WeAreK9 20mm Waterproof Martingale Dog Collar
Made-to-Measure | Durable | Small–Medium Dogs | UK Handmade
Our 20mm Waterproof Martingale Collar is designed for reliable control, comfort, and everyday durability. Handcrafted in the UK using premium waterproof webbing and rust-resistant chain hardware, it’s ideal for training, structured walks, and active dogs in all weather conditions.
Lightweight. Strong. Practical.
Made-to-Measure Fit
Every collar is made to your dog’s exact neck measurement — no generic sizing.
Your measurement will sit at the midpoint of the adjustment range, allowing room to slightly tighten or loosen if needed.
This ensures:
Secure, escape-resistant fit
Correct martingale function
Clean, balanced proportions
Please measure carefully before ordering. Smaller neck sizes will naturally have a reduced adjustment range due to chain proportions.
