to house or own a dog hybrid of any kind, even if there is a low percentage of wolf genes in the hybrid. States such as Indiana and Arkansas allow the ownership of hybrid animals, but they regulate it strictly with health records, immunization records, and registration of the animal, while other states, such as Arizona, do not have any laws about owning a wolfdog hybrid. States may or may not create their own laws regarding the issue of wolfdog hybrids. The Ethiopian wolf's conservation is threatened by dog hybridisation. Wolf hybrids Wolfdog hybrid The domestic dog (Canis familiaris) is a domesticated species of the gray wolf (Canis lupus), along with the dingo (Canis familiaris). Therefore, crosses between these species are biologically unremarkable and not a hybridization in the same sense as an interbreeding between different species of Canidae. Wolves are different from domestic dogs in that wolves usually have slimmer chests, longer legs, and they also have stronger jaws than those of the domestic dog subspecies. The difference in appearance from the wolf to the domestic dog becomes even larger when a mix of the two animals is created. Wolfdogs do not have one common description of their appearance because it varies from one breeding cycle to the next. It differs from cycle to cycle because the number of wolf genes inherited in the animal differs greatly and is recorded in a percentage form. The general layout for describing the percentage of wolfdogs is as follows: 1-49% is considered low content (LC), 50-74% is considered to be mid-content (MC), and 75% and higher is considered to be high content (HC). The percentage of the amount of wolf in a wolfdog decides what the animal will look like. For example, if a wolfdog is 25% husky and 75% wolf, it will appear more like a wolf than a husky because it contains more genes from the wolf. This means that the appearance of the wolfdog will most likely contain a narrower chest, longer legs, and sharper teeth because it inherited more traits from the wolf parent. People wanting to improve domestic dogs or create an exotic pet may breed domestic dogs to wolves. Gray wolves have been crossed with dogs that have a wolf-like appearance, such as German Shepherds to form the Czechoslovakian Wolfdog. The breeding of wolf–dog crosses is controversial, with opponents purporting that it produces an animal unfit
