I actually saw this on TV a long time ago. I thought they were training a drug sniffing dog. I can't remember right now but I remember they threw a ball right into this big barrel of bottles and cans in this dog just drove right in! It was pretty funny. I didn't catch what you threw into the pool. Was it a ball?Our trainer told me to do this exercise. I guess to desensitize ? Not really sure of the purpose but I've seen other IPO / Ring Sport puppies do it
