A mixed-breed dog (also called a mutt, crossbreed, mongrel, tyke, cur, or random-bred dog) is a dog that is a mixture of two or more breeds, or a descendant of feral or pariah dog populations. Since, except for extreme variations in size, dogs interbreed freely, mixed-breed dogs vary in size, shape, and color, making them hard to classify physically.

Historically, all pure bred dogs have been selected from a mixed-breed population.

Terms for mixed-breed dogs
There is a profusion of words and phrases used for non-pure bred dogs. The words cur, tyke, and mongrel are generally viewed as derogatory in America, whereas in the United Kingdom mongrel is the unique technical word for a mixed-breed dog, and is not a term of disparagement when referring to a dog. Therefore, many American owners prefer mixed-breed.

Mutt is also used (in the U.S.A and Canada), sometimes in an affectionate manner. In Hawaii, mixed breed dogs are referred to as poi dog. Some American registries and dog clubs that accept mixed-breed dogs use the breed name All American, referring to the United States' reputation as a melting pot of different nationalities.

In South Africa, the tongue-in cheek expression pavement special is sometimes used as a description for a mixed-breed dog. Random-bred dog, mutt, and mongrel are often used for dogs who result from breeding without the supervision or planning of humans, especially after several generations, whereas mixed breed and crossbreed often imply mixes of known breeds, sometimes deliberately mated.

In Brazil and the Dominican Republic, the name for mixed-breed dogs is vira-lata (vira: to turn, to bring down; lata: tin can, trash can) because there are dogs without owners that feed on urban garbage on the streets, and often knock over trash cans to reach the food.

Slang terms are also common. Heinz 57 is often used for dogs of uncertain ancestry, in a playful reference to the "57 Varieties" slogan of the H. J. Heinz Company. In some countries, bitsa is common, meaning "bits o' this, bits o' that". A fice or feist is a small mixed-breed dog.

To complicate matters, many owners of crossbred dogs identify them—often facetiously—by an invented breed name constructed from parts of their parents' breed names. For example, a cross between a Pekingese and a Poodle is called a Peekapoo, possibly a play on peek-a-boo. As another example, one of the UK's Queen Elizabeth's famous Corgis mated with her sister's Dachshund, and the resulting offspring are referred to as Dorgis.

A cross-breed of a Beagle and a Basset is affectionately referred to as a Bagel. Many dogs in New York City which might previously have been described as Shepherd mixes are now referred to colloquially as Brooklyn Shepherds.

All possible body shapes, ear types, and tail styles can appear in mixed breeds. Extremes in appearance, however, such as the flattened face of the English Bulldog or the extremely curled tail of the Pug, seldom survive even the first crossbreeding. Mixed breeds also tend to have a size between that of their parents, thus tending eventually toward the norm.

Mixed-breed dogs can be any size, weight, or colour, but some colours are more common than others. No matter their parents' colours, mixed breeds are often a light-to-medium brown or black, frequently with a white chest and other white markings. The light-brown coat is sometimes called yellow, as personified by the fictional dog Old Yeller. A brown coat with black across the top and sides is also quite common.

Predicting the adult appearance of a mixed-breed puppy is difficult. Even purebred puppies do not look much like the adult dogs they will become, and with mixed-breed puppies it is nearly impossible. If one knows the breeds of the parents, some characteristics can be ruled out; for example, a cross between two small purebreds will not result in a dog the size of a Great Dane.

Some breeds tend to pass on their physical traits to mixes more than others. Border Collies and some Spaniels, for example, often produce offspring with similar coats and ears. The crossbred offspring of German Shepherds usually have Shepherd faces and other characteristics.

Tribute to Toby
"My favourite dog was a half breed, part Lab and Airedale. Named Toby. Great swimmer and hunted sniffing the air, but could track as well. Bobbed off his front legs on to his hind legs in short brush to flush game.  Would stay when commanded to do so and go right, left, beyond, or near by the use of hand signals. When near the fallen game Toby would respond to a circular search at a clapping sound and retrieve the game to me instantly and with a expected reward and show of acceptance.  Also new the difference between 5 and six sticks. New every stitch of clothes I wore and new the difference between them. Wouldn't fight dogs but could clean up on ground hogs which rooted up the orchard trees.  Was asked by strangers, upon meeting them in the field if he would bite. I told them only if you bite him first. Toby turned his head and looked up at me after I said that and the strangers understood that to mean that Toby understood what I meant.  Toby has passed away over 20 years now, but fond thoughts still remain. There may be another as smart as Toby was, which would take me longer than I have to write to dispute that fact, but there will never be another Toby. - Anon"

With each generation of indiscriminate mixing, the offspring move closer to the genetic norm. Dogs that are descended from many generations of mixes are typically light brown or black and weigh about 18 kg (40 lb). They typically stand between 38 and 57 cm (15 and 23 inches) tall at the withers.

Guessing a mixed-breed's unknown ancestry is difficult for even knowledgeable dog observers, because mixed breeds have much more genetic variation than among purebreds. For example, two white mixed-breed dogs might have recessive genes that produce a black coat and, therefore, produce offspring looking unlike their parents.

The theory of hybrid vigour suggests that dogs of mixed ancestry will be healthier than their purebred counterparts. In some cases this might be true, because inbreeding among purebreds has made some breeds prone to various genetic health problems. Mixed-breed dogs are less likely to have certain genetic disorders, as their parents come from a more diverse genetic pool so that detrimental recessive genes are less likely to occur in both parents.

For example, large dogs such as German Shepherd Dogs often suffer from hip dysplasia. Mating a German Shepherd carrier of the faulty gene with a dog from a breed not known to suffer genetic hip problems reduces the likelihood of producing offspring with the problem. On the other hand, breeding the Shepherd with another Shepherd whose ancestors do not have the genetic problem also has this effect.

Some pure bred dog breeds have difficulties associated simply with the exaggerated physical traits of the breed. For example, the French Bulldog has such small hips and such a large head that artificial insemination and Caesarean section are usually required to produce puppies.

Crossing such a dog with another breed will likely produce dogs without these reproductive difficulties, although most authorities on dog populations discourage reproduction among crossbreeds and mixed breeds because there are already so many purebreds available for adoption in addition to mixed breeds.

There is no guarantee of good genetic health of any dog, purebred or otherwise, as not all damaging genes are recessive. Also, of course, purebred and mixed-breed dogs are equally susceptible to nongenetic ailments, such as rabies, distemper, injury, and infestation by parasites.

Multiple generations of mixed breeds can result in mongrels with no distinct breed markers, such as this dog with chow chow, labrador retriever, and terrier traits, among others.

Types of mixed breeding

It's important to note that all dog breeds are man-made creations: dogs were traditionally bred for specific functions. All existing dog breeds began as mixed breeds, either by random occurrence or by deliberate crosses of existing breeds. Encouraging desirable traits and discouraging others, breeders sought to create their ideal appearance or behaviour, or both, for dogs, and, additionally, to ensure that the dogs could consistently produce offspring with the same appearance or behaviour.

Some consider mixed breeds undesirable, but mixing breeds can lead to desirable results, especially in the hands of an expert breeder. On the other hand, inexperienced cross breeders can produce disastrous results. For example, the offspring of an obsessive Border Collie and an energetic, destructive Terrier could be dogs whose behaviour is so erratic as to make the dogs a liability.

Mixed-breed dogs can be divided roughly into three types:

1. Crossbred dogs, which are mixtures of two known breeds. Some crossbreeds have traits that make them popular enough to be frequently bred deliberately, such as the Cockapoo—a cross between a Poodle and a Cocker Spaniel—and the Labradoodle, which mixes a Labrador Retriever with a Poodle. Other crossbreeds occur when breeders are hoping to create new breeds or to add or reinforce characteristics from one breed into another breed. Most crossbreeding, however, occur accidentally.

2. Mixes among more than two breeds, such as when a crossbred dog mates with a purebred dog or with another crossbreed. The term mongrel is sometimes used to distinguish these dogs from crossbreeds.

3. The generic canis familiaris, seen in feral or pariah dog populations, where mixed breeding has occurred over many generations. These dogs tend to be light brown and of medium height and weight. This "genetic average" might also represent the appearance of the modern dog's ancestor.

There is no scientific justification for the belief that a purebred bitch is in any way tainted after mating with a dog of another breed. Future mating with dogs of the same breed will produce purebred puppies.

Mixed breeds in dog sports

Both purebred and mixed-breed dogs can excel at dog sports, such as obedience, dog agility, flyball, and frisbee. Often, highly energetic mixed-breeds are left with shelters or rescue groups, where they are sought by owners with the caring, patience, and drive to train them for dog sports, turning unwanted dogs into healthy, mentally and physically stimulated award winners.

Historically, conformation shows and dog sports excluded mixed-breed dogs from competition. While this tradition is changing, some sports still remain open only to one breed of dog, such as greyhound racing, or to one type of dog, such as sheepdog trials open only to dogs of known herding ancestry. In the latter case, herding organizations now sometimes accept mixed-breed dogs who have evident herding-dog ancestry, such as Corgi mixes or Border Collie crosses.

Until the early 1980s, mixed-breed dogs were also generally excluded from obedience competitions. However, starting with the American Mixed Breed Obedience Registry (AMBOR) and the Mixed Breed Dog Club of America (MBDCA), which created obedience venues in which mixed-breed dogs could compete, more opportunities have opened up for all dogs in all dog sports.

Most dog agility and flyball organizations have always allowed mixed-breed dogs to compete. Today, mixed breeds have proved their worth in many performance sports.

Some kennel clubs, whose purpose is to promote purebred dogs, still exclude mixed breeds from their performance events. The AKC and the FCI are two prominent hold-outs. However, the AKC does allow mixed breeds to earn their Canine Good Citizen award.

In conformation shows, where dogs' conformation is evaluated, mixed-breed dogs normally cannot compete. For purebred dogs, their physical characteristics are judged against a single breed standard. Mixed-breed dogs, however, are difficult to classify except according to height; there is tremendous variation in physical traits such as coat, skeletal structure, gait, ear set, eye shape and colour, and so on.

When conformation standards are applied to mixed-breed dogs, such as in events run by the MBDCA, the standards are usually general traits of health, soundness, symmetry, and personality. The Kennel Club (UK) operates a show called Scruffts (a name derived from its prestigious Crufts show) open only to mixed-breeds in which dogs are judged on character, health, and temperament.

Advantages and drawbacks

The mature appearance and behaviour of purebred puppies is more predictable than that of mixed breeds, including cross-breeds. With purebred dogs, the genetic variations are well documented and a breeder has a fair estimation of what type of offspring a given pair will produce. Even still, there is variation within breeds; for example, two champion sheep-herding Border Collies might produce offspring with no interest in sheep herding.

Mixed breed dogs are, on average, no more intelligent than purebred dogs, and both sets feature both slow learners and dogs with high learning capacity. For example, Benji, the hero in a series of films named for him, was a mixed-breed terrier. However, it is more difficult to predict the trainability of mixed-breed dogs when they are very young.

Most Golden Retrievers are eager to please, but a mix of a Golden with the independent Siberian Husky could inherit either dog's trainability—or you could get a dog with the endurance and athleticism of the Siberian and the trainability of the Golden.

Many people enjoy owning mixed breeds, valuing their unique appearance and characteristics; while dogs of some breeds, such as the Tervueren, exhibit little variability of appearance, mixed-breed dogs exhibit often unique appearances. Although some dog owners have a specific breed of dog they wish to acquire, and will never accept a mixed breed, many others enjoy mixed-breed dogs that exhibit characteristics similar to their favourite breeds; in fact, with a mixed breed, they can enjoy some aspects of appearance and personality of two favourite breeds with a single dog.

There is usually an abundant supply of mixed-breed dogs wanting owners, available at negligible prices, while pedigreed dogs can cost hundreds or thousands of dollars and reputable breeders can be hard to find.

Some owners value a dog's pedigree as a status symbol and, therefore, have no use for mixed-breed dogs, whose market value is effectively zero; others particularly appreciate the physical or behavioural traits of certain breeds; still others ignore pedigree and, instead, value a dog's personality and health. In short, most dog owners believe that their dog's breed—and specifically his or her own dog—is the best sort of dog there is.

Finally, one of the best sources for both purebred and mixed breed dogs are your local animal shelters. The cost is low and many of the animals are housebroken.
