Dog saliva has been said by many cultures to have curative powers in people. [46] [47] "Langue de chien, langue de médecin" is a French saying meaning "A dog's tongue is a doctor's tongue", and a Latin quote that "Lingua canis dum lingit vulnus curat" or "A dog's saliva can heal your wound" appears in a thirteenth-century manuscript. [48]
Classical conditioning occurs when a conditioned stimulus (CS) is paired with an unconditioned stimulus (US). Usually, the conditioned stimulus is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).
This sound was presented to the dogs along with food, which acted as an unconditioned stimulus. The presentation of a neutral stimulus does not result in any particular response, but the presentation of an unconditioned stimulus results in an unconditioned response, which was the dogs salivating in Pavlov's experiments.
Ivan Petrovich Pavlov (Russian: Иван Петрович Павлов, IPA: [ɪˈvan pʲɪˈtrovʲɪtɕ ˈpavləf] ⓘ; 26 September [O.S. 14 September] 1849 – 27 February 1936) [2] was a Russian and Soviet experimental neurologist and physiologist known for his discovery of classical conditioning through his experiments with dogs.
Adult dogs Most adult dogs need to pee about three to five times a day. Factors such as size, breed, and activity level affect urination frequency. Lots of dogs like to pee on things when they are ...
Dogs with tooth decay may experience pain when eating, especially hard food, and may avoid meals or show discomfort. Hypersalivation Excessive dog drooling can be a response to pain or infection ...
However, the dogs did learn something - the presentation of the metronome predicted the absence of the food. This phenomenon we now call "conditioned inhibition." However, since Pavlov was studying conditioned excitation, by measuring drops of saliva, he could not experimentally measure the inhibition of salivation.
The Neapolitan Mastiff has a lot of excess skin plus droopy jowls which make drooling impossible to avoid. They are huge dogs, reaching weights of up to 150 pounds with a standing height of around ...
