What people are saying
Every dog should have one!
The Whistle has been an amazing addition to our family. I think what we have been most impressed with is how durable the device is. Ripley has put it to its test with playing with other dogs, swimming (even in frozen water!) and plenty of hikes and the Whistle won’t give in. Every dog should have one!
