BowTies are the perfect accessory for any occasion! Please note our sequin BowTies are more delicate than our fabric BowTies so please treat them as a special occasion accessory; they will not hold up well to rambunctious play or scratching. Our model below is a 12 pound Italian Greyhound. Our sequin BowTies measure approximately 4.5" x 4" (Christmas Sequin Color Flip measures approximately 3.5" x 3") and attach to your dogs' collar with a velcro strap. They can attach to any collar 3/8" up to 1", any style (side release, buckle, martingale, combo, hound). You can cut the velcro strap if needed for smaller width collars; it will not fray.
