I'm more worried about some of the people I run into.
I never took my dog fishing with me because he wasn't trained for that. I was concerned that he would run up to fisherman and disturb the water where they were fishing people.
I have encountered many well trained dogs while out fishing, and have never had any kind of an incident.
Back to the original purpose of the thread, I think it is wonderful to train your dog to go fishing with you. My dog passed away a couple of months ago. When I am ready for a new one, I am going to train him to come fishing with me.
All of the tips and tricks are much appreciated.
