I have an Educator 400 series, which was recommended by a dog trainer friend. I have two White Swiss Shepherd dogs and I am sure that many of you with two dogs know, trying to get them to pay attention to you is a challenge especially in difficult situations. We live in the Scottish Borders and our walks are mainly in the surrounding countryside. We have a lot of sheep and sometimes these are free roaming. We also have deer, squirrels, hares and rabbits. So the challenge is to essentially control the dogs prey drive.
Using a distance control collar makes this easy. I started off with squirrels and the dogs very quickly learned not to chase them. They now check in with me with a look and just leave them alone. I then moved on to sheep, with the blessing of my local farmers. We had a couple of episodes of chasing, which were halted by the collar, on a level high enough to stop the chase immediately and see an immediate return to me. Basically this was end of story. I now walk regularly through sheep, in the absolute certainty that the dogs will not chase the sheep.
I have done the same thing with deer and hares, but don't tend to see these so often, so I can't be absolutely certain that they won't show interest, but I am certain that I can control this quickly and easily.
My young dog is also quite nervous and is reactive with other dogs, Again I can now control this well with taps on the collar and low level: this just ensures that she pays attention to me and not the other dog.
Recalls and heels are made a breeze with the collar and it is possible to walk along with both dogs at a very acceptable heel without any other lead. I wouldn't do this in a town or other more dangerous situation but this is really only for other people's peace of mind.
The Educator has given us a totally stress free life with the dogs, because I know that I can control any undesirable behaviour at a distance. This makes me relaxed and hence my dogs are relaxed.
