Attack dog training

Interesting walk today....spotted this bloke teaching his dog to attack him while he was in the water. 2 people were filming this as again and again this very well trained and very large dog dived into the water avoided the stick and sank its teeth into the blokes arm. Bloke had full body kit on to protect him .... not what you expect to see when out for a stroll with your daughter and your dogs..... and of course my answer to my 4 year old daughter was "the man is playing fetch with the stick to teach his dog to swim"....... small lie but she loves animals and that distracted her so back to finding shells again......
