Putting Chuck It ball next to “Spot” caused some distraction. Additionally, excitement level. However, her enthusiasm is excellent. I would not want to punish this, normally, her response to “Spot” is good. It was my mistake. Should have realized chuck it balls sink, so not good choice for retention pond when full of water. Dog training often requires us to pay attention to fine lines IF we want to avoid using punishers that could have negative effects on training and relationship.
