RE: new lab pup
Personaly I'd wait until the spring now and warmer temperatures. Just don the waders and get in there with your youngsters. Two problems in a dog this young. One is a pup as young as this has a harder time regulateing body temp as an pup that's somewhat older. Second such early exposure to such cold water at this age can help bring on premature arthritus. Better to wait . There is plenty you can do with a young dog. Might I suggest "Training Your Retiever " by James Lamb Free
