Took my pup, Mickey, 23 weeks old to the water today with my other fellows. He went right in with them. Then I threw a mark no problems! So I was concerned about him not being in water early on his training that he would be a slow start, but not so. There was any evidence of puppy swimming. Just went in retrieved the bumper and swam back like he had done it all along! I was amazed and pleased. I will post a pic tomorrow.
