I own 2 German Shepherds. 1 that's 2 years of age, and another that is 8 months. I just recently spent a lot of money landscaping the yard and I planted flowers where the puppy enjoyed digging on the regular. I just got this yesterday, and she already will NOT go near her digging spot. Yes! I will be getting another one of these rocks for when I start my vegetable garden! I'm very very very satisfied with this product and would absolutely recommend it!
The only problem I ran into was she went into the range of where she shouldn't have been, I heard the collar beeping, but she wasn't reacting. So I looked in the book that was sent with the rock/collar, and it said that the hair could be blocking the skin so the collar doesn't give the slight shock. So I trimmed the hair on her neck and problem solved. No she does not have a patch of missing hair, lol you really can't tell I even trimmed it.
Thank you PetSafe for this great product!
