Training And Understanding Tips
Well a little understanding must first precede the answer. All male dogs have a propensity to establish dominance and fight for what they feel as theirs. That is their natural instinct and that is why it is so hard to come up with an answer to this question.
The easiest way to avoid this problem (if it isn't too late) is to start EARLY. Do not allow your Chesapeake to fight at an early age. Discourage it at all costs or in the future you will see the playful-like sparring of a puppy, turn into vicious tendencies as an adult.
For those of you who feel it is too late; the only "serious" advice I can offer is a type of associative training. In psychology, "shrinks" often cure phobias by associating the phobia with a positive environment or object; sometimes both.
My advice to you is to place your dog in an environment with few distractions and borrow a male dog from someone you know. Keep the dogs separated until you are ready to begin a simple training exercise. It can consist of any commands that the dog is trained to obey. The object here is to associate obeying and following commands while at the same time having a strange dog in the same room. This process changes the dog's train of thought to include another strange animal as part of its obedience training.
Some breeders I know disagree with my methods but are amazed by my results. Their methods are much easier but I feel my ways are better for the dogs. Choosing to neuter and lash a dog for its predisposition is wrong as I see it. If you care for your pet I would suggest trying it my way before you look into neutering your pet to correct aggression.
When they have holding down, move to step two. While the dog is holding the stick, give a command that consists of some words telling the dog to place the stick in a pile. Then imediately walk with the dog over to the pile and make yet another command for the dog to drop the stick. If it seems that I am being vague on how exactly to do this, it's because I don't want to tell you how to creatively do this. This is more of a trick than a useful command. Some dogs play basketball, maybe yours can learn to pick up sticks.
