“The Marsona pants sit nicely at the waist and don’t wrinkle much after sitting. Very easy to wear.”

You watch him lag behind on the walk.
Panting hard. Refusing to stand up.
He can't tell you he's too hot. But he is.

Soak Coolpup in water for 20 minutes, tie it around his neck, and the evaporative cooling beads inside pull heat off his body for hours. No freezer. No ice packs. Just cool relief the second it's on.
Ready to use the moment it arrives.
✓ He finally wants to walk again
Soaked once, Coolpup keeps his neck cool for up to 3 hours. No more cutting walks short because he's panting.

✓ No freezer. No prep. No mess.
Dunk it for 20 minutes, wring it out, tie it on. That's it. No ice packs to remember, no chargers, no gels.

✓ Evaporative beads do the work
Non-toxic polymer beads inside the fabric hold water and release cool as it evaporates. Safe against skin, gentle on fur.

✓ Fits small dogs to big ones
At 39 inches long, tie it snug for a corgi or loose for a retriever. One size adjusts to your dog.

✓ Re-soak and reuse all summer
When it warms up, just dip it back in water. Works day after day, walk after walk, all season long.

What you get today
Seasonal production run — once this batch sells out, restock pricing may change.
Give your dog a cooler summer today — limited seasonal stock available.
30-day at-home trial
Try Coolpup at home for 30 days. If your pet doesn't take to it or it doesn't work as expected in daily use, return it for a full refund.
How long does the cooling last?
Once fully soaked, it stays cool for about 2 to 3 hours depending on outside temperature and how active your dog is. Just re-soak to reactivate.
Will my dog be bothered by the wet feeling?
Most dogs adjust within minutes. The outer fabric feels lightly damp, not dripping, and the cool sensation usually wins them over fast.
Can I leave it on my dog all day?
It's designed for walks and outdoor time. Take it off once it dries out or when your dog is resting indoors in air conditioning.
How do I clean it?
Rinse with mild soap and cool water. Let it air dry fully before storing. Do not machine wash — it can damage the beads inside.
