Dog appeasing pheromone (DAP), sometimes known as apasine, is a mixture of esters of fatty acids released by the sebaceous glands in the inter-mammary sulcus of lactating female dogs. It is secreted from between three and four days after parturition and two to five days after weaning. [1] DAP is believed to be detected by the vomeronasal organ (Jacobson's organ) [1] and has an appeasing effect on both adults and pups, [1] and assists in establishing a bond with the mother. [2]
Synthetic DAP analogues have been developed which may support dogs during some, but not all, stressful situations. [3] [4] [5] [6] [7]
Synthetic DAP analogues have been developed (e.g. "Adaptil" [7] ); however, there is mixed evidence for the efficacy of synthetic DAP in reducing stress-related behaviours. [8] [9]
Synthetic DAP can be effective at reducing stress-related behaviours in a number of contexts [10] including puppies enrolled in socialization classes. [11] A double-blind, placebo-controlled study found that newly adopted puppies aged 6 to 10 weeks cried less when exposed to synthetic DAP, but only in gun-dog breeds. [12] It has been found to be highly effective in fear behaviours relating to sound sensitivity and fear of noises (e.g. fireworks and thunder). [2]
Synthetic DAP is ineffective for dogs housed in long-term kenneling facilities [10] and does not reduce soiling behaviour in newly adopted puppies. [12]
In 2014, a critical review of studies on the use of synthetic DAP in veterinary hospital wards concluded that there was "little or no robust evidence" of it being effective in this environment. [7]
The Chow Chow is a spitz-type of dog breed originally from Northern China. The Chow Chow is a sturdily built dog, square in profile, with a broad skull and small, triangular, erect ears with rounded tips. The breed is known for a very dense double coat that is either smooth or rough. The fur is particularly thick in the neck area, giving it a distinctive ruff or mane appearance. The coat may be shaded/self-red, black, blue, cinnamon/fawn, or cream.
Neutering, from the Latin neuter, is the removal of a non-human animal's reproductive organ, either all of it or a considerably large part. The male-specific term is castration, while spaying is usually reserved for female animals. Colloquially, both terms are often referred to as fixing. In male horses, castrating is referred to as gelding. An animal that has not been neutered is sometimes referred to as entire or intact.
The Old English Sheepdog is a large breed of dog that emerged in England from early types of herding dog. Obsolete names for the breed include Shepherd's Dog and bob-tailed sheep-dog. The nickname Bob-tail originates from how dogs of the breed traditionally had their tails docked. Old English Sheepdogs can grow very long coats with fur covering the face and eyes and do not shed unless brushed.
Dog communication is the transfer of information between dogs, as well as between dogs and humans. Behaviors associated with dog communication are categorized into visual and vocal. Visual communication includes mouth shape and head position, licking and sniffing, ear and tail positioning, eye gaze, facial expression, and body posture. Dog vocalizations, or auditory communication, can include barks, growls, howls, whines and whimpers, screams, pants and sighs. Dogs also communicate via gustatory communication, utilizing scent and pheromones.
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.
Kennel cough is an upper respiratory infection affecting dogs. There are multiple causative agents, the most common being the bacterium Bordetella bronchiseptica, followed by canine parainfluenza virus, and to a lesser extent canine coronavirus. It is highly contagious; however, adult dogs may display immunity to reinfection even under constant exposure. Kennel cough is so named because the infection can spread quickly among dogs in the close quarters of a kennel or animal shelter.
Skin disorders are among the most common health problems in dogs, and have many causes. The condition of a dog's skin and coat is also an important indicator of its general health. Skin disorders of dogs vary from acute, self-limiting problems to chronic or long-lasting problems requiring life-time treatment. Skin disorders may be primary or secondary in nature, making diagnosis complicated.
The Dobermann is a German breed of medium-large domestic 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.
Canid alphaherpesvirus 1 (CaHV-1), formerly Canine herpesvirus (CHV), is a virus of the family Herpesviridae which most importantly causes a fatal hemorrhagic disease in puppies less than two to three weeks old. It is known to exist in the United States, Canada, Australia, Japan, England and Germany. CHV was first recognized in the mid-1960s from a fatal disease in puppies.
The dog is a domesticated descendant of the wolf. Also called the domestic dog, it was domesticated from an extinct population of Pleistocene wolves over 14,000 years ago. The dog was the first species to be domesticated by humans. Experts estimate that hunter-gatherers domesticated dogs more than 15,000 years ago, which was before the development of agriculture. Due to their long association with humans, dogs have expanded to a large number of domestic individuals and gained the ability to thrive on a starch-rich diet that would be inadequate for other canids.
Canine reproduction is the process of sexual reproduction in domestic dogs, wolves, coyotes and other canine species.
Vaccination of dogs is the practice of animal vaccination applied to dogs. Programs in this field have contributed both to the health of dogs and to the public health. In countries where routine rabies vaccination of dogs is practiced, for example, rabies in humans is reduced to a very rare event.
Dog behavior is the internally coordinated responses of individuals or groups of domestic dogs to internal and external stimuli. It has been shaped by millennia of contact with humans and their lifestyles. As a result of this physical and social evolution, dogs have acquired the ability to understand and communicate with humans. Behavioral scientists have uncovered a wide range of social-cognitive abilities in domestic dogs.
Sophia Yin was a veterinarian, applied animal behaviorist, author and lecturer. She was a pioneer in the use of positive reinforcement for training dogs, and was widely recognized as an expert in the training of pets.
A cat pheromone is a chemical molecule, or compound, that is used by cats and other felids for communication. These pheromones are produced and detected specifically by the body systems of cats and evoke certain behavioural responses.
Veterinary chiropractic, also known as animal chiropractic, is chiropractic for animals – a type of spinal manipulation. Veterinary chiropractors typically treat horses, racing greyhounds, and pets. Veterinary chiropractic is a controversial method due to a lack of evidence as to the efficacy of chiropractic methods. Contrary to traditional medicine, chiropractic therapies are alternative medicine. There is some degree of risk associated with even skilled manipulation in animals as the potential for injury exists with any technique used. The founder of chiropractic, Daniel David Palmer, used the method on animals, partly to challenge claims that the placebo effect was responsible for favorable results in humans. Chiropractic treatment of large animals dates back to the early 1900s. As of 2019, many states in the US provide statutory or regulatory guidelines for the practice of chiropractic and related treatments on animals, generally requiring some form of veterinary involvement.
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.
Separation anxiety in dogs describes a condition in which a dog exhibits distress and behavior problems when separated from its handler. Separation anxiety typically manifests within minutes of departure of the handler. It is not fully understood why some dogs suffer from separation anxiety and others do not. The diagnosis process often leads to a misdiagnosis as it is difficult to differentiate from other medical and behavioral problems. The behavior may be secondary to an underlying medical condition. With chronic stress, impairments to physiological health can manifest. Increased stress in the dog alters hormone levels, thus decreasing natural immunity to various health problems. Separation anxiety can be treated with systematic desensitization and, if necessary, medication. Ignoring or punishing the dog, leaving them to "cry it out" does not solve separation anxiety and can damage the mental health of dogs.
Human–canine bonding is the relationship between dogs and humans. This relationship can be traced back to at least 15,000 years ago, to the Bonn-Oberkassel dog, who was found buried alongside two humans. For centuries, dogs have been considered man's best friend. This is most evident in Western countries, such as the United States, where 44% of households have a pet dog.
