A martingale collar is designed with a two-loop system that gently tightens when tension is applied, helping prevent dogs from slipping out while remaining comfortably loose at rest. This “limited-slip” design offers added security compared to a standard buckle collar, without the need for a tight fit at all times. Designed in Austin and produced locally in small batches, each piece reflects a focus on material quality, thoughtful construction, and a clean, considered finish.
