Littermate syndrome (sometimes referred to as littermate dependency) is a blanket term for a variety of behavioral problems in dogs, which are attributed to their being raised alongside other dogs of the same age (regardless of whether they are actually from the same litter). The existence of littermate syndrome is disputed.
Behaviors which have been connected to littermate syndrome include leash reactivity, fear aggression, neophobia, and separation anxiety relative to the other dog, [1] as well as aggression towards each other and towards their owner. [2]
The American Kennel Club posits that littermate syndrome is the result of puppies "bond[ing] more closely with each other than with [their owner]", arguing that they will distract each other during training and thereby mutually impede their socialization. [3]
A 2019 article in the Journal of the International Association of Animal Behavior Consulants argues that there is no scientific evidence of littermate syndrome existing, only anecdotal, and that the syndrome's various aspects all have different causes, including poor management of the dogs' environment, and insufficient opportunities for behavioral enrichment; as well, the article emphasizes that many dogs are raised alongside their siblings without the occurrence of littermate syndrome, and further suggests that the label "syndrome" may wrongly give the impression that the behavioral problems are irremediable. [4]
Biologist and ethologist Marc Bekoff has declared it to be a "myth", specifying that while the relevant behaviors may be real, the overall phenomenon is "rare enough not to warrant being called a syndrome". [5]
The beagle is a breed of small scent hound, similar in appearance to the much larger foxhound. The beagle was developed primarily for hunting rabbit or hare, known as beagling. Possessing a great sense of smell and superior tracking instincts, the beagle is the primary breed used as a detection dog for prohibited agricultural imports and foodstuffs in quarantine around the world. The beagle is a popular pet due to its size and good temper.
The dachshund, also known as the wiener dog or sausage dog, badger dog and doxie, is a short-legged, long-bodied, hound-type dog breed. The dog may be smooth-haired, wire-haired, or long-haired, with varied coloration.
The Shiba Inu is a breed of hunting dog from Japan. A small-to-medium breed, it is the smallest of the six original dog breeds native to Japan. Its name literally translates to "brushwood dog", as it is used to flush game.
The American Kennel Club (AKC) is a registry of purebred dog pedigrees in the United States. In addition to maintaining its pedigree registry, this kennel club also promotes and sanctions events for purebred dogs, including the Westminster Kennel Club Dog Show, an annual event which predates the official forming of the AKC, the National Dog Show and the AKC National Championship. The AKC is a non-member partner with the Fédération Cynologique Internationale. The AKC recognizes 200 dog breeds, as of 2022.
The Cavalier King Charles Spaniel (CKCS) is a British breed of toy dog of spaniel type. Four colours are recognised: Blenheim, tricolour (black/white/tan), black and tan, and ruby; the coat is smooth and silky. The lifespan is usually between eight and twelve years.
Dog breeding is the practice of mating selected dogs with the intention of maintaining or producing specific qualities and characteristics. When dogs reproduce without such human intervention, their offspring's characteristics are determined by natural selection, while "dog breeding" refers specifically to the artificial selection of dogs, in which dogs are intentionally bred by their owners. Breeding relies on the science of genetics, hence a breeder who is knowledgeable on canine genetics, health, and the intended purpose of the dogs attempts to breed suitable dogs.
The English Cocker Spaniel is a breed of gun dog. It is noteworthy for producing one of the most varied numbers of pups in a litter among all dog breeds. The English Cocker Spaniel is an active, good-natured, sporting dog standing well up at the withers and compactly built. There are "field" or "working" cockers and "house" cockers. It is one of several varieties of spaniel and is the foundation of its American cousin, the American Cocker Spaniel. The English Cocker is closer to the working-dog form of the Field Spaniel and the English Springer Spaniel. English Cocker Spaniels are also known as the "Merry Spaniel" due to their constantly wagging tail.
The Kerry Blue Terrier is a breed of dog. Originally bred to control vermin including rats, rabbits, badgers, ferrets, foxes, otters, hares, deer, and even wolves, over time the Kerry became a general working dog used for a variety of jobs including herding cattle and sheep. Despite a Kerry Blue winning Crufts in 2000, it remains an "unfashionable" breed, and is distinctly uncommon; however, it is not as threatened as some of the other terrier breeds such as the Skye Terrier, Sealyham Terrier, and Dandie Dinmont Terrier.
Crate training is the process of training a pet to tolerate confinement in a dog crate or cage. Crate advocates often claim that dogs are "den-dwelling" animals and that a crate can become a "den" substitute and a familiar and safe location for the pet. Most puppies can eventually tolerate crate training if it is introduced properly. The initial stress from being confined can give way to "increased feelings of security, safety, and comfort" after repeated exposure to the crate. Long-term or excessive crate confinement "may lead to emotional and behavioral deterioration over time." On the other hand, if properly done, crate training can play a major role in housebreaking a dog as fast as possible. Confining a dog in a crate or cage restricts its movement and freedom, If crate training is not taken seriously, the dog may start soiling around the house.
Dog training is a kind of animal training, the application of behavior analysis which uses the environmental events of antecedents and consequences to modify the dog behavior, either for it to assist in specific activities or undertake particular tasks, or for it to participate effectively in contemporary domestic life. While training dogs for specific roles dates back to Roman times at least, the training of dogs to be compatible household pets developed with suburbanization in the 1950s.
Dog aggression expressed by dogs is considered to be normal behaviour and various types of aggression are influenced by a dog's environment and genetic predisposition. Dogs commonly display possessive aggression when defending resources or themselves.
A kennel is a structure or shelter for dogs. Used in the plural, the kennels, the term means any building, collection of buildings or a property in which dogs are housed, maintained, and bred. A kennel can be made out of various materials, the most popular being wood and canvas. The term "kennel" can also refer to a dog crate or doghouse.
In some countries there is an overpopulation of pets such as cats, dogs, and exotic animals. In the United States, six to eight million animals are brought to shelters each year, of which an estimated three to four million are subsequently euthanized, including 2.7 million considered healthy and adoptable. Euthanasia numbers have declined since the 1970s, when U.S. shelters euthanized an estimated 12 to 20 million animals. Most humane societies, animal shelters and rescue groups urge animal caregivers to have their animals spayed or neutered to prevent the births of unwanted and accidental litters that could contribute to this dynamic.
The Dobermann is a German breed of medium-large working dog of pinscher type. It was originally bred in Thuringia in about 1890 by Louis Dobermann, a tax collector. It has a long muzzle and – ideally – an even and graceful gait. The ears were traditionally cropped and the tail docked, practices which are now illegal in many countries.
A puppy is a juvenile dog, generally one less than 12-18 months old.
Temperament tests assess dogs for certain behaviors or suitability for dog sports or adoption from an animal shelter by observing the animal for unwanted or potentially dangerous behavioral traits, such as aggressiveness towards other dogs or humans, shyness, or extreme fear.
Rage syndrome is a rare seizure disorder in dogs, characterized by explosive aggression.
Socialization of animals is the process of training animals so that they can be kept in close relationship to humans.
