Midnight Stripe Dog Onesie Sweater, Cozy Stretchy Jumpsuit for Small Dogs

The Midnight Onesie Sweater from Both Tails — a stretchy striped dog onesie in moody navy and black tones, one of our top-selling pet jumpsuits. Made from soft, breathable fabric, this dog onesie keeps small and medium pups cozy on chilly walks, post-bath cuddles, and lazy fall and winter mornings.

Why dog parents love this onesie:

• Sleek midnight stripes: Deep navy and black tones with a subtle stripe — moody, modern, and impossible to dress wrong.
• Soft, stretchy fabric: Breathable enough for indoor wear, snug enough to keep your dog warm on cool walks. Anxious dogs love the gentle full-body coverage.
• Five sizes for the perfect fit: XS through XL — fits chihuahuas, dachshunds, frenchies, mini poodles, corgis, and other small to medium breeds.
• Easy on, easy off: Stretchy openings and a relaxed cut make dressing your dog quick and stress-free.

Perfect for:

• Cool-weather walks, fall and winter outings, and post-grooming warm-ups
• Anxious dogs (gentle full-body pressure has a calming effect)
• Senior dogs and short-haired breeds who get cold easily
• A thoughtful gift for any dog lover or new puppy parent
