What can I say about this collar? That it works, miracles.
It's one piece, instead of a box that hangs off of a regular nylon collar, ensuring contact. It also has a right fit test to make sure it's doing it's job. It's waterproof, even allowing the dog to swim with it on. No, on/off buttons on the collar itself, it turns on/off like a tv remote. Using the remote, which comes with a lanyard, you can be far from your dog, which is let's face it, when they tend to misbehave anyway.
There is 9 levels, and a boost that let's you up it by 2 for that moment. There is also a timeout safety feature in case you hold the button down for 10 seconds or longer. The best part is the tone button. The manual says you can use it for a reward or warning, just not the two. That would just confuse Fido. My dog learned quickly that the tone means a warning. That way, if I press that button, she acknowledges it, and stops the behavior straight away. This also means there's no correction after awhile, since the dog learns what comes after the tone. Unless you use it for a reward sound. Then I guess it's more like clicker training.
So, why is it the new religious collar?
Because it makes a believer out of the dog. And, since the dog sees the behavior as getting a correction, and not you giving it, it seems to make training quicker. Because of course you don't want your dog afraid of you.
Now, I know there are people who think it's inhumane to use a collar like this. Personally we tried the citronella collar, and I wish I'd saved my money. It didn't do squat for our Doberman. I think this collar is more humane than having a dog put down, which is exactly what people do when they find they can't handle their unruly, aggressive dogs.
