Fi Compatible Series 3/3+ 1" Width BioThane® Martingale Collar

Take your dog on any adventure with confidence, thanks to BioThane® - the 100% waterproof, dirt-proof, and adventure-proof material. Whether your dog loves to swim, hike, surf, or play in the mud, our BioThane® gear is designed to keep up with your dog's active lifestyle. With a range of colors to choose from, you can find the perfect collar to match your dog's personality. Martingale collars are specifically designed to provide more control than a standard collar & (when fitted properly) will prevent your dog from escaping or backing out of their collar due to the cinching function. While martingale collars don't prevent pulling, they are an excellent training tool for teaching your dog good leash manners. Please be sure to follow our "how to measure" guidelines below to ensure you get the perfect fit. The collar size you choose will be the circumference that the collar can adjust when it relaxed around your dog's neck. When tension is applied to the martingale chain it will reduce the collar's size by a max of 4". For example if you choose the 17-20" size and your pup wear's his/her collar at 18", when tension is applied to the chain it can tighten down to approximately 14". Due to the length of the martingale chain and the spaced needed for the fi device, we can't make the overall circumference of these style collars any smaller than 15”. Constructed with 1” width BioThane® & durable stainless steel hardware for long lasting performance.  100% waterproof, anti-microbial, & very durable- making them perfect for any adventure from sea to summit Adjustable Fit: By including your dog's measurements, we can create a comfortable, secure fit that's just right for them. This is especially helpful if they're between sizes or still growing, so we can make the necessary adjustments to our standard sizing. Low maintenance & cleaning is a breeze- just wash with soap and water or hose it off, & its ready for the next adventure. Reinforced with heavy duty screws at all stress points to ensure for the strongest hold. We believe screws are the most durable as the threads are tightened & reinforced to ensure your gear will never come apart These Fi 3/3+ compatible collars can be made in either the "overlay" fi style or "in-line" fi style. The overlay fi style gives your Fi device extra protection, & allows the collar to still be functional without the Fi tracker attached. The in-line fi style is where the end links are attached inline with the collar band. This is the style that comes with your standard fi collar and is the recommended fi style for the new series 3+ to ensure you get the most optimal accuracy with its additional behavior monitoring features. The Series 3+ will still work with the overlay design for GPS tracking and fitness.  Click here to add a BioThane® Leash Fi tracker is sold separately. If you don’t already have your own, purchase your tracker here.  Use our code: SEAFLOWER20 to save $20 off the activation fee from your Fi Series 3/3+ purchase.
