I started training my pup when we still had my old girl, Abby.
training her alone proved that she was very unsure of water, but as soon as her old playfriend, Abby jumped in, she went right in after her.... no second thoughts - and that was when she was only a few months old.
be careful at first, no big water-stick with a small pond.
went puddler hunting this year as usual.... shot more divers than puddle ducks. typical
