Our Biothane martingale collars are ideal for dogs who need a touch of correction during walks, or have the tendency to back out of flat collars. 

SIZING INFO - The measurement you give, ex: 18 inches, will be the entire inner circumference of the collar when sitting relaxed, not pulled tight. Measure your dog's neck with a soft measuring tape, placing the tape around the area where your dog wears their collar, or you can take your pup's current collar off, do it up to the size where they comfortably wear it, and then measure the inside circumference with a measuring tape. It's also a good idea to try sliding the collar on and off at that size while done up, to make sure that it will fit over their head. If your pup has a wider head than neck or you prefer a looser fit, you may want to add an extra .5 to 1 inch to your measurement. If you are unsure about measuring or just want a second opinion, please send us a message! We are always happy to help you find the perfect fit.

HARDWARE - Brass hardware will create carbon over time, just like fine jewelry. This can easily be polished away with a soft cloth, but for white or light coated dogs, this carbon may give a slight grey cast to the neck fur. To avoid this, we recommend going with the nickel hardware if your dog has light fur at the neck area.
