Comments about PetSafe PetSafe Yard and Park Dog Training Collar:
I bought this for my 10 month old lab puppy. He chewed everything and jumped on everyone. He even knocked people over, no one was safe. Although well trained he gets very excited and he's off. I used the "electronic stimulator" it once and since then I only need the warning buzzer. It didn't hurt but it startled. It really does help him remember what he learned....quickly. Best of all, we can go to the river for a swim and I don't have to worry about the collar. Waterproof is excellent.
