PetSafe NanoBark 2.0 Bark Collar for Small Dogs - Lightweight, Adjustable Dog Collar - Smart Bark Detection - Auto-Adjusting Static Correction - Waterproof & Rechargeable - 4–15"

Small dogs have big voices, and they deserve tech that’s tailored to their size. NanoBark 2.0 Bark Collar is built for dogs with neck sizes 4 to 15 inches and helps stop nuisance barking, so you can enjoy a peaceful home together. 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. The slim, low-profile bark collar features a snug new fit with an updated design for extra flex and durability. Delivering the minimum effective level of correction for max results, it only responds to your dog’s unique voice and tunes out the neighborhood noise. With 10 levels of auto-adjusting static correction, the bark collar helps prevent your dog from growing desensitized with patented Variable Pulse technology. The long-lasting battery stays charged for up to 7 days, and the waterproof design means you can enjoy puddle play with ease. Note: This product uses static correction. If another type of correction is desired, PetSafe offers a variety of collars that use other forms of correction, including tone and spray.
