I focus a lot on reading your dog’s arousal levels, to ensure that your dog A) is not becoming sensitized to stimuli in the environment and B) is able to behave and think and learn (a stressed brain — excitement or anxiety — doesn’t function well).
When you are working on helping your dog learn to self-regulate around triggers, reading your dog’s arousal level is essential. You want your dog to be under threshold. You allow your dog to approach the trigger (increase the intensity of the trigger) until your dog reaches the threshold distance (the smallest distance where your dog is still able to be “under threshold”). After spending a bit of time at that distance, you retreat from the trigger (lower the intensity of the trigger) and give your dog some recovery time. How much time do allow your dog to spend at the “threshold distance”? The answer is “just enough but not too much.” LOL And the answer will differ depend on your dog’s nervous system that day at that time in that situation. How much time do you allow your dog to spend at a low intensity distance for “recovery time?” The answer is “not too little” and you need to read your dog’s subtle body language and know your dog well to know if he/she needs more time for his/her nervous system to recover.
And remember that the last half of the class may be very different than the first half: your dog’s nervous system might be getting overloaded after 30 minutes of the class (or less for some dogs). We like to hope that the longer the exposure time, the more the dog will become used to it, but this isn’t always the case. The dog’s nervous system gets tired just like ours does after a long period of stress.
And we always want to err on the side of caution to avoid the opposite to our goal — we don’t want to SENSITIZE the dog to the trigger, which can easily happen if we are setting our hopes and expectations too high. This is often the case if we find that the dog doesn’t seem to be improving.
So, here’s a little tip:
When you are setting a goal, make the goal about your dog’s arousal level, not about the distance or duration.
What I mean is that if you are thinking “I’m going to see if my dog can pass by that trigger at distance X” then your focus is on “distance X” and you may be inadvertently setting your dog up to fail (or to become sensitized to the trigger). If you change your thinking to “I’m going to see if my dog can maintain an arousal level of 2 as we pass by that trigger” then your focus is on the dog’s arousal level. The distance your dog needed at that time will be noted by you for future encounters, but that distance is not the goal.
