Not everyone is comfortable putting a shock collar on their dog, but a citronella collar is one way to reduce barking from your dog without any physical harm. The Gentle Spray collar releases a small amount of citronella scent when your dog starts barking.
Citronella is not a common smell and most dogs will react to its presence. Instead of continuing to bark, the dog becomes distracted by the smell and sound of the citronella being released. Training for the collar is as simple as strapping the collar onto your pet and letting the process happen naturally. Your dog will become aware of the consequences of barking over time.
This collar is not recommended for dogs who are barking because of anxiety. The smell may make the situation worse.
