Review on ACME 717668122103 210 Orange Whistle by Leah Johnson

7 month old labrador reacts to this like nothing else. We use this for more urgent reminders (e.g. when she runs to a stranger on the beach or out the garage door) and ALWAYS reward the whistle with real dried chicken delicacies to make the whistle stronger. She will even get out of confusing play with other dogs if we whistle at her. Otherwise, she may be deaf to verbal memories when distracted. We attach it to one of those elastic spiral bands and always take it for a walk because you never know when you might need it. We have 4 of these, one on each door and one on each retractable leash. Affordable comfort is a must.
