Review on PetSpy P620B: Waterproof Dual Dog Training Shock Collar with Vibration, Electric Shock, Beep - Remote Trainer for 2 Dogs, 10-140 lbs by Teri Washington

So I recently adopted a lovely Britney mix from a crowded animal shelter. When I brought her home she ate anything with a white filling. chew it chew it Put it outside. Chew on the plants. Barking continuously until you let them back inside. Constantly jumping, biting and scratching. She is very playful, which is good. Just not always. I bought this product hoping to dampen the constant braking (out of respect for my neighbors) - Small note (although I don't recommend it if you're not as curious as I am): I've tried the collar on myself, before I put it on my puppy. I wanted to know how bad it would be before experimenting with different levels on my dog. The vibration is bearable and is just a reminder (hey, the collar is on, don't shock me). The highest shock I could take was 4. And it BITES lol. So I don't put my pup over 3. She senses this and makes a little "squeak". this hurts me a little inside. But it's all for a good cause. She's stopped barking at nothing, stopped jumping at me and my guests (still does, but not as much), stopped nibbling at everything. (I bought her many rows but she destroys them in a couple of hours! Haha). In general I am satisfied with this product. It takes persistence, but it works. Note: I just remembered moving the lawnmower from the backyard to the front. She ran away from the yard without a leash. Big no no in my area. I tried to follow her but she kept running and looking around thinking we were playing and the further she walked the more I worried that someone (nosy neighbors) would see her off leash outside. I called her back with a little "Zap" "Come here". She immediately stopped running and started listening to me. I was able to return it with no problems.
