Are you looking to work the dog in a sport? If you bring the dog to the local shutzhund club they will be able to tell more than us. Once you have the dog the lines are kinda irrelevant, you have what you have. I have a czech bitch, her dad is mutz aritar bastet and mom is capri vom Izeneherzt SP.
She loves every person and dog shes ever met, not quite up to standard
Shes just what I wanted and raised her to be so lines dont decide everything.
