The listing, CLICKER for Dogs-- Training Aide. Barely Used. has ended.
CLICKER. Barely Used. Out of package, but in fine shape. Runs anywhere from $10-$20 with shipping.
All the info you could want is on the web for how to use the clicker as a training aide. The clicker itself has a website address on it and I may even be able to find the info that came with it. My dog just hates it, that's all. She's got sensitive ears.
From the Web search I did:"Based on operant and classical conditioning principles, clickers help speed learning by up to 50 percent. Ergonomic design with easy to find and press raised button. Stainless steel clicker element will not rust."
I'm offering free shipping to the USA because I'm hoping it wont be too much. It's very light and small-- fits in your pocket!
