FieldTrainer 425S Stubborn Dog Model

The FieldTrainer® 425S takes the most advanced, industry-leading technology that SportDOG™ Brand has ever built into its e-collars and packaged it up in the most compact system ever offered. 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. This new 425S Model is an upgraded replacement for the FieldTrainer 400S.

best tool ever
I made this purchase after my son had a hunting dog and I saw how perfectly the dog listened with the aid of this collar. I have since purchased two(1 replaced for lost collar) and plan on getting two more in about 1week! I want to add onto the sd425s for our 3 dogs. I wish the newest collar was more affordable for dogs that like to run around the neighborhood just so they would be easier to find! Btw our Dobie is a perfect gentledog thanks to his manners being "reminded about" by wearing this collar, the golden and min pin are next to have their manners improved!

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
