I've looked into this too. Like you, I've been hesitant to spend the money without knowing what kind of results I'm going to get. Jersey is a rescue...sorta. More like the offspring of a rescue. Her momma' was a Beagle a good samaritan found as a very pregnant stray on the side of the road. So obviously, we don't know what daddy was. I've always wanted to know what else was in there. It won't matter. She's still my baby, but I'd still love to know.
