My two do the exact sme thing, specialy Apollo, realy embarrassing, i know..Apollo scared the h%$# out of me a few days ago, a lab was loose and we where walking, Apollo jerked so hard he snapped his 29 pound flexi leash in half, i realy thought he was a goner, he was nipping at that Labs hind legs before i was able to pick him up, thank god that dog must of been good natured as he only snapped at him and went the other way...my knees where shaking for hrs after that...mine love playing with my daughters half lab...they only do this when we are walking
