I sometimes take my young dog out with me hacking. She’s on a lead rope so perfectly legal. As a young pup lady frightened herself with a river so has been understandably not keen. She jumped in after our other dog and didn’t realise the depth. Saturday I tried again with a river crossing. Gave her time and could have used the bridge if needed. She took it slowly, plucked up her courage , and she did it. Kansas, pony, was as good as gold, reverse gear in a river, certainly mum. One very wet dog but I was so chuffed with them both.
