Bark (utterance)
A bark is a sound most often produced by dogs. Other animals that make this noise include, but are not limited to, wolves, coyotes, foxes, seals, frogs and owls. "Bark" is also a verb that describes the sound of many canids. Definition There is no precise, consistent, and functional acoustic definition for barking, but researchers classify barks according to several criteria. Researchers at the University of Massachusetts Amherst and Hampshire College have defined a bark as a short, abrupt vocalization that is relatively loud and high-pitched, changes in frequency, and often repeats rapidly in succession.Lord, Kathryn., Feinstein, Mark., Coppinger, RaymondBarking and mobbing. ''Behavioural Processes''. 2009. Barking in dogs Dog barking is distinct from wolf barking. Wolf barks represent only 2.4% of all wolf vocalizations, in warning, defense, and protest. In contrast, dogs bark in many social situations, with acoustic communication in dogs being described as hypertrophi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A Dog Mid-bark
A, or a, is the first Letter (alphabet), letter and the first vowel letter of the Latin alphabet, used in the modern English alphabet, and others worldwide.

The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version is often written in one of two forms: the double-storey and single-storey . The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English, ''English articles, a'' is the indefinite article, with the alternative form ''an''. Name In English, the name of the letter is the ''long A'' sound, pronounced . Its name in most other languages matches the letter's pronunciation in open syllables. History The earliest know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgical Procedure
Surgery is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass), to reconstruct or alter aesthetics and appearance (cosmetic surgery), or to remove unwanted tissue (biology), tissues (body fat, glands, scars or skin tags) or foreign bodies. The act of performing surgery may be called a surgical procedure or surgical operation, or simply "surgery" or "operation". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments, operating theater, surgical facility or surgical nurse. Most surgical procedures are performed by a pair of operators: a surgeon who is the main operator performing the surgery, and a surgical assistant who provides in-procedure manual assistance during surgery.

Euthanasia
Euthanasia (from : + ) is the practice of intentionally ending life to eliminate pain and suffering. Different countries have different Legality of euthanasia, euthanasia laws. The British House of Lords Select committee (United Kingdom), select committee on medical ethics defines euthanasia as "a deliberate intervention undertaken with the express intention of ending a life to relieve intractable suffering". In the Netherlands and Belgium, euthanasia is understood as "termination of life by a doctor at the request of a patient". The Dutch law, however, does not use the term 'euthanasia' but includes the concept under the broader definition of "assisted suicide and termination of life on request". Euthanasia is categorised in different ways, which include Voluntary euthanasia, voluntary, Non-voluntary euthanasia, non-voluntary, and Involuntary euthanasia, involuntary.

Electric Shock
An electrical injury (electric injury) or electrical shock (electric shock) is damage sustained to the skin or internal organs on direct contact with an electric current. The injury depends on the Current density, density of the current, tissue resistance and duration of contact. Very small currents may be imperceptible or only produce a light tingling sensation. However, a shock caused by low and otherwise harmless current could startle an individual and cause injury due to jerking away or falling. A strong electric shock can often cause painful Spasm, muscle spasms severe enough to Joint dislocation, dislocate joints or even to Bone fracture, break bones. The loss of muscle control is the reason that a person may be unable to release themselves from the electrical source; if this happens at a height as on a Overhead power line, power line they can be thrown off. Larger currents can result in tissue damage and may trigger ventricular fibrillation or cardiac arrest. If death res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Calming Signals
Calming signals is a term conceived by Norwegian dog trainer and canine ethologist, Turid Rugaas, to describe the patterns of behavior used by dogs interacting with each other in environments that cause heightened stress and when conveying their desires or intentions. The term has been used interchangeably with "appeasement signals." Calming signals, or appeasement signals, are communicative cues used by dogs to de-escalate aggressive encounters or to prevent the development of aggressive encounters completely. Calming signals are performed by one dog (the sender) and directed towards one or more individual(s) (the recipient(s)), which could be dogs or individuals of other species, such as humans. When calming signals are ignored, a dog may display warning signals of aggression, and this has the potential to escalate to outright conflict between individuals. The domestication of dogs by humans has significantly altered the behavioral patterns observed in ancestral species, suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operant Conditioning
Operant conditioning, also called instrumental conditioning, is a learning process in which voluntary behaviors are modified by association with the addition (or removal) of reward or aversive stimuli. The frequency or duration of the behavior may increase through reinforcement or decrease through punishment or Extinction (psychology), extinction. Origins Operant conditioning originated with Edward Thorndike, whose law of effect theorised that behaviors arise as a result of consequences as satisfying or discomforting. In the 20th century, operant conditioning was studied by Behaviorism, behavioral psychologists, who believed that much of mind and behaviour is explained through environmental conditioning. Reinforcements are environmental stimuli that increase behaviors, whereas punishments are stimuli that decrease behaviors. Both kinds of stimuli can be further categorised into positive and negative stimuli, which respectively involve the addition or removal of environmental stim ...

Clicker Training
Clicker training is a positive reinforcement animal training method based on a bridging stimulus ( the clicker) in operant conditioning. The system uses conditioned reinforcers, which a trainer can deliver more quickly and more precisely than primary reinforcers such as food. The term "clicker" comes from a small metal cricket noisemaker adapted from a child's toy that the trainer uses to precisely mark the desired behavior. When training a new behavior, the clicker helps the animal to quickly identify the precise behavior that results in the treat. The technique is popular with dog trainers, but can be used for all kinds of domestic and wild animals. Sometimes, instead of a click to mark the desired behavior, other distinctive sounds are made (such as a "whistle, a click of the tongue, a snap of the fingers, or even a word") [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Separation Anxiety In Dogs
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.
