Guess which one of these collars will keep your dog safe today?

(Roll your mouse over each photo to find out)

Yes, this one is working … you can tell by the flashing green light.

This is the collar used by Derby's Pet Fence, it flashes green every few seconds to assure you that it is working and will keep your dog safe. If the light blinks red or stops flashing, then it is time for a charge. So, everyday when you put the collar on your dog, you will know FOR SURE that your collar is working properly.

Not this one … It's got a dead battery

This is a collar from a popular competitor. It has no light. There is no easy way to know if this collar will keep your dog safe. Even if you just put in a brand new (and expensive) battery, wouldn't it be nice to have some confirmation that you didn't put it in upside down?

Not this one … It's got a dead battery

This is a collar from a popular competitor. It has a light, but it only flashes when the battery is very low. Of course, after a while the low battery light will STOP flashing when the battery is totally dead. So ... When you look at this collar and the light is NOT blinking, you have a 50-50 chance that it's working. In this case, it's dead.
