sounds like a great dog... my lab spoiled me for the last 11 years. couldn't ask for a better canine companion, and
brother that dog lived to hunt!!!
imo, browntop millet is the best grass planting for waterfowl. i think it produces more seed per plant than jap. millet in ideal conditions (i.e. water-controlled marsh). i've heard that jap millet is more resilient than b.t. if summer t-storms cause temporary flooding (such as a pond). i disagree and think both tolerate brief flooding well.
good luck and scratch your dogs ears for me.
