BloomPaws specializes in designing unique, vivid, & stylish patterns that say I LOVE my dog! Bloom Paws handmade puppy martingale collars are durably constructed with weatherproof D ring, high density nylon & dirty resistant & waterproof eco canva fabric. Our soft & flexible collars are dog approved - they are super comfortable, as well as long lasting. Washable by hand or on gentle cycle, iron if you need it. The Martingale collar has two loops, the larger loop going around the dogs neck & the smaller loop with the welded D ring that attaches to the leash. When your dog pulls, the small loop tightens & creates tension, allowing you to correct your dog’s pulling without choking them. When your dog is walking nicely & isn’t pulling, the collar rests comfortably, without any tension. This collar option is recommended for pullers. Use a cloth measuring tape & measure your dog’s neck circumference. Make sure the tape is snug but not tight to be sure of a correct measurement. The dog collars’ length can be adjustable with slider, if your dogs circumference is between two sizes, Larger size would be more suitable. COLLAR WIDTH: 1.65" (4 cm) 1" (2,5 cm).
