User questions & answers

Question:	Will this ever damage their ears
Answer:	I asked my vet. She said no residual damage—but I think it’s more like hearing a weird STARTLING sound. It startled my dog and all of a sudden she stopped barking and looked at me. I literally barely have used the ultrasonic buttons bc if you use it a few tunes, your dog will hear the (audible) sound and it’ll remind them of the other sound... my dog heard great... seriously, I urge you to try this! (I wouldn’t show you in a video though because my dog hasn’t been barking)
Question:	What’s the whistle for
Answer:	The whistle is for if your training your dog it lets out a noise only they can hear
Question:	do you have to point this device toward the dog? do they feel anything or it emits some sound? can this also be used to stop bitting
Answer:	No you do not point it. You can not hear it. I think it hurts their ears. Yes I think it would help with biting. I bought this and used 2 times for barking and jumping. They stopped immediately. My Yorkie is so smart, he got up on the desk and chewed it up that night! I ordered a new one and keep it on top of the fridge, they respond to NO a whole lot better. I have had to use it a few more times.
Question:	what is the seonc piece, the long skinny item on a lanyard for
Answer:	It looks like a dog whistle, but I didn't get that piece. Wish I did.
