), a fox cannot be bred with a wolf. Wolves, coyotes, dogs, dingos, and jackals all have 78 chromosomes in 39 pairs. They all share the same genus.
The hyena conceives by a wolf and brings forth Onolysum. Evidence for the occurrence of hyena hybrids is sparse, as the reader will judge from the information below. Crocuta crocuta [Spotted Hyaena] Lönnberg (1908) treated two forms of hyena as distinct species under two distinct scientific names.
As to the feasibility of the requisite mating, various YouTube videos document the fact that small dogs have been occasionally known to mate with hens. Further, it is well known that chickens will adopt the young of other types of animals, including dogs, as shown in the picture at right.
In fact, it would actually be impossible for a canid and a felid to hybridise, as some outlets are reporting. The cat differs from the domestic cat in several key ways, including its larger size - up to 90 centimetres (35 inches) long from head to tail-tip, very wide-set ears, short whiskers, and long canine teeth.
In the wild, cats would normally regard rabbits as prey, but in domestic settings there have been numerous observed mating between cats and rabbits. These have been matings in both directions i.e. buck rabbit and female cat, or tomcat and female rabbit. No pregnancies resulted.
Saluki. Salukis originally are a Middle Eastern dog and are one of the oldest dog breeds out there, going back to 10,000 BC. The breed is genetically very close to wolves.
What Is a Blue Heeler? As you might have guessed, Australian Cattle dogs originated Down Under in the 1840s, when a native Queenslander started breeding blue merle collies with Dingoes. The pups proved to be such good working dogs that their fame spread—and litters were snapped up by nearby cattle farmers.
The typical Carolina dog has pointed ears, a fox-like snout and a tail that curves like a fishhook when it is raised. They look similar to Australian Dingoes but, taxonomically, they fall under canis familiaris.
Other members of the wider dog family, Canidae, such as South American canids, true foxes, bat-eared foxes, or raccoon dogs which diverged 7 to 10 million years ago, are less closely related to the wolf-like canids, have fewer chromosomes and cannot hybridize with them.
In fact, such human-animal hybrids are often referred to as “chimeras”.
