Mara5-Short answer is because thats the kind of dogs we own and dont want to leave any dogs at truck. Its amusing how fast the labs figured out what it means when mine go on point. Its not ideal but works for us, we hunt exclusivly public land in SD and end up separated by a draw or 100 yds a lot to. I hunt a lot more than my son but every sat and many Sundays this is how weve always done it,
