Specially designed for these dogs, its wide, weather-resistant band lies flat against the coat, preventing it from getting lost in the fur. Thanks to its 360° light ring, this collar makes it easy to spot your companion in the yard or at the park (and ensures visibility to drivers). Simply press the button to turn it on and cycle through the three available colors (red, green, blue) or the "Disc-O" mode, which blends colors for a unique effect. The band can be trimmed at the end for a perfect fit, accommodating neck sizes from 30.5 cm to 68.6 cm (12 to 27 inches). Rechargeable in 2 hours via a micro-USB cable (not included), the NiteHowl Max offers a 10-hour runtime to keep up with your furry friend.
