I would not recommend. The dog needs to understand "NO" command. This hissing sound does nothing for extremely well socialised dogs (aka healthy dogs). My dogs are all well exposed to all kinds of sounds including crackers sounds and they are very calm throughout. I have used this product and no good came out of it. After that we got a dog trainer who literally made us under go a few trainings with our dogs to establish boundary and now even if we sit next to the dog and eat the dog does not bother us or does not steal food or does not cross the kitchen boundary.
Don't try to traumatize your dog by using all this hissing sounds.
