Great for aggressive dogs
5 out of 5
5 out of 5
Summary:The people who designed the SD-425S had stubborn dogs in their minds when they created this product. I’ve tried it on my aggressive dog and it really works. I’ve used it for training my dog for yard, field or hunting work. I knew my dog needed a higher correction level since we’ve tried a lot of collars and nothing worked on him. He didn’t even flinch the last time we tried the highest stim level on him using a different collar. Good thing I found the SportDog for stubborn dogs.
Pros:Level of stimluation, Best Range

Summary:It has been 16 weeks since the first day we tried using this collar and it has done nothing but impress me. The collar has been performing very well on my dogs. It is very easy to use even for a first time user like me. I was initially scared that it would be all too confusing but it turned out to be simpler than I expected. The batteries are great. You only have to charge them for a quick 2 hours and you can use them for a whole day with normal usage rate. I like the soft feel of the transmitter. It is very comfy and pleasurable to hold.
Pros:Impressive, Comfortable, Best batteries
Best money ever spent

Summary:I’m not really sure of the exact breed of my dog but one thing’s for sure, he is very hard-headed. Once he is in his “zone”, there’s no stopping him. He will bark at or run after just about anything and there’s nothing I can do to stop him. He just has a mind of his own. Well, all this were true before we used the SD-425S. Before this collar though, I did try another collar that wasn’t effective so I did some more reading and found this collar. I was looking for something that was effective for stubborn dogs, had a decent operating range, waterproof and simple to operate. If you have a stubborn dog like mine then this training collar is the right choice
Pros:Waterproof, Easy Operate, Decent Range, Effective
I choose SportDog

Summary:I first bought a SportDog 400 for my first dog. He was fond of chasing after birds when he is not on leash and would only come back on his own terms. The collar helped me solve that problem. Now when she sees birds or other animals and starts to chase after them, I just give him a beep and he turns right back around. I think I’ve only used the shock button on him twice and that was it. I just got another dog and was about to use the same collar on him but I decided to buy the SD-425S for stubborn dogs. My second dog seemed more aggressive. I tried the first collar on him but it didn’t work on him. It was a good decision to try the first collar on him first. At least I knew that it wouldn’t work on him. The SD-425S on the other hand did work on him. He was trained in just a few days and it works perfectly well. I am very happy with my SportDog collars.
Pros:For stubborn dogs, Works Perfectly
One of the best

Summary:I have a very stubborn dog and this collar has been a lifesaver. I was about to give up on my dog. I was ready to accept that there is no way in the world that I will be able to control him. We’ve tried professional trainers and several collars but we were unsuccessful. I guess my dog needed something a lot stronger. And the SD-425S was indeed strong enough form my dog. This collar not only got his full attention, it allowed me to teach him a lot of commands. He has been very obedient ever since we trained him using this collar. Aside from it being very effective, the collar has a lot of features. It is waterproof and comes in 7 different modes. It is very easy to operate too. This collar is one of the best!
Pros:Different modes, Easy Operate, Lot features, Effective
