This essay has searches charakter and is about Interspecies crosses in the genus Canis.
Top topics are mainly about this speciesis: wolf, coyote, jackales and it mainly gulden jackal.
In this essay are broadly hold two parts. Specifically the first part introduce individual species, which are present bastardization. There are introduce every above mentioned species. For each species is describe appearance, distribution, diet, behavior. For every species is dangerous and CITES and IUCN protection. The second part is Interspecies crosses. In this part are concretely cases interspecies crosses, especially mating between dogs. Exception are wolves and jackals, who can maiting and produce puppies, who are call 'coywolf'. Own name have wolf x dog hybrids, concretely 'wolfdog'. There is not only bastardization between species, but sometimes between some subspecies and this problem have mainly wolves. This caces and problems are for example on The Apennine peninsula.
Interspecies crosses is the most extensive in continent America, mainly in North America. There are encounter wolves and coyotes. But the most explore encounter is between wolves and dogs, whose descendants are fertile and bring unclean gene to purebred animals. Result in this hybridization is unclean gene pool of all population. But wolf and dog hybrid is too in Europe. Proved are for example in Estonia, Latvia and the Caucasus. There is a conflict with stray dogs or pastoral dogs who guard the free-ranging herds of farm animals.
Wolf x dog hybridation is reason of birth of two races like is Czechoslovakia wolfdog and Saarloos wolfdog. On start of both this races was wolf´s females. Interspecies crosses of jackals is not study so much. The most often is breeding with stray dogs or wild dogs. But in Bulgaria are notes about mating between jackal and wolf.
