GRRRRRRR!
Stupid app! Believe me when I say, your dogs will hear it and then ten seconds later run off crying. My two dogs are filled with energy and love to play, unfortunately when ever they are playing they break everything in sight. I thought I could use this to break them up sometimes. All it did was give me a headache and send them off whimpering! I do not recommend this app
