My dog likes to bark loudly when he can't see me when I am sleeping at night.I often make noise with my neighbors, and they often come to complain to me.I had to buy this barker, and it seems to be working. My dog doesn't make so much noise at night.

works better than expected!

The effect is very good

This product really works!

Fits ok. Little bulky for my chiweenie But all in all it works great.

I love how my dogs instantly stopped barking ! It’s such a relief to let them be in the yard and go inside your house and finally be calm. I love these!
