Does that mean dogs that live with cats won't chase wildlife?
I WISH! Lol. No, unfortunately having a non-prey cat in the home, has nothing to do with it. Most dogs, especially if the animal is introduced when the dog is a puppy, will accept other family animals. But they usually don't generalize to outside cats or other animals.
My concern is ... not sure.... just want to think it thru since it involves my dog changing her perception about things. Before I just want her perception to be listening to whatever I say, so if I say no chase or abandon chase, she must comply. Your way, correct me freely if I'm stating it wrong, is teaching the dog to be fearful to chase.
I’m hereby correcting you. lol. If this was done at high levels of stim it WOULD create a fear of the chase and probably of the prey animal as well. Going back to the snake proofing model, there you want (and when it's done properly, you get) a dog that is AFRAID of the snake because he "bites" from a distance. But using low level stim the dogs don't become afraid of either the chase or the prey animal. In the snake model, you want the dog to RUN LIKE HECK from a snake. The cost of not doing so can be a slow agonizing death. In the crittering model you just want the dog not to start the chase.
Typically, the dogs see the prey animal and go right back to whatever they were doing. There's no avoidance with this system.
The method was developed to stop police dogs from chasing cats during yard-to-yard searches. If it resulted in the dogs fearing the cats, they might refuse to go into back yards where cat odor was present. In the urban environment, that's problaby just about every back yard out there. Either a cat lives there or has wandered through in the past several hours. WORSE, the dog might go into the back yard, and LOOK LIKE he was searching, fooling his handler and perhaps missing a crook that was hiding there, because he was so distracted by the chance of getting slammed by a shock.
