Great product and customer service!
I just recently bought my own home, and my stubborn Shepherd/Collie pup wouldn't listen to me once he was outside. After a few times of running over into the neighbors yard (not a friendly neighbor), I decided to give the e-collar a try after several of my friends recommended it. It works great. If he doesn't come when I call him, I only ever have to tone him once and he is listening to everything I say. I rarely ever have to use the stimulation button. Now that we have had the collar for a while, 75% of the time anymore I don't even have to tone him and he comes to me. He comes every where with me, and it really has been so useful and such a relief for me knowing that he can come along and behave while having fun at the same time. I've only had one problem with my collar and that was two weeks after I bought it from Field and Stream. Stimulation levels one and two weren't working anymore, and I didn't dare use the level three button when it wasn't necessary. I took the product back and customer service was very polite and helpful, giving me a brand new collar and remote and some useful tips on how to make the battery last as long as it can. Granted I did pay for a two year warrenty, I never expected that I would be given a brand new product. I'd recommend Sport Dog to any of my friends.

Great tool!
I have a 95lbs shepherd who is very good motivated and is a wonderful dog, but when he got outside he would run and run and run and it became a game. After the collar, his recall has become golden. We also have been able to stop his mounting problem.

Question! The remote transmitter, is it also waterproof or is it only the collar? We went swimming and I wasn't sure if the remote would be safe. He tends to think others are drowning so I wanted to be able to correct him while we were swimming.

SportDOG Response:

Thank you for taking the time to provide feedback! The collar as well as the remote are completely waterproof and submersible with the SD-425S design. If you have any further questions about your system feel free to give us a call directly at 1-800-732-0144. Our office hours are Monday through Friday 8 A.M. – 8 P.M. ET and Saturdays 9 A.M. – 5 P.M.

Finally found the right collar
Our Great Danes are quite stubborn on when they wish to listen and when they don't want to. This collar finally makes them listen, yet have freedom to play in our yard!
