Query: My Pups Just Didn't Get How To Use This Product

I was really hopeful about this product working. I have four dogs, ages 2 through 8. I tried and tried to teach them how to use this product, but they just never could make the connection of the bark to pushing the button. They just ignored the paw and wouldn't ever put their paw on it to even touch it.
