Tracking (dog)
Tracking refers to a dog's ability to detect, recognize and follow a specific scent. Possessing heightened olfactory abilities, dogs, especially scent hounds, are able to detect, track and locate the source of certain odours.Hepper, P. G., & Wells, D. L. (2005). How many footsteps do dogs need to determine the direction of an odour trail?. Chemical Senses, 30(4), 291–298. A deeper understanding of the physiological mechanisms and the phases involved in canine scent tracking has allowed humans to utilize this animal behaviour in a variety of professions. Through domestication and the human application of dog behaviour, different methods and influential factors on tracking ability have been discovered. While tracking was once considered a predatory technique of dogs in the wild, it has now become widely used by humans. Physiological mechanisms According to zoosemiotics animal communication involves an exchange of information between a sender and a receiver through a transfer of ...

Male Weimeraner Following A Scent Trail In The Snow
Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilization. A male organism cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. Not all species share a common sex-determination system. In most animals, including humans, sex is determined genetically; however, species such as ''Cymothoa exigua'' change sex depending on the number of females present in the vicinity. In humans, the word ''male'' can also be used to refer to gender in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineages, an example ...

Scent Hound
Franz Rudolf Frisching in the uniform of an officer of the Bernese Huntsmen Corps with his Berner Laufhund, painted by Jean Preudhomme in 1785 Scent hounds (or scenthounds) are a Dog type, type of hound that primarily hunts by scent rather than visual perception, sight. These breeds are hunting dogs and are generally regarded as having some of the most sensitive noses among dogs. Scent hounds specialize in following scent or smells. Most of them tend to have long, drooping ears and large nasal cavities to enhance smell sensitivity. They relatively need to have high endurance to be able to keep track of scent over long distances and rough terrain. It is believed that they were originally bred by the Celts. Description Hounds are hunting dogs that either hunt by following the scent of a game animal (''scent hounds'') or by following the animal by sight (sighthounds). There are many breeds in the ''scent hound type'', and scent hounds may do other work as well, so exactly which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leash
A leash (also called a lead, lead line or tether) is a rope or similar material used to control an animal by attaching it to a collar, harness, or halter. In British English, a leash is generally for a larger (possibly dangerous or aggressive) animal, with lead being more commonly used when walking a dog. Types of leashes Leashes take many forms; for example: * A simple metal chain. * Very short tab leashes; a clip attached to a loop handle or to a short piece of leather with a knot or similar short handle. Allows very close, tight control of a dog in certain competition or training situations. * Short, soft, braided leather leash with a loop handle and a clip to attach to the collar, usually about 4 feet in length, commonly used during obedience training. The softness enables the trainer to fold the leash into a shorter length and the braiding allows a firmer grip. * Nylon webbing leash, also known as a tracking/training leash in the UK, usually 4 to 6 feet, with ...

Schutzhund Trial, Tracking Test
Schutzhund (/'ʃʊtshʊnt/, German for "protection dog"), currently known competitively as IGP and previously as IPO, is a dog sport that tests a dog's tracking, obedience, and protection skills, and evaluates if a dog has the appropriate traits and characteristics of a good working dog. It was developed in Germany in the early 1900s as a suitability test for German Shepherds, but soon became the model for training and evaluating all five of the German protection breeds, which included Boxer, Dobermann, Riesenschnauzer, and Rottweiler. Though any breed of dog can participate, today the sport is dominated by German Shepherds and the Belgian Malinois breed. Dog owners and handlers participate in Schutzhund clubs as a group activity for training the dogs, and clubs sponsor trials to test the dogs and award titles. The best dogs can qualify to participate in national and international level championships. Traits of Schutzhund dogs Schutzhund tests dogs for the traits necessary ...

Tracking (hunting)
Tracking in hunting and ecology is the science and art of observing animal tracks and other signs, with the goal of gaining understanding of the landscape and the animal being tracked (the "quarry"). A further goal of tracking is the deeper understanding of the systems and patterns that make up the environment surrounding and incorporating the tracker. The practice of tracking may focus on, but is not limited to, the patterns and systems of the local animal life and ecology. Trackers must be able to recognize and follow animals through their tracks, signs, and trails, also known as spoor. Spoor may include tracks, scat, feathers, kills, scratching posts, trails, drag marks, sounds, scents, marking posts, the behavior of other animals, habitat cues, and any other clues about the identity and whereabouts of the quarry. The skilled tracker is able to discern these clues, recreate what transpired on the landscape, and make predictions about the quarry. The tracker may attempt to ...

Scent
An odor (American English) or odour (Commonwealth English; see spelling differences) is caused by one or more volatilized chemical compounds that are generally found in low concentrations that humans and animals can perceive via their sense of smell. An odor is also called a "smell" or a "scent", which can refer to either a pleasant or an unpleasant odor. While "odor" and "smell" can refer to pleasant and unpleasant odors, the terms "scent", "aroma", and "fragrance" are usually reserved for pleasant-smelling odors and are frequently used in the food and cosmetic industry to describe floral scents or to refer to perfumes. Physiology of smell Sense of smell The perception of odors, or sense of smell, is mediated by the olfactory nerve. The olfactory receptor (OR) cells are neurons present in the olfactory epithelium, which is a small patch of tissue at the back of the nasal cavity. There are millions of olfactory receptor neurons that act as sensory signaling cells. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bloodhound Trials Feb 2008 -153 (2307360048)
The bloodhound is a large scent hound, originally bred for hunting deer, wild boar and, since the Middle Ages, for tracking people. Believed to be descended from hounds once kept at the Abbey of Saint-Hubert, Belgium, in French it is called, ''le chien de Saint-Hubert''. This breed is famed for its ability to discern human scent over great distances, even days later. Its extraordinarily keen sense of smell is combined with a strong and tenacious tracking instinct, producing the ideal scent hound, and it is used by police and law enforcement all over the world to track escaped prisoners, missing people, and lost pets. Appearance Bloodhounds weigh from 36 to 72 kg (80 to 160 lbs). They are 58 to 69 cm (23 to 27 inches) tall at the withers. According to the AKC standard for the breed, larger dogs are preferred by conformation judges. Acceptable colors for bloodhounds are black, liver, and red.

Zoosemiotics
Zoosemiotics is the semiotic study of the use of signs among animals, more precisely the study of semiosis among animals, i.e. the study of how something comes to function as a sign to some animal. It is the study of animal forms of knowing. Considered part of biosemiotics, zoosemiotics is related to the fields of ethology and animal communication. It was developed by semiotician Thomas Sebeok based on the theories of German-Estonian biologist Jakob von Uexküll. The field is defined by having as its subject matter all of those semiotic processes that are shared by both animals and humans. The field also differs from the field of animal communication in that it also interprets signs that are not communicative in the traditional sense, such as camouflage, mimicry, courtship behavior etc. The field also studies cross-species communication, for example between humans and animals. See also *Biosemiotics *Phytosemiotics Phytosemiotics is a branch of biosemiotics that studies the sign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
