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 ...
Virgin dogs can become quite distressed at finding themselves unable to separate during their first copulation, and may try to pull away or run. Dog breeders often suggest it is appropriate for handlers to attempt to calm the mating dogs if they show anxiety once this stage is reached.

Animal non-reproductive sexual behavior encompasses sexual activities that non-human animals participate in which do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals, recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals.

Many animal species have specific mating (or breeding) periods e.g. (seasonal breeding) so that offspring are born or hatch at an optimal time. In marine species with limited mobility and external fertilisation like corals , sea urchins and clams , the timing of the common spawning is the only externally visible form of sexual behaviour.
Animal breeding is a branch of animal science that addresses the evaluation (using best linear unbiased prediction and other methods) of the genetic value (estimated breeding value, EBV) of livestock. Selecting for breeding animals with superior EBV in growth rate, egg, meat, milk, or wool production, or with other desirable traits has ...
Snuppy (Korean: 스너피, romanized: Seuneopi, a portmanteau of "SNU" and "puppy"; April 24, 2005 – May 2015) [2] was an Afghan hound, the first dog clone.The puppy was created using a cell from an ear from an adult Afghan hound and involved 123 surrogate mothers, of which only two produced pups (Snuppy being the sole survivor).
In these puppy mills, breeding dogs are often subjected to living the entirety of their lives in cages, which are cramped and uncomfortable for the dog. The whelping bitch's needs often go unmet or ignored. An estimated 500,000 dogs are kept solely for the purpose of breeding in puppy mills. [7] [better source needed]
