Motivul pentru care câinii Chihuahua sunt mici, dar curajoși. Legătura neobișnuită cu coioții sălbatici (Studiu)

A recent genetic study reveals that Chihuahuas are partially related to wild coyotes, with coyote genes present in their ancestry. This small dog breed, originating from Mexico, exhibits traits similar to coyotes, such as territorial behavior. The study also highlights a mutation in the IGF1 gene that contributes to the small size of Chihuahuas and other small dog breeds. Researchers are unsure when coyote genes entered the Chihuahua lineage, but the findings may change how owners perceive their pets, likening them more to coyotes than wolves.
