Nothing Dog just lays there. Not even a twitch.
Not the best! Worked for a little while then started staying on and now no sound at all.
I I didn't think it would work but oh my god it really does work my dog listens actually
It does not work I tried it on my dogs it didn't work
Helped my dogs from barking at every little noise.
It doesnt wanna install!!!! It just says ERROR on installing this app
