Nunbell Adjustable Half-Choke Dog Training Collar offers the perfect solution for pet parents seeking professional-grade training control without compromising their dog's comfort.

Commonly known as a martingale or limited-cinch collar, this design provides a gentle, even correction when your dog pulls, then relaxes instantly the moment they stop. Unlike traditional full-choke chains, the integrated nylon backing limits how far the collar can tighten, protecting your dog’s throat, minimizing coat friction, and preventing accidental slips.

Key Features & Benefits

• Trainer-Recommended Control: Provides gentle, audible chain feedback that naturally deters pulling, making it an excellent tool for obedience training and daily leash manners.
• Premium Stainless Steel Chain: Engineered with a heavy-duty, rust-resistant stainless steel loop and O-rings designed to glide smoothly and withstand high-tension pulls.
• Heavy-Duty Reinforced Nylon: Constructed from dense, premium-grade nylon webbing that is soft against the fur yet exceptionally strong and weather-resistant.
• Quick-Release Safety Buckle: Features an ergonomic, high-impact plastic buckle equipped with an integrated manual Safety Lock to prevent accidental unclipping.
• Fully Adjustable Fit: Easily customizes to your dog's exact neck proportions via the slide buckle, ensuring the collar sits securely and comfortably.

Available Sizes (Width Options)

This single listing features an adjustable length across two versatile strap widths to match your dog's size and pulling power:

• 15mm Width: Ideal for puppies, small, and medium-sized breeds who need lightweight control and lightweight hardware.
• 20mm Width: Perfect for medium and large-sized breeds requiring a thicker strap footprint for better pressure distribution and higher tensile strength.

Note: Colors are sent as per availability (Vibrant options include Blue, Red, Grey, Purple, Orange, and Green).

How to Use for Best Results

1. Adjust the nylon strap so the collar fits comfortably around the upper neck behind the ears when relaxed.
2. Slide the Safety Lock to the unlocked position, clip the quick-release buckle around your dog's neck, and engage the lock back into place.
3. Attach your favorite walking leash directly to the outer O-ring on the steel chain loop.
4. Enjoy a controlled, slip-proof, and calmer walking experience!
