The big problem with hybrids is that as puppies, they act extremely similar to dogs. It's impossible to tell whether or not they have inherited the wolf temperament. But when they reach maturity at 1-2 years of age, their adult wolflike temperaments set in. That's when they can become extremely dominant, stranger-shy, aggressive towards other dogs, and get an extremely high prey drive.
In this case, the dog looks like it's already fully adult. Even if it is (although I really doubt it) a hybrid, it's unlikely that its temperament will change at this age. It would still make a great pet.
