@seac,
Dogs vary, including among dobermans.
My business partner's sister raised dobies, I think in alaska or close.
My business partner had two dobies (first I knew of them, different situations.)
The first dobie was one she rescued when he was thrown off a truck on a southern california highway. She pulled off, scraped him up, and paid for his hip replacement surgery and likely more. The dog loved her, not so much loving the rest of us, but no bad stuff happened.
More dobie stories later. Pacco's best friend was a doberman.
