This product with a full charged battery did not work on my 2 month Dotson puppy. I tried almost everything from close up placement to long range placement. All three levels of sound and nothing not sure if it was my type of dog or her age but turns out a shock collar worked better then this product. Who knows might of been a bad product I’ll never know.
