I had seen the Bark Off advertised on TV and though it would be perfect for our German Shepherd mix dog, who barks everytime my husband takes the kids to the bus stop, or she sees the neighbor's dog through the window. We have a six month old baby and every single morning the barking wakes her up. I purchased the** Bark Off **at Bed Bath and Beyond. The sales associate there told me that her manager had great results using the Bark Off with her dog. I was cautiously optimistic. I started out with it on the low volume as we also have a puppy and I didn't want to hurt his ears. Our dog continued to bark. I turned it up to the high setting and it still did not effect her. We have a picture of her standing right next to the **Bark Off **and barking her head off! I would not recommend this product to anyone, and I will be returning ours to the store as soon as I can find the receipt. So save yourself some money and go for a real bark collar.
