Four things that work on the same problem from different directions: a collar that interrupts barking when you are not in the room, a calming collar and a chew that work on the state underneath the barking, and a spare can of citronella so you are not caught out mid-training. This is the version for barking that happens without you — the postman, the doorbell, the dog next door, barking while you are at work or asleep. If you want to be the one deciding when a correction happens, the remote-controlled bundle is the one to look at instead. What is in the box Deluxe Automatic Citronella Spray Collar — detects barking on its own and releases a short burst of citronella mist. No shock. Up to 60 days per charge, IPX5 rain resistant, fits dogs 5–60 lbs with necks up to 27 inches. Ships with its own citronella can. Citronella Spray Refill — a spare can. The collar arrives with one already; this is the second, so you do not run dry a fortnight in. Calmdogs® Calming Collar — worn daily, lasts up to 60 days, adjustable to a 27 inch neck, non-sedating. Calmdogs® Dog Calming Treats — 120 turkey-flavoured soft chews, 2.5 g each. A complementary feed with chamomile, valerian root, passionflower, L-tryptophan, L-theanine, ashwagandha, ginger and magnesium. Why four things rather than one A spray collar interrupts a bark that is already happening. It does nothing about why the dog was wound up in the first place. The calming collar and the chews work on the second half of that — not as sedatives, and not quickly, but as background support while the training does the actual work. Neither half is sufficient alone, which is the honest argument for buying them together rather than a marketing one. If you only want the collar, buy the collar.

A deep-voiced large dog may not trigger it as reliably. If that is your dog, ask us before ordering rather than after. The chews are turkey-flavoured, so they will not suit a turkey-sensitive dog. The calming collar is trimmed to fit and worn continuously, which some dogs object to at first. A collar of this kind is a training aid, not a substitute for training. Use it during periods you cannot supervise rather than as an all-day fixture, keep continuous wear under 12 hours, and pair it with consistent reward-based work. Calmdogs® Dog Calming Treats are a complementary feed, not a veterinary medicine. They do not diagnose, treat, cure or prevent any condition. Individual dogs respond differently. If your dog is barking from genuine distress at being left alone — rather than at a specific trigger — that is a behavioural problem rather than a training one, and it is worth speaking to your vet or a qualified behaviourist before buying equipment.
