She has actually been doing better with mouthing since we moved to a house in a less urban, dog dense neighborhood with a bigger yard for her to burn off energy, and since we got her a brother to appropriately play with using her mouth. She hasn't mouthed on a walk in a month. Last night she did, but it was because it had been her long day in her crate, she hadn't been out all day, and she didn't want to come in from playing with her brother and instead of putting a leash on or enticing her with her ball I tried to pull her in by her collar. Handler mistake. The local IPO club is two hours away... We joined the German shepherd dog club, but there were too many dogs in the class for her and she just wasn't over her hand shyness enough yet to be able to participate. Also, they used leash corrections and prongs combined with treats. She just couldn't focus. At the class I brought her to at the humane society ( it was a one time recall class) they used clickers and there were fewer dogs to distract her and she LOVED it, did great, was able to focus because of the clicker. They do have agility at the club and I think eventually she might be ready to take some classes there but right now she focuses best with the clicker in my opinion. Thank you for the advice, you are echoing what my husband sometimes says. It drove him nuts when we had a positive only behaviorist come over to help us with the hand shyness and mouthing because he believed that the type of dog she is requires more stern training. Our breeder uses positive training with her dogs and doesn't seem to approve of prongs, so I think it is possible to train this type of dog positively. She trains and titles her dogs in SAR, schutzhund, flyball, etc.
