PetSafe NanoBark 2.0 Bark Collar vs SportDOG NoBark SBC-10 Bark Collar

The SportDOG SBC-10 is the better collar for most owners. It scores higher with owners (4.3 from 189 ratings versus 3.9 from 71), offers two correction modes, and recharges in about two hours. The PetSafe NanoBark 2.0 is built for tiny necks of 4 to 15 inches and runs up to 7 days on its battery, but its fixed auto-adjusting static gives you less control over a stubborn barker. Choose by dog size and how much control you want, not by brand.

• Choose the PetSafe NanoBark 2.0 if you have a small or miniature dog with a neck under 15 inches and want a light, waterproof collar that adjusts correction on its own.
• Choose the SportDOG SBC-10 if you want manual control over correction levels, a fast rechargeable battery, and a collar that suits medium to large dogs.
