Hi, I have a 3 yr. old newfoundland named Buddy.  Buddy was never in water as a puppy. Last summer I brought Buddy out to a lake house of a friend of mine and Buddy would only go into the water as far as he could stand. I tried getting him in the water from the dock and he wouldn't jump in. I tried pushing him in and then he runs away and won't allow that again.  I thought Newfoundlands instinctually love the water.  Does any one know what's the matter.  Maybe, it's something I did in training.  Or, does any one have training tips to get him in the water.
