Warm days shouldn't cut their walks short
Hot pavement, afternoon sun and sticky humidity can wear a pet out fast. The TailWise Dog Cooling Vest is made for summer walks, backyard play and road trips: chill the reusable cooling packs, slip them into the vest and head out together. There are no batteries, fans or cords, and nothing to plug in.
- Summer walks and backyard play
- Road trips and outdoor outings
- Made for dogs and cats

Steady cool, not ice that freezes solid
The vest holds phase-change (PCM) cooling packs. Unlike ordinary ice, phase-change material holds a steady, comfortable coolness instead of freezing solid, so it feels gentle against your pet's body. Between outings, recharge the packs in the refrigerator or a bowl of cool water and they're ready to go again.
- Steady coolness, never frozen solid
- Gentle against your pet's body
- Ready again after a quick recharge

More than a wet towel or loose ice pack
Wet towels and bandanas need re-soaking, and loose ice packs don't stay where you put them. This is a lightweight harness that holds the cooling packs against your pet's body, sized with a core and strap combination: M core with S strap for small pets, M with M for small to medium pets, and L with L for medium to large pets.
- Lightweight harness design
- Packs held in place on the body
- Three core and strap combinations
