Review on Waterproof and Rechargeable SportDOG Brand FieldTrainer 425X/SportHunter 825 Add-A-Dog Collar with Tone, Vibration, and Static - Ideal for Replacement or Additional Remote Trainer Collar by Rebecca Porter

LOVE this. The moment I put them on they both (one kind of sluggish Great Pier, one kind of dominant York) perfectly understand who the alpha is. MBA! Mr. Bossy, in Yorkie pants, especially twitches when the horn blares around town. If I need more than a beep on Mr. Bossy's pants, it doesn't take long. It only weighs 12 pounds so a beep or shock setting of 1 usually makes it look like IB$! Tuesday. My Pyr has a lot of fluff on his neck and went to 5 to get her off the road and got a squeak from it. **Please note she ignored the beep, shock levels 1, 2, 3 and 4***. Overall I think this is a great quality piece of exercise equipment that I am very happy with. Reloads quickly. Don't forget to turn your devices back on after charging. They turn off automatically and need to be turned on again. Sorry the neighbor who lost her panties because Lola Great Feast, she looks like a polar bear, is slowly walking towards your chihuahua. She wasn't hungry. Promise. Lesson learned. Haven't tried them underwater yet, but they performed well in the rain. DO THAT!
