This is one fast dog, she was the fastest dog in her litter, great althlete, good size. At 10 weeks she was outrunning me, then outrunning me on bike, then outrunning Alonso and I on bike. At 5 months Peppah was so fast I harnessed her because she was running too far ahead, she started pulling hard right away. She never seems to get tired She runs best in double lead, My idea of the perfect size female for a 6 to open dog team, I plan on using her as my main leader in the big races Laconia, canam 30, ect....
