One study found that out of 106 captive wolfdogs tested, only 33% were found to be purebred. The remaining 67% were found to be either mixed with other dog breeds or had no wolf content at all. Another study found that out of 43 wolfdogs tested, only 21% were found to be purebred. The remaining 79% were found to be mixed with other dog breeds.
These studies suggest that a significant number of wolfdogs are not purebred. However, it is important to note that these studies were conducted on a limited number of wolfdogs, and the results may not be representative of the entire wolfdog population.
It is also important to note that there is no consensus on what defines a wolfdog. Some people believe that a wolfdog must have at least 50% wolf content in order to be considered a true wolfdog. Others believe that any dog with any amount of wolf content can be considered a wolfdog. This lack of consensus can make it difficult to accurately determine how many wolfdogs are fake.
Ultimately, the best way to determine if a wolfdog is fake is to have the dog tested by a reputable genetic testing laboratory. Genetic testing can accurately determine the percentage of wolf content in a dog's DNA.
