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.
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).

The history of animal testing goes back to the writings of the Ancient Greeks in the 4th and 3rd centuries BCE, with Aristotle (384–322 BCE) and Erasistratus (304–258 BCE) one of the first documented to perform experiments on nonhuman animals.

In Pavlov's original demonstration of classical conditioning, he used a backward conditioning arrangement as the control condition. Briefly, in that procedure, the dogs experienced the same number of US presentations (food) and the same number of CS presentations (metronome ticking) as the experimental groups, but the timing of the CS and US ...
Tacking onto this, Milan says it’s important that your dog knows they can trust you. “I encourage a relationship of trust, respect, and love with every dog,” he emphasizes.
The popular experiment is known as Pavlov's dogs where food was provided to the dogs along with repeated sounds of a bell; the food, which was the initial stimulus, would cause the dog to salivate. [6] The pairing of the bell with the food resulted in the former becoming the new stimulus even after the food was excluded from the pairing. [6]
Though Zeliony was still officially an employee of the state-run laboratory under Pavlov's leadership, in 1921, he attempted to found his own institute for the study of animal behaviour. Zeliony's proposal to secure funding for his project from the government was criticized by Pavlov and rejected (Todes 1998: 38–39). [11]
