Small dogs have big barks, and sometimes they forget to use their inside voice. The PetSafe® NanoBark™ 2.0 auto-adjusting bark collar puts smart bark control in a revolutionary small design to keep your home quiet and peaceful. NanoBark™ 2.0 dog collar responds only to your dog's unique voice and tunes out the neighborhood noise to help reduce nuisance barking. It uses patented advanced tech to deliver the minimum effective level of static and prevent your dog from growing accustomed to the correction. With a long-lasting battery and a comfort-first fit, NanoBark™ 2.0 bark collar for small dogs is perfect for apartments, houses or anywhere in between.

Big tech in a tiny collar

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

Next-gen bark collar that learns from your small dog's behavior

Our patented Perfect Bark® technology learns to recognize your dog's unique bark and barking habits. It only responds to your dog's bark, ignoring other sounds like nearby barking friends or other neighborhood sounds. By learning your dog's vocal patterns, NanoBark™ 2.0 bark control collar automatically adjusts through 10 stimulation levels, ensuring the minimal level of correction is applied.

Go from yappy to happy with NanoBark™ 2.0

Variable Pulse™ technology prevents your dog from growing accustomed to corrections by increasing the number of static pulses before increasing the static intensity, resulting in gentler and more effective bark control. No more worrying if it's too much or too little, now you can have confidence in every correction.

Go up to one week on a single charge with the improved rechargeable battery on 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.
