Acme's dog whistles come in three popular frequencies: 210.5, 211.5 and 212. For small breeds like spaniels, try the 210.5, which works well in relatively enclosed areas. On the other hand, the 211.5 and 212 are better suited to long-distance recall exercises with larger dog breeds like retrievers and Labradors.

Almost all vets agree that positive reinforcement training is the most effective method of dog training. Positive reinforcement training essentially focuses on rewarding your pet for good behavior, rather than punishing bad behavior.

The most common signals include the palm facing out for “stay,” pointing forward for “go,” a flat hand for “down,” and a closed fist for “come.” For “sit,” use an upward-facing palm. Eye contact is crucial to reinforce the signal, ensuring that your dog understands what you are trying to communicate.

However, the dog whistle can be used to stop barking, train basic obedience, or even modify specific behaviors. Remember: without proper training, the dog whistle is just another sound in the world. Just like with other sounds, they will become desensitized to it and learn to ignore it over time, if not used properly!
