Citronella training collars use a harmless burst of citronella spray to interrupt unwanted behaviours. Depending on the model, they may also incorporate additional training modes such as audible warning tones and vibration to provide a more versatile training experience.

Popular with dog owners who prefer a non-static training approach, citronella collars can be an effective option for addressing nuisance barking and other unwanted behaviours while helping to reinforce positive habits.
