SeaSense Eco-Blast Refillable Air Horn

Great, love that its refillable. Hate we already have so much waste. And works great.

I used this as a training tool to teach my dog to stop barking for no reason, she would be in the back yard barking and barking at nothing. I would open back door, give the air horn a blast and she would immediately stop barking and come onto back porch to see what the noise was, of course I had already gone back inside the house.. If she barked again, I simply repeated the procedure and after a couple of days, maybe using the air horn a dozen time or more, she stopped barking when she was outside. NOTE, When she was in the house, she would still alert to sounds she heard outside, so it did not keep her from being a great watch dog. Worked on my son's two dogs also. We never used the air horn when our dogs were close by only when they were out of site and barking in our back yards. Did not want to damage their hearing, air horn is very loud. Great training tool.
