I would actually have to see behavior to tell you anything. As for the wisdom panels, or DNA tests, they are still inconclusive. The clinic my wife works for had some known dogs tested, they came back with mixed results. One dog said something like 70% inconclusive, another dog that was a purebred came back as a mix. These were recent tests. I don't know if they were cheek swab tests or blood. That may make a difference but I doubt it.
I can tell you one thing, mixed breeds more often than not get the best aspecs of what ever breeds they have in them. I have a thirteen year old mix that is still going strong, he has never been to the vet for anything health related. He has gotten punctured by stuff but that was him having fun. He has the teeth of a 3 year old. Hybrid vigor is good stuff.
