The best product on the market!
I have 2 Belgian Tervurens , Zeus is 2 and Tiger is 5 months , so if anyone knows the breed knows how much work it is when their are little! So for my 2 year old I tried dog trainer and a collar he suggested . The worst decision ever ! When I picked him up in 2 weeks he was so stressed I thought he’s going to a have a nervous break and the collar I paid $250 for ( E-Colllar Technologies ) made him squeal and scared ! We live in the ocean state so we went to the beach for the first time , I had the collar on him , seemed to have a good time , I had to correct him a couple of times , went to local pet store to take a bath after and when I was drying him I saw awful irritation all over the front of his neck ! I called the company when got home, I said it said it says guaranteed waterproof the guys who answered the phone goes YES I DONT KNOW MUST BE SOMETHING YOU DID ! I threw the collar in the trash ! Went and got him PetSafe , I love it , he loves it , no problem! So now the baby loves to swim and unfortunately chase the seagulls and doesn’t listen. I went to the PetSafe website saw the othe brands they have , the waterproof fieldtrainer 425s and bought it. Received today , went to the beach , works great ! No more chasing birds listens like a good boy on the lowest level , nothing on his neck , I’m very happy! I’ll be buying a second one for my 2year old the next couple of days since he loves to swim to and sometimes doesn’t like to share his tennis ball . Very happy with the purchase, I will recommend it it to everyone I know!

Just What My Dog Needed
We bought a yellow lab . She was just 6 weeks old when we got her which turned out to be too young because she never had the benefits of mom and litter mates manners training. She is a sweet and beautiful pup but is a real rough houser. A lot of her behavior problems were unacceptable. We read training books and talked to her vet and in desperation even considered a "SHOCK COLLAR". My wife was really against it but after talking to our vet and to the trainer we took her to we decided to go ahead with it. My vet told me that the people who were so anti-shock collar had just never used one. I bout the plus model for more stubborn dogs. It has been a wonderful tool. We have been using it for almost two years now. She does not like it and it can be difficult to get it on her every morning. We also learned we needed it to be much tighter. After she started to get the point that not minding meant a correction shock she is so much easier to control. She is smart but she is big, hard headed and still likes to rough house with me. My wife and I are in our sixties and just not capable of physically restraining her but when you show her the remote that is usually all it takes, sometimes a vibration but seldom any I mean business shocks anymore. The unit has been reliable and the only breakdown with it involved her getting ahold of the transmitter one day when we were not paying attention. She destroyed it. The people at Sportdog sent me a new one at a reduced price. If you have a problem dog that you love don't hesitate to check these out. It allowed us to be able to keep the dog we love.

Great trainer!
Don't know how I would have managed my coonhound puppy without the 425S. At 2 years of age he will still follow any scent he comes across, and pursue any living creature that moves. Certainly not an easy breed to manage off-leash, but this collar has made it possible.

I initially purchased a Yard Trainer model, but found that my dog needed a greater stimulus, over a longer range. The 425S was the perfect match. I would recommend that anyone training a larger dog, of an adventurous or working breed, start out with one of the Field Trainer models.

Many thanks for a great product!
