What Pet (and Toddler) Parents Are Saying
The color is exactly like the photos and the mesh mouth means she can still pant normally on walks. Everyone we pass stops to ask about it.
Every other costume we tried covered his whole face. This one has the mesh opening so he can see and pant, and he stopped trying to pull it off within a minute.
Got the Glow-in-the-Dark Green and it genuinely glows after charging under a lamp for a bit. Our evening walks got a lot more fun.
Wasn't expecting to size one up for my 2-year-old, but the M fit her great over a onesie and she wore it all afternoon. Great matching photos with the dog.
Adjusted the hidden belly strap once and it stayed put through a whole walk. Never looked like it was choking him or about to fall off.
Plush feels soft, not scratchy, and it washed fine after he rolled around in the yard. Already thinking about which color to get next.
SEE, BREATHE, PANT (OR GIGGLE) — NO PROBLEM
The hood's mesh-lined mouth opening means whoever's wearing it — cat, dog, or toddler — can see, breathe, and make all the noise they want the whole time. No fumbling with a costume that covers the whole face, just a fit everyone actually tolerates.
ONE HIDDEN STRAP, NOTHING UP FRONT
A single strap sits underneath, out of sight — no straps, buckles, or panels across the chest or face for cats, dogs, or kids. Snug and secure without ever feeling restrictive.
SOFT PLUSH, EASY CLEANUP
The plush fabric is soft against fur (and skin), not scratchy, and it's machine washable when it inevitably gets dirty from yard time, treats, or toddler snacks. Easy on, easy off, easy to keep clean.
Dino Time, Made Simple
Measure neck-to-tail (or neck-to-back) length and choose from 6 colors, including Glow-in-the-Dark Green.
Slide the hood on and adjust the single hidden belly strap for a snug, comfortable fit.
Head out for walks, photos, or Halloween — mesh mouth opening keeps everyone comfortable the whole time.
