Hey whats going on everyone. I am new to waterfowl hunting with a dog. Ive got a 2 year old choclate.That Ive put alot of time into and this will be his first year to hunt. Our season in arkansas opens the 19 of nov.. This may sound like a dumb question. BUt i dont know the answer so iam going to ask. How do u know when the dog is to cold. I mean i know they shake after they come out of cold water. But is there any tell tell signs that should let me know when enough is enough? Anything helps thanks
