Arf Pets
Arf Pets pairs a non-toxic solid-gel core with a puncture-resistant nylon exterior in three large footprints, topping out at 35 by 55 inches. The brand says it cools for up to three hours, resets after 15 to 20 minutes of non-use, and needs no water, battery, refrigerator, or outlet. It provides more sprawl room than most passive mats and has a substantial retailer review sample, although its less-than-half-inch profile is firm and a determined chewer can still damage it.

K&H Pet Products
Cool Bed III combines a water-saturated Cool Core with a nylon-coated vinyl shell to create a cushioned surface without toxic gel or electricity. Small, medium, and large beds require one to six gallons and weigh about 12 to 50 pounds when full, so the product is better for an RV base camp, cabin, or home than frequent carry between trailheads. It has no listed dog-weight limit and a two-year warranty, but users must fill, burp, position, and move it carefully to avoid core damage or leakage.


The Green Pet Shop
The Cool Pet Pad uses a pressure-activated non-toxic gel that the brand says cools for up to three hours and resets after 15 to 20 minutes without use. Five size bands cover pets from under eight pounds to over 80 pounds, and the foldable wipe-clean format needs no water, power, or refrigeration. It is the clearest all-around option for indoor rooms, air-conditioned vehicles, and shaded temperature-controlled rest, but direct sun, a hot car, chewing, or punctures can make it ineffective or unsafe.

Frisco
Frisco places cooling fabric over orthopedic foam to give older dogs or pressure-sensitive pets more support than a thin gel sheet. Six crate-oriented lengths run from 24 to 54 inches; smaller versions are about two inches thick and the 36-inch and larger mats are about three inches thick. The removable cover is machine washable and the review sample is unusually large, but the foam must be spot cleaned, is not waterproof, and some public feedback describes only a mild cooling effect.

Bedsure
Bedsure uses a cool-touch breathable top, light polypropylene-cotton fill, quilt stitching, and a nonslip base in a half-inch mat that can go through a washing machine and dryer. Four sizes fit common crate and travel footprints, and the absence of gel, water, or a power supply simplifies packing and care. The tradeoff is performance: this is a passive fabric mat rather than an active gel, water-core, or ice-assisted system, so buyers should expect a lighter cooling sensation and limited cushioning.

Heeyoo
Heeyoo offers a one-inch-thick, double-sided mat with a removable washable cover and foldable format for kennel, vehicle, backyard, or shaded campsite use. The currently orderable 44-by-32-inch version provides generous space at a low listed price, while the foam can be spot cleaned separately from the cover. The product page does not quantify its Q-max value or explain the cooling mechanism in detail, and the two smaller listed sizes were unavailable when checked.
