This is our automatic citronella bark collar with a spray refill cartridge included in the box — so spray mode works straight away, no separate purchase needed to get started. How the automatic bark detection works The collar's built-in sensor detects your dog's bark and responds automatically — no remote, no timing it yourself. In spray mode, the response escalates in steps: the first bark triggers a sound warning; if barking continues, the second bark triggers the citronella spray. If barking still continues, the collar repeats the warning and sprays twice in succession. This step-based approach means your dog gets a warning before the spray, not spray on every single bark. Modes and sensitivity A mode button cycles through response types — sound only, vibration only, sound with spray, and combined modes — so you can start gentle and add the spray response only if you need it. A separate sensitivity setting (1–5) controls how easily the collar triggers: lower for noisy households, higher for quiet ones. Setting 0 is a safe test mode, so you can confirm the collar is working — sound, vibration and spray — before it ever goes on your dog. Refilling the spray Each fill gives around 25 sprays before the display shows a low-spray warning. To refill: turn the collar off first, then press the refill bottle straight down into the spray inlet and hold for 10–15 seconds before turning the collar back on. Charging is via USB-C, and the collar should only be charged with a standard 5V charger — anything higher can damage the circuit and battery. Is it right for your dog? Suitable for dogs aged 6 months and over, weighing 8 lbs or more. It's not suitable for aggressive dogs. Like any bark collar, don't leave it on for more than 12 hours at a stretch, and check your dog's neck weekly for any rash or irritation, cleaning the neck area and the collar's sensor at the same time. This bundle includes one citronella spray cartridge, so the spray response works straight out of the box — no separate purchase needed.

Yes — this bundle includes one citronella spray cartridge, so spray mode works straight away. No separate purchase needed. Why isn't the collar responding when my dog barks? Set the sensitivity to 0 (test mode) first to confirm the collar itself is working — it should respond with sound, vibration and spray. If it works in test mode but isn't catching your dog's actual barking, set the sensitivity to 5, the most responsive level, and try again. Can I use it when my dog is playing with other dogs? It's not recommended — dogs tend to bark and get excited while playing, which can trigger the collar unnecessarily. Best used during normal daily activity rather than active play sessions. How do I refill the spray cartridge? Turn the collar off first. Line the refill bottle up straight with the spray inlet, press it in and hold for 10–15 seconds, then turn the collar back on. Each fill gives roughly 25 sprays. Is this collar safe to use every day? Yes, within sensible limits — no more than 12 hours' continuous wear, with a weekly check and clean of your dog's neck and the collar's sensor. The citronella spray is non-toxic and safe for daily use.
