## Questions & Answers

**Q: It's not working**
A: My dog passed away last month but the product did not help control the barking. It could be as she was an elderly / senior citizen and the hearing was depleted.

**Q: how close do you need to be to the dog? Thinking Street dogs**
A: This product is a waste. I tried it multiple times, but instead of scaring the dogs, they were trying to attack me. Used all the options. now its lying somewhere as an e-waste
