Designed specifically for tougher, more stubborn dogs, the 425S has a higher range of stimulation than the SD-425. The 425 series is ideal for training in the yard, field, or for hunting with close-working dogs. Switch instantly between stimulation, vibration, and tone to fit the correction or communication to your dog’s temperament and learning ability.

had it for about four months and changed the way me and my gsp work together,the only down fall is two days before our first grouse hunt, the transmitter seems to be only working at very close range, hope it's just the battery, anyhow bought the 1225 for the hunt, hope that it stands up to the sportdog promise, more to come on the 1225.

SPORTDOG RESPONSE: We're sorry to hear that you are experiencing trouble with your SD-425S. We do offer a warranty on our 425 that would prevent you from having to purchase a new system. The SD-1225 does offer a much bigger range than the SD-425S, but we also offer batteries through our Customer Care Center and almost all of our e-collars offer user replacement batteries.

pitbull/blacklab mix. stubborn and don't listen. Now she comes after I call her.
My dog loves her collar. She knows the collar means no pen. Pitbull/black lab very stubborn. With training I never have to use more the a vibration. I love it because I don't have to use the stimulation anymore the vibration is enough

Great training tool!
I just purchased the 425S for my 14 mo Dutch Shepherd. While he understood the obedience commands, he would push it to the limits before he would listen. He would bolt after deer and not come back on command, constantly be on our older Lab to the point where we would have to separate them. Our relationship was becoming frustrating to say the least. We had great results after only a few hours of placing the receiver on our dog. And now after only a few days he seems calmer, more obedient, and willing to please. My only issue/question is that a few times after unit has been fully charged I find that the transmitter does not seem to be working. I plugged it back in and then after approx 10 mins will try again and it works. Can I get some feedback from other users or customer relations?

SPORTDOG RESPONSE: Glad to hear you are enjoying the system. It's possible you have a minor adapter issue. Give us a call at 800.732.0144 and we can get your set up with a new one.
