Should I buy SportDOG FieldTrainer 425X Dog Training Collar

If you’re like me and love dogs, you’ve probably spent a lot of time trying to figure out if SportDOG FieldTrainer 425X dog training collar is right for you or not. Great dog breeds don’t always come with the right training ability. Training your dog to listen is a skill that takes time to master. You have to build your dog’s behavior and train her over time. It’s important to work with your dog in a positive and fun way so that she doesn’t become bored or frustrated.

The problem is that Zoey, my dog, loves to chase things. I don’t like the idea of her chasing things outdoors because it can get messy and dangerous. So, to help solve this problem, I introduced the SportDOG FieldTrainer 425X. By teaching Zoey where to go with the remote trainer into our training sessions for a few weeks, Here’s how this remote training collar worked for us.

SportDOG FieldTrainer 425X


Top Pick
SportDOG FieldTrainer 425X


  • 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 range of the SportDOG FieldTrainer 425X is up to 500 yards. I found out that depending on several factors, specifically indoor viz-a-viz outdoor, including the terrain and weather, this range could be at times less or even more. Though I did not face any problem related to its range, if you are planning to use it for hunting or field dogs, you may need a field trainer with longer ranges.

Battery Life

SportDOG Brand 425X is a rechargeable lithium-ion battery powered dog training collar that recharges in about two hours. It comes with a single charger to power up both the receiver and remote at the same time. When you buy a collar, you are buying a piece of equipment. An accessory that needs to be charged. You may want to consider purchasing a collar with rechargeable batteries so that you won’t have to replace the batteries as often. This will save you money in the long run. 

I found out that the battery lasts for about 60 hours per charge. Meaning by that if you train your dog for 60 minutes every day then you will require it to charge once a week. The manual along the package claims that batteries would last for 3 -5 years (Obviously, now I can not verify the claim)


It is the smallest and lightest but solid and well-made training collar I have ever used with a remote which is quick and operates easily without having to look at it – which lets me focus on my dog and not on my remote. With only a slight movement of the dial and the push of a button, I was able to deliver a tone, vibration, or one of the 21 levels of static stimulation. Dog training gear is one of the most important pieces of equipment that you’ll need if you want to train your dog.

The receiver fixed on the collar is lightweight and it is attached with a strap with metal buckles. The collar can easily be used on a dog with an 8 pounds dog or larger with neck sizes 5 to 22 inches. I cut down the plastic collar to fit Zoey’s neck and it was good to go.

Zoey Experience with SportDOG FieldTrainer 425X

My dog Zoey loves to chase things outdoors. So my basic concern was to change her behavior so I can take her for a run outside. I started my training sessions with her using SportDOG FieldTrainer 425X. Initially, when I let her loose and tried to give her command through the remote, she ignored it. Then I used the remote to provide her continuous stimulations until she turned back and started moving back to me. By reading through the manual provided along the collar, I was easily able to train her within a month.
