For a Cocker Spaniel, go for something like the Acme 210.5 whistle. It has a slightly higher pitch, which suits spaniels working close and reacting quickly. It helps keep communication sharp when they’re busy flushing in front of you.

For Labradors and retrievers, a Acme 211.5 whistle is the usual choice. It’s a deeper tone that carries better over distance, ideal for dogs working further out. You’ll find it much clearer for stop and recall commands in open ground.

A silent whistle (often ultrasonic) is used when you don’t want to disturb wildlife or other people. The dog still hears it clearly, but it’s much quieter to us. It’s useful for discreet handling, but beginners often find standard whistles easier to learn with first.

It matters more than people think. Different whistles carry differently in wind, rain, and distance, and your dog will tune into that exact pitch. Pick one early and stick with it, consistency beats “the perfect whistle.”

Only as loud as needed, not full blast every time. Think of it like a volume dial: quiet for close work, louder for distance. Constantly blasting it can make the dog less responsive over time.
