My trade magazine has published a journalistic review of three Dog DNA tests. You may find this video report helpful and interesting. C&EN tested one dog’s genetics and got weird results
That's how Bat-dog is. Her nose is in charge. Yes, she's part beagle. But she's also part chow and that adds an overabundance of stubbornness to her.
A friend found out the hard way that dogs hold grudges (a scientific study recently showed this). When she first met Bat-dog, Bat-dog barked at her. So she barked back - it was not acceptable behavior. Bat-dog held that grudge for over 5 years. It took a LOT of back scratching for Bat-dog to forgive her.
