SportDOG FieldTrainer 425 Series

The FieldTrainer 425S E-Collar has forever changed my life for the better. Having complete control over my dog from yards away and while he is in the water makes being a dog mom so much easier.

If you are like me and have a giant puppy who loves to play other dogs (and occasionally mount them to show of his male pride you know that it is difficult and straight up annoying and can even be embarrassing to have to run, yank your dog off or pull him away from whatever you are doing and proceed to discipline them.  My times of losing my breath and temper from constantly chasing my dog when we went to the dog park are now long gone, and it’s all thanks to my e-collar. I can now tell Zeus what he is doing wrong at the exact moment it happens, from the push of a button.

After deciding that one day we had enough of trying to teach Zeus manners at Bear Creek Dog Park, we made a stop at Petco on the way home. They had a small selection of e-collars. Having done some previous research I knew that we wanted to get something that had multiple shock levels and that was waterproof. The only collar at the Petco we visited that held these characteristics was the SportDOG FieldTrainer 425 (not 425S – which this review is on). $200 later we were on our way home excited to try out our new purchase to see if it worked. The next day I headed back to the dog park with my ill-mannered Cane Corso who was wearing his new shiny e-collar. The FieldTrainer 425 has seven levels that vary in shock intensity (one being low and seven being medium amount of stimulation). I found out very quickly that my hard headed pup could easily withstand all seven levels that this collar had to offer. Beaten and bitter I came home and got on the Google machine to see why this collar sucked so much – I did not know that there were two levels of this collar, the FieldTrainer 425 and the FieldTrainer 425S. We had purchased the 425 which gives off low to medium shock stimulation, perfect for dogs who just need a little correction. The 425S gives off medium to high shock stimulation. The collars are the exact same, except for this difference. The next day I made my way back to Petco to exchange for the level up of the FieldTrainer for my stubborn pooch, only to be discouraged when I found out that they did not carry it. I found the collar online from Amazon (for cheaper than what we paid at Petco) and received it in the mail the next week. Again, we went to the dog park to test out the new collar and this time I came home with a huge smile on my face. Every time Zeus tried to mount a poor innocent female or was getting a little rough with another dog I could simply tell him no, and if he didn’t listen to me I could press my button on my remote and he would be reminded that I said no and he would stop. I felt so powerful and like I had so much control.


The collar is made up of a plastic-like band that buckles together and in the middle you will find a little box with two prongs sticking out that deliver the electric shock. The collar comes with a small remote that easily fits in your hand. It has a knob to adjust the levels and two buttons – one button allows you to give a short instant shock, and the other you can hold down to deliver a shock that lasts up to ten seconds (aka to use when you dog is really not listening). A lanyard is also given to you so you can connect the remote and let it hang around your neck while out with your dog. The collar and remote come with batteries that are rechargeable, and you are given a single charging cord which can fuel both items at once.


The SportDOG FieldTrainer 425S has a range of 500 yards.


The collar takes approximately two hours to charge and should last for a minimum of 50 hours.


The best thing about this collar is that it is waterproof and can be submerged in up to 25 feet of water. If you have a dog that loves to run in the water or swim this is perfect for you! And it definitely comes in handy if you run into some rain unexpectedly.


If your collar ever needs a replacement or you want to change up the color of your strap SportDOG offers a bunch of accessories.


Dogs over 8 pounds or with necks that are from 5-22″ around.

This post probably screams I love this collar already, but it is the truth. A larger investment (costing about $200), but worth it in the long run. We’ve had the collar now for a little over a year and so far have had no issues. The remote is small and fits in your pocket or easily hangs on a lanyard they provide so you can throw it around your neck. I love that it is waterproof and I don’t have to worry about it breaking if Zeus dives into the water with it on. I highly recommend buying this collar for you pup if you are looking for an e-collar.
