Stopped traffic. Literally.

We were trick-or-treating and three cars actually slowed down to look at my dog. One lady got out of her car to take a photo. I've never experienced anything like that with a costume.

Posted one TikTok the night I got this. Woke up to 40,000 views. My dog's account went from 300 followers to 4,000 in three days. This costume does the work.
Won the contest. Wasn't even close.

Entered our neighborhood Halloween contest. Twenty dogs. We won by a landslide. The judges said it was the most impressive costume they had ever seen.
Frequently Asked Questions
How do I know which size to order? ⌄
Measure your dog's back length (base of neck to base of tail) and chest (widest point). Match to our size chart. Gray, Pink, and White are available in S/M/L. Black, Green, and Purple are available in XL/2XL.
Is the costume comfortable for anxious dogs? ⌄
Yes. The ultra-soft plush fabric has no hard edges and no scratchy material. The lightweight construction means even anxious rescues and costume-resistant dogs tolerate it for hours without stress.
Does the glow-in-the-dark actually work? ⌄
Yes. The costume absorbs both natural daylight and indoor light, then emits a neon green glow after dark — clearly visible in nighttime photos and evening outdoor events.
What if it doesn't fit or my dog won't wear it? ⌄
You're covered by our 60-day money-back guarantee. Full refund, no questions asked. If it doesn't work for any reason, we'll make it right.
How long does shipping take? ⌄
Orders arrive within 7–12 business days. Allow 24–48 hours for processing and tracking updates.
Can I buy multiple colors? ⌄
Yes. Gray, Pink, and White are available in S/M/L. Black, Green, and Purple are available in XL/2XL. Many customers order 2–3 colors for different occasions.
