It comes with 7 instantly selectable stimulation levels and can be expanded up to 3 dogs by simply adding SportDog Brand Add-A-Dog collars.

E-collar Training Support

Manufacturers include owner’s manuals with their products but most do NOT provide any type of training material on how to properly use an e-collar to teach basic commands and resolving behavioral issues. Our competitors offer you nothing as well as most are in it only for the money and don’t know the first thing about e-collar training. Many won’t even be able to tell you how to turn one on.

We’ve been around since 2003 and train dogs with e-collars every day. We’re true-blue dog lovers and it’s extremely important to us that these training tools are used safely and responsibly. To make sure that you achieve the desired results that you are looking for in training your dog, we’ve taken it to the next level and offer you unparalleled support that you won’t find when purchasing from a competitor or directly from a manufacturer.

Beware of Unauthorized Resellers

It is important that you purchase from an “Authorized Dealer". Why? Because you will lose your warranty if you don’t. Be wary of prices out there that are lower than everyone else's. If it looks too good to be true, then it probably is! All the top manufactures enforce Minimum Advertised Pricing (MAP), which means if you see the same model on another site at a lower price, they are probably not an authorized dealer and/or a scam site.

K9electronics has been in business since 2003 and is an "Authorized Dealer" for all the brands we carry so you can feel safe and confident when you purchase with us, but don’t take our word for it. We recommend that you contact any of our manufacturers directly and ask them about us.

K9electronics.com vs Brick & Mortar Stores

While many people do their research online,sometimes they feel more comfortable purchasing from a local pet store, but the best quality dog training collars at the lowest prices can only be purchased online. Most of the brick & mortar stores are huge chains that carry low end brands at a high end prices.

The large chain pet stores have a high return rate due to high employee turn-over. Typically, the big chains employ inexperienced workers who may mean well, but often give wrong advice and/or collar recommendations which lead to inappropriate purchases and perpetuate misunderstandings about remote trainers in general.

  The perfect training collar!

Sep 15, 2014

Reviewed By James
From THE U.S. of A.


I purchased this collar to help with training my (somewhat stubborn) Male neutered German, German Shepherd (14 months old).
What you read in the description is everything you're expecting and more. The quality is superb.

The one thing I did have to add, is the customer service is top notch. Had a little issue with an item I ordered and wasn't in stock, and they promptly called me to apologize and tell me I had been refunded.

Also, I was talking about how I got scammed by another vendor where I purchased a "Pet Safe" collar unit which actually it wasn't made by Pet Safe. I contacted the Pet Safe company and they cleared up the fact the model was not one they manufacture. That is probably why it didn't work.

The Gentleman I spoke with was very informative, and had actually heard of someone with the same issue. SO BE CAREFUL TO MAKE SURE YOU ARE GETTING AUTHENTIC GEAR!!

You won't be scammed by K9 Electronics, and no I don't work for them, I'm just a very satisfied customer. Hope this review helps.

High Quality, Durable, works great for what you need it for.
Transmitter and buttons are all black and numbers on the intensity knob are discreet, if your vision is fine, you'll have no problem. I did though have to show my not so old mother, where the buttons were, so if your near sighted vision isn't so great, you'll kind of have to learn where the buttons are by feel. Not a big problem but buttons could be of contrast color.

  SportDOG SD-425S

Feb 19, 2014

From Toronto, Canada


Purchased the SportDOG SD-425S (Stubborn) for my malinois cross G-sheppard because of his dog aggressive behaviour.

The product works wonders. My dog is under control and he actually listens and come when I say so.

The sales person truly knew what he was talking about in our online chat.

Definitely recommend this product for anyone with a stubborn dog.

Small, easily fits into your pocket, nice to the touch (smooth), rechargeability of the transmitter and the receiver, fits nicely on the dog's neck, charges quickly, well-built, good price for what it could do etc
Could have have had a belt-clip

  Excellent Collar

Sep 17, 2013

Reviewed By Maci's owner
From Lancaster County, PA


I really appreciate this product. I turned the settings down to medium and never need to turn the dial up past 2. My dog listens and even licks people she used to growl at. When we encounter another dog or jogger, we just have her sit and distract her. However, if the dog is getting in her space, we just give her short little zaps to keep her attention on us.
