Sturdy, reliable, and great for the dog park!
I recently purchased the Sports Dog Collar, and it has been great. The collar is sturdy and especially valuable at the dog park. I only use the sound and vibration options, and my dog responds immediately with no training required. At the park, this has been a game-changer. When my dog starts to run towards a skirmish or potential fight, a. press of the sound button brings her running back to me. This alone makes it worth the price! The only downside is that there is no way to know when the power is running low. I have to remember to charge it regularly. Another issue I had with the first collar was that it stopped working. When I noticed that my dog wasn't responding, I tested it on myself and it wasn't functioning. However, the company's customer service was excellent...I spoke with a very helpful representative who walked me through troubleshooting. When it was clear that the unit had failed, she quickly arranged to send me a brand new set. The replacement works perfectly, and I appreciate the responsiveness and support of their customer service.

Great for corrective action
We've had similar collars for our dogs before. I really like the push button instead of having to touch the remote to turn it on and off. The barking correction I wanted to instill on our younger female boxer was immediately corrected as she has previously worn one of these. All I had to do was use the beep once. These have a bite for the shock if you don't believe it, stick it to your neck and hit the button. I suggest doing it on one. The unit is quite robust so I don't imagine you will have any problems with durability.

Still working years later
Edit: I've been using this for years now after going back to it since all the other ones aren't actually waterproof. This is a quality collar and the knows loosened up after many uses. It's being used on a fairly small dog but a very very stubborn one and this collar is the intensity I needed to keep her safe off leash. It was worth the cost afterall. It took me awhile to write a review but after using this collar for over a month now I am so disappointed I spent the ridiculous amount this collar cost. I guess I should have researched more the remote is low quality abd has a turn nob to change settings and doesn't let you know which button you're pushing unlike most other collars abd the knob is super hard to move. Also if you are using vibrate mode it is only 1 strength which is very low almost pointless. I went back to my 30$ one

Great Quality!
Absolutely a great e collar and great customer service. Everything about this e collar is quality from the adjustable collar to the receiver and transmitter. I had an issue with the first collar I bought in that it would not charge after about 4 months. I contacted the company’s customer support and the service could not have been better. I received a free replacement collar in about 3 or 4 days. I highly recommend this collar and the manufacturer.

DON'T BUY THIS. JUNK OR DEFECTIVE
Do NOT buy this unit. UPDATED DEC 15 2021 USA. I added the longer electrodes and they didn’t make any difference. The sportdog continues to UNDERPERFORM. Right now I have no idea what power setting is activaged. I thought it was set on #2 but the test put my puppy on the ceiling. This unit may have a short. Nethertheless it’s a POS. This a review of the SPORT DOG E-trainer Model 425x, an electrical training collar designed for training animals, mainly dogs. This was purchased by me shortly after I adopted (purchased) my new 10 week old German Sheppard puppy with true blue bloodline documented by the AKC. The collar was purchased April 3, 2021 and put into use May 2021. The electrodes were 3/8. Extended 5/8 inch is a $10 option but back ordered 2 months+. I never write a review when I’m mad, and finally after several months using the SmartDog 425X I decided to write the review mad or not. Notes: 1) The extended electrodes are backordered 2 months…. Why? • 500 yard range e collar that can support training 3 dogs with the same remote with purchase of additional collars (SDR AF) • Choose to train with vibration (buzz), tone (beep), or 21 levels of static simulation in either momentary (nick) or continuous • Waterproof and submersible to 25 feet using DryTek technology • Lithium ion, rechargeable batteries feature a 2 hour quick charge, and a low battery indicator lets you know when to charge • Fits dogs 8 pounds or larger with neck sizes 5 to 22 inches • Age range description: All stages • Included components: Basic training manual • The puppy, is an energetic male of 10 lbs as a puppy, and is still growing at 11 months and approximate 80 lbs. His dog mom (130 lbs estimated and dog dad 150 lbs. Due to breeder issues Yeti was not transferred to me until he was 12+ weeks old. That is on the further edge of the training age and to wait longer will make training more difficult. He is a smart dog and I enrolled him a reputable boot camp for 2 weeks. He came home with a good attitude. We have a lot of distractions (cats, snakes, horses, coyotes, wolves, cougars, etc. on a 10 acre ranch with a stocked lake and I was afraid that we may have issues with him chasing animals or cars. The additional benefits of the SmartDog is to further train him with obedience for his and my safety. However, it seems NOT TO WORK about 80% of the time. Perhaps there’s a Broken wire which may cause the malfunctions, or maybe a design issue. The Good: Customer Service is very friendly and cooperative. I’d give them 5 stars. 2) The competitor’s devices are backorders 2 months .. that may indicate problems with this product forcing a purchase of the competition? The Bad: The E-Collar 425X is not reliable. My German Sheppard Puppy has thick hair so to get a electrical shock the collar has to be very tight making it hard to put a finger between the electrode and skin. The longer electrodes are ½ inch longer, but BACK ORDERED 2 months. Why? The Amazon advertising did not mention anything about dog size, fur thickness, etc. This may have affected the purchase decision. The color of controller is battleship gray which is hard to see at night or low light. I see adds for the orange version but not listed in the options on the Amazon pages. I put on orange tape to increase the visibility. I painted the control buttons but the paint came off after a few days. The controller is very small but then I have large hands (large gloves are very tight). I didn’t see any dimensions for the handheld controller so I have these measurements: 3x1.75x1 inches shaped like an hour glass. It’s too small for my hand. It may be best for a small child. The overall small size of the controller makes it harder to find the proper fit to a hand. The contoured unit is shaped like an small hour glass. The activation button is the same dull gray color and it’s only ¼ inch round . and it’s hard to locate and only on one side. It needs to be much bigger (the button ½ inch) and there should be 2 of them, and a neon glow color for rapid identification. The grey leash is accessing hanging from the necklace suspension, and about 80% of the time the palm of my hand wrapped around was totally out of place. It took 2 or more grabs to get the single activation button in an activation position. Larger and 2 extra buttons would be an improvement. The collar is long and rubber with the standard belt buckle design, NOT Velcro. Velcro would be easier to put on a bouncing puppy. On the recommendation of the mfg I trimmed the collar but just few weeks later because my puppy rapid growth , I had to buy another collar ………. $20 with shipping, or buy 3 and get free shipping ($45 for 3). In my option Velcro would be easier to fit and adjust. The batteries charge with 110 AC from a compatible sourse, like the wall. The charging light is steady during the charge and go to ”flashing” when charging is complete. The duration of the charge depends on frequency of the unit use. The zap is very short and has an aural beep when zapped. As the battery drains the flashing green changed to flashing red. The manual suggests that a charge will last 72 hours if not used. I’m not happy with the unit. It seems they should of had an interview questionnaire to assist on making a purchase decision more informed, such as dog type, long or short hair, The instructions are not simple. There are 3 plateaus for shocks at 21 level. I’m not clear how to change the settings. I think I’m on level 1.3 now, but not sure. I found the instructions confusing. Not knowing where the zap setting is was poor planning. Why not an LED scale for rapid referral to set the zap? The collar was purchased for training AND for safety interventions. My puppy is curious and is distracted when he gets close to a road with a speed limit of 25 (not the 52 everyone speeds at). It’s important to me that the collar can be used to change his run direction away from a danger. This unit seems only to work 20% of the time for a correctional change. We were at a local farm store when an elderly man came out and my Puppy 70 lbs at the time, began to pull me flat footed on pavement toward this man. I’m 230 +gun & amo and he was pulling me. I was pressing the zap button with nothing happening. I was yelling for him to stop. Finally the man began to pull his pistol. When I was 30 I could draw and fire from the hip in .26/100 second striking center mass. I shoot competition. I’m 68 and have slowed down to .68/100s …….. the old man saw the business end of a 45 auto. He stopped. We talked. We understand that the puppy thought the guy was our neighbor. THE fact is the SPTDOG failed during a critical time. SUNDAY DEC 12 2021 I’m sitting here with a pulled hamstring leg muscle. I can barely walk. I was taking my 85 lb puppy out for potty time. He saw a kitten on the front porch and puppy bolted through the screen door with my hand holding the leash, and other hand on my sportdog 425X shock button. Putty had the forward momentum and pulled me (220 lbs) off of my feet and across the deck. Down the steps in a single foot touching the ground 5 ft drop to the ground …… pulling my hamstring. THE SPORT DOG FAILED ……. FAILED TO SHOCK AND THE DOG DRAGGED ME DOWN THE STEPS AND ACROSS THE DIRT……….

High quality, great training collar
This is a great training collar. It is high quality and my dog has responded to it very well. I like the multiple functions and adjustability. I use the tone and vibration settings the most and the battery normally lasts a few days. It charges quickly and is durable.

quick results
I was very reluctant to purchase an e-collar as I was of the incorrect belief that they were a form of aggressive punishment. I decided to try this as a result of my dog trainer's recommendation. She also trained me on how to use it. I use this for off-leash "behavior shaping" and a pronged collar for on-leash correction (heel, calm-down when meeting people). I have an 85lb, 8mos adolescent Briard with thick hair that had basic training and who is a very sweet and wiling learner. He unfortunately developed a few brat behaviors that I couldn't figure out how to correct. Some examples are: tearing out huge mouthfuls of lawn like a game whenever I let him in the backyard, tearing the branches of low-hanging trees, eating acorns, mouthing smaller dogs at the dog park. He was easily corrected of all these behaviors using this collar in 1-2 sessions on a very low setting. He learned so fast it was like a miracle. I also use the collar to train him to "come" when off-leash. I use the "tone" setting to get his attention from a long distance and then reward him with a treat. Now, whenever he hears the tone, he looks around for me so he can get his reward. Before the collar conditions it was difficult to get him to come. Yelling, "come" was not reliable. The tone made all of the difference. I like the fact that this collar is water proof rather than water "resistant" and has a manual dial setting for the static electricity setting. The the dial insures that the setting doesn't accidentally get changed. Once you find the minimum setting that your dog responds to there is rarely a need to change it. The only criticism I have of the unit is the collar. This would be true of any e-collar. The buckle is a ROYAL pain to get on and off (i.e. my dog has a thick coat). I found that the third-party EDUCATOR QUICK SNAP BUNGEE COLLAR is the perfect solution. Its a little pricey at $27, but makes using the e-collar much, much easier to get on and off. Great training tool when you know what you are doing. Great purchase.

Es muy útil si tu perro ya está educado.
Me ha servido bastante porque mi perro le ladra mucho a otros perros cuando salimos a pasear, eso evita que se les aviente, una solo vibración y obedece al instante. Te recomiendo que lo uses solamente si tu perro ya está educado. Y leer todo el manual antes de usarlo.

Excellent service, no hassles!!!
Received item and was not paired and would not work. Contacted seller and they sent me new transmitter, still didn't work. Called them back and they sent a new collar to see if that would work and it did. Very happy with product and customer service is fantastic. No sence looking elsewhere.

Great customer service
I've used sportdog collars for my dogs for well over a decade. I mostly use them for off-leash hikes, just to ensure my dogs stay in close proximity while still getting to explore safely. While they were mostly used for my energetic young bird dogs, I also found them incredible as they got older and more deaf. Having a tone right near their neck or the vibration, they can explore without needing to hear me calling. Anyways- I just recently got two new dogs trained up on an old collar, and thought I'd order them their own. I got this and another add-a-dog collar, and set right to getting them all assigned to their proper button. I love that you can program it so easily for three dogs and still be able to use the tone (or vibration) and static correction. When setting up the new remote with an old collar and the two new ones, the one that came with the remote wasn't beeping due to a faulty speaker. I contacted the sportdog customer support live chat, and within 5 minutes I had a replacement collar on the way, without the annoying "well, did you turn it off and on" or "did you charge it properly" questions. Such wonderful service, and a great product. I always recommend this brand and will continue to do so!
