For hygienic reasons dogs are not allowed to enter the water of a biological pool. This is exclusively intended for bathing people.
The solution of a fence that is surrounding the entire facility does not please all owners. There is now a novelty, an electronic solution consisting of a collar for the dog and a buried wire that runs around the whole biological pool. The wire works like an antenna and the animal receives a strong signal when it tries to approach the water through the buried wire.
Dogs learn the signal soon after the first attempt and no longer continue to approach. With this solution they can stay in visual contact with their owners in the areas adjacent to the biological pool.
