Rescue organizations consider any dog with wolf heritage within the last five generations to be a wolfdog, including some established wolfdog breeds.1
Because DNA testing has not advanced far enough to be able to truly make an appropriate distinction between wolf and dog DNA, wolfdogs are categorized by phenotype—the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.2 In other words, the amount of wolf characteristics they express genetically both physically and behaviorally.
There are three main categories: High Content, Mid Content, and Low Content.
High Content: The wolfdog expresses mostly wolf characteristics physically and behaviorally.
Mid Content: The wolfdog expresses both wolf and dog characteristics.
Low Content: The wolfdog expresses mostly dog characteristics physically and behaviorally.
And of course, a wolfdog can fall anywhere in-between any of these categories.
