You gotto love them labs, when I dog sit my moms pom, Tasha likes to NOSE her, thats down in the puppy stance,cocks her head back and then rams her with her nose, she can roll her over with a good NOSING, Tasha= 67 lbs, Pom=8 lbs she does this till she provokes an attack, then jumps up, spins around and presents the Pom her rear end Having six pent up labs made for some excitement
