Title: This item dos not work
Review: We read all the reviews and had high hopes for this item working for us...it didn't. We have a 7 month old Standard Poodle...maybe he has too much hair in his ears but it did not work for him. It also didn't work on the Shelties that bark their heads off next door. Thinking everyone that gave this item good reviews had a postage stamp sized backyard, only way it would work on your neighbors dogs. I would not recommend this item for outside at all. It did help in the house if you were only a couple feet from him, but otherwise, no go.
Is the review positive or negative?
