Buzz, the dog in question--although not as experienced as his age would indicate--is 8. If you know the stimulation level to which your dog responds, I don't think there's much danger. You certainly don't want to fry a dog that refuses to drop. However, trainers regularly use an ecollar "nick" to remind a dog that locks up and then starts to creep in on the bird, and they wouldn't do that if they thought it likely it would cause the dog to blink birds or anything of that nature. But you do need to know when to apply juice, and at what level. A dog's owner should know that if he's trained and hunted with an ecollar.
