## Questions & Answers

**Q: Mine didn’t come with a battery**
A: They don’t come with batteries.

**Q: Does it hurt the dog?**
A: No, not my knowledge. It works on small dog. It didn’t really work for large dogs.

**Q: Can this be used to train cat behavior?**
A: I don't think cats hear the high frequency noise that this emits - so I would say no. 
Cats are usually able to be trained the best with treats.

**Q: My new dogs barks when i crate her to go to work, disturbing neighbors.  can i set this unit to emit a sound to stop my dog from barking when i leave?**
A: Yes you can. It works perfectly and after doing it a few times, your dog will know what is coming if he barks. Just show him your hand. That will do it. I used to 
have the same problem all the time even inside the house. NOT ANYMORE.

### ⭐⭐⭐⭐⭐ Review
*by L***E on 10 December 2021*

Bien sûr, le mode le plus puissant est à n'utiliser qu'en cas de besoin, mais le mode le moins puissant permet d'éduquer le chien à la manière d'un clicker, où de le "saisir" lorsqu'il fait une bêtise et n'écoute pas, par ex. Personnellement, j'ai du acheter cet appareil parce que j'ai eut des problème avec un voisin qui trouvait ma chienne trop bruyante. Je regrette néanmoins de ne pas avoir découvert ce genre d'appareil plus tôt car ma chienne, très gentille, était en revanche difficile à éduquer. Petite information supplémentaire mais néant pas à voir quelque chose avec les chiens : l'appareil effraye les rats. J'ai réussi à en chasser des qui venait de chez un autre voisin grâce à cet appareil.
