Hi,

Depends on the breed of dog and if they can move around or need to be still.

I've seen big Chessies that weren't happy until they could be swimming in sub-zero weather. On the other hand, my Springers are done duck hunting for me when the temps drop into the low to mid 30F's. But a dip in the water at zero doesn't bother them in the least if they can run to keep warm.

So it really depends. But my rule is if I'm concerned about it, the dogs stay home. And if I do take them out, I watch them and I take note of how they are preforming and feeling. I have no trouble ending a hunt because my dogs come first.
