Does your dog need additional space while walking? Do they get nervous when hiking and you want to alert other dog owners to not approach without asking? Tie a yellow bandanna around your dog’s neck, harness, or leash to alert others to your dogs’ needs. Bandannas are also great for spraying with all natural tick spray and keeping bugs away from your dog’s face. 100% cotton. Help us spread the word about D.I.N.O.S (Dogs In Need Of Space)!
