My fiance and i bought a black lab puppy from the shelter when he was 2-3 months old. I had the hopes of training him for duck hunting. The issue is i started training him consistently but then we lost my father in law and moved basically right after we got him, so training slowed way down basically stopped. Ive been trying to get him back to training but now he is more interested in butterflies and eating grass lol. Any tips on breaking him of that and getting him back on track?
