Designer breed dogs are mixed-breed dogs intentionally bred from parents of two established breeds. [citation needed] Studies have shown that cross-bred dogs have a number of desirable reproductive traits. Scott and Fuller [45] found that cross-bred females were superior mothers compared to purebred females, producing more milk and giving ...
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 ...
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.
In the city of Teotihuacan, it was common practice to crossbreed coyotes and Mexican wolves with dogs in order to breed resistant, loyal but temperamental, good guardians. [3] Northern Indigenous peoples in Canada were mating coyotes and wolves to their sled dogs in order to produce more resilient animals as late as the early 20th century. [1]
"Dogs get 'stuck' during mating because the gland at the bottom of the male's penis swells up and becomes gripped by the contracting muscles in the female's vagina," MacMillan explains. "This ...
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. [1]
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. [1] By analogy, the term is used in human reproduction , but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious recessive traits resulting from ...
