Love it!!!
We have had the 425s for almost a year now, and we love it. We have had a few warranty issues but they were taken care of quickly and without a problem. I couldn't ask for a better customer service/warranty team, that is very hard to find these days. Thanks Sport Dog for your great products.

7yr pit. well broke, but wife has cats!
Recently got the collar to help ease her into a cats home, after the initial chase after the cat, w her first level 7 stimulation it STOPPED her in her tracks! She turned right around to come back to me. Also helps keep outta neighboring yards, even though she don't go on the road still gives me rest to know if another animal takes off and she chases w a car coming that I can stop her if I have the chance. she likes to play at the creek DOES ANYONE KNOW HOW LONG THE COLLAR CAN TAKE ON WATER, HOW LONG IT CAN SAFELY B SUBMERGED? ALSO DOES WARRENTY COVER WATER DAMAGE? DOES MOD:SDT00-13857 HAVE A BATTERY PACK ONLY OR CAN IT USE JUST BATTERIES?

SPORTODG RESPONSE: This system is fully submersible in water up to 25 feet. You will have absolutely no problem with the dog being in water for any length of time. We have a battery pack for it.

Great Product!
My boyfriend and I bought this for our 1.5 year old black lab. He is very food motivated so when we worked with food he was very easy to train. When we let him outside, it was a completely different story. He would run away and think it was a game so we would need to chase him or risk him becoming injured. He is also very stubborn and has a mind of his own at times. Let me tell you, half a year later and almost a daily use, he is a completely different dog. We wake up, and he knows he gets the collar and he is able to go outside and run free. He wags his tail as soon as he sees it. He loves to be free especially when we go to family events where other dogs are able to run free and he can now join instead of us fearing the worst and keeping him on a leash. We recently got another lab puppy and instead of trying to beat around the bushes again, we bought an add a dog collar so she can also run free. We haven't used it yet, since she is not old enough yet, but we have high expectations. It is truly a great investment and I would recommend sport dog products to anyone and everyone. Don't believe anyone when they say that the collar can hurt your dog. If you watch the video and read the basic training book before you put the collar on your dog, you'll know how to use the collar, and things to avoid.
