i walk the lab and isis at the same time one on hand and one on the other, the lab seem to have a major drive to sniff out anything and track blindly and of course isis will be doing the same, the b is easier to control cause she lighter but the m1 tank of the lab well.. we've came across little furry friends on our nitely walks i need to stay very focus on my surroundings, one thing the b does if theres someone walking behind us doesnt matter how far , she walk ahead stop and turn to look back, she'll keep doing this repeatedly like she warning me these something there,im sure its instinct on her end to,of course i confirm whats shes doing but yeah those b's dont miss a trick
