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.
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.
A working dog is a dog used to perform practical tasks, as opposed to pet or companion dogs.
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 (CPIV), 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 health of dogs is a well studied area in veterinary medicine.
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.
Phycomycosis is an uncommon condition of the gastrointestinal tract and skin most commonly found in dogs and horses. The condition is caused by a variety of molds and fungi, and individual forms include pythiosis, zygomycosis, and lagenidiosis. Pythiosis is the most common type and is caused by Pythium, a type of water mould. Zygomycosis can also be caused by two types of zygomycetes, Entomophthorales and Mucorales. The latter type of zygomycosis is also referred to as mucormycosis. Lagenidiosis is caused by a Lagenidium species, which like Pythium is a water mould. Since both pythiosis and lagenidiosis are caused by organisms from the class Oomycetes, they are sometimes collectively referred to as oomycosis.
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 the practice of spinal manipulation or manual therapy for animals. Veterinary chiropractors typically treat horses, racing greyhounds, and pets. Veterinary chiropractic is a fast-developing field that is complementary to the conventional approach. Veterinary chiropractic is considered a controversial method due to limited evidence that exists on the efficacy of osteopathic or chiropractic methods in equine therapy. There is limited evidence supporting the effectiveness of spinal manipulation or mobilization for equine pain management, and the efficacy of specific equine manual therapy techniques is mostly anecdotal.
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.
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 over 48% of households have a pet dog.
Tail chasing is a behaviour exhibited in dogs that is characterized by spinning in tight circles in either direction, and can be slow and focused on the tail or fast and unfocused. It is a compulsion similar to those seen in humans suffering from OCD and it can be quite disruptive to the lives of the dogs themselves, as well as their owners. Some causes have been suggested, including genetic factors, and environmental factors that vary depending on the individual dog. Furthermore, treatment options include drugs that decrease the frequency of tail chasing by targeting the underlying mechanisms, and behavioural changes regulated by the dog's owners.
