I'm thinking they are Siberian x German Shepherd, or they could be Alaskan Huskies (sled dog mutts bred for speed or endurance). Since they are both rescues, it's hard to say, but there's definitely more than just Sibe in there - they are taller and heavier than pure Sibes, with less of a coat.
Aww, they are both stunning. I love Bandit's face. Upendi's about the size of a husky and we were told she was huskyxcollie, but as she grew it became clear that wasn't the case. So we now believe she's huskyxgsd.
