LIVELYLEAP'S VISION Dogs are human's best friends, the most loyal companions, and close family members. We hope to find a humane, safe and effective way to stop dog barking. The dog bark collar comes with citronella spray to train your dog to bark less, behave well and develop good habits quickly. No sound nor vibration will be made to irritate your dog during barking reduction process. It helps your dog learn how to stop barking without your participation. How to fill citronella? 1. Press the gas cylinder on the desktop to confirm whether there is gas. (crystallization occurs on the desktop) 2. The collar shall be placed horizontally, and the inflation bottle shall be vertically downward. 3. Confirm that the inflation port is correct, and press it for 15 seconds to fill the air. (It is recommended to fill gas before each use) Safe & Effective & Humane 1. When the citronella bark collar senses a bark it will release a short burst of citronella spray. 2. Train your dog effectively with no painful stimulation, a humane anti barking collar for dogs.  Warm tips: 1. The barking collar for small medium large breed only barking twice or more in 10 seconds will trigger the spray, which is more humane, safer and more effective than electric shock collars. 2. If you need to adjust the strap and cut the redundant part of it, heat the end of the strap with a lighter, in case it get a raw edge. 3. Wear the small dog bark collar on the neck of the dog and install it well, with the spray nozzle aligned perpendicularly to the dog's nose, and the wearing criterion is based on the extent that one finger can be accommodated between the collar and the dog's neck. This can accurately identify the frequency of the dog's barking. Too much relaxation of the no bark collar will lead to uncoordinated action and affect the normal operation of the citronella dog collar. 4. For a dog with long hair, it is necessary to trim the hair on the spray path to ensure that the mist can be sprayed to an effective range. 5. If you want to test the stop barking dog collar before putting it on the dog, please turn on the collar, blow to the microphone to test the collar (Be careful to spray the citronella into your eyes). 6. It is recommended to fill with gas before each use. If you want to refilling the citronella spray, please hold the refill spray can upright and vigorously and firmly press the nozzle down into the refill port for 15 seconds. 7. Don't let the dog alone at first several times. Spray warning can distract your dogs' attention and stop barking. At this time, try to praise them so that they can remember the warning. If your dogs struggle with spray warning, try to guide and comfort them to help them adapt to it for a few times. 8. Our bark training collar is NOT intended for use on dogs under 6 months old and less than 8 pounds, aggressive dogs/long nose dogs/smelling impaired dogs/long neck dogs. 9. Please scrub around the neck of the dog and the induction head of the no shock bark collar every week. Note: Our citronella bark collars are effective in stopping barking in most dogs, but there are a very small number of dogs who are not afraid of citronella spray and may not have a bark stopping effect.
