Small dogs have big barks, and sometimes they forget to use their indoor voice. The PetSafe® NanoBark™ 2.0 auto‑adjusting bark collar delivers intelligent bark control in a revolutionary compact design to keep your home quiet and peaceful. The NanoBark™ 2.0 dog collar responds only to your dog’s unique voice and filters out neighbourhood noise to help reduce nuisance barking. It uses patented advanced technology to deliver the minimum effective level of static correction and to prevent your dog from becoming accustomed to it. With a long‑lasting battery and a comfort‑first fit, the NanoBark™ 2.0 bark collar for small dogs is ideal for flats, houses or anywhere in between.

Big technology in a tiny collar

Suitable for a King Charles spaniel or any regal beagle, the NanoBark™ 2.0 collar is perfect for all dogs with necks measuring between 4 and 15 inches and weighing 8 pounds or more. The slim, low‑profile dog collar is smaller than a smart watch, making it secure and discreet, because tiny dogs deserve technology that is tailored to their size. The snug, new fit also features an updated design for extra flexibility and durability.

Next‑generation bark collar that learns from your small dog’s behaviour

Our patented Perfect Bark® technology learns to recognise your dog’s unique bark and barking habits. It responds only to your dog’s bark, ignoring other sounds such as nearby barking dogs or other neighbourhood noises. By learning your dog’s vocal patterns, the NanoBark™ 2.0 bark control collar automatically adjusts through 10 stimulation levels, ensuring that only the minimal level of correction is applied.

Go from yappy to happy with NanoBark™ 2.0

Variable Pulse™ technology prevents your dog from becoming accustomed to corrections by increasing the number of static pulses before increasing the static intensity, resulting in gentler and more effective bark control. There is no need to worry whether it is too much or too little; you can now have confidence in every correction.

Rechargeable and waterproof anti‑bark collar

Enjoy up to one week on a single charge with the improved rechargeable battery in the NanoBark™ 2.0 bark collar for small dogs. Easy to use and intuitive, the collar is simple to recharge and comes with a USB‑A charging cable. In addition, you can comfortably walk in the rain with the NanoBark™ 2.0 bark collar because it is waterproof and designed to withstand any spontaneous puddle‑jumping. Your pet deserves the best.
