Yes. Actually, she's pertrified of anything making a mettalic sound. I only used it one time (Pepsi can with a few pennies in it) and from that point on, all I have to say is "Stop it or I'll get the CAN" and it works for everything. If she continues to be so involved in catching her prey, I will take the can outside and give it a few good shakes with "NO DIGS" and she gets submissive and practically crawls over to me. I guess it depends on the dog. Cody could care less, it was "Oh, it's the can again, yawn". Remember to catch her in the act as you use the can. Cheap, safe and effective.
