You do not need a $90 cooling bed to keep your dog comfortable. Here are 5 budget DIY tactics that actually work, plus 5 mistakes to skip.
This page is for general info, not veterinary advice. Call your vet for any health concern.
Tactic 1: Shallow Kiddie Pool
A 4 to 6 inch deep plastic kiddie pool is the best backyard cooling setup. Fill with cool tap water (not ice water). Place in a shaded spot. Most dogs will splash, stand, or lie in the water on their own.
The water pulls heat off the belly and paws fast. The AKC lists kiddie pools as a top hot weather tactic.
Supervise small dogs and puppies. Even a few inches of water is a drowning risk for tiny breeds. Drain the pool when not in use.
Tactic 2: Frozen Broth Cubes and Stuffed Kongs
Freeze low sodium chicken broth or beef broth in ice cube trays. Add a few cubes to the water bowl for a slow melting treat. Or pop one or two cubes directly as a snack.
For a longer chew, stuff a Kong toy with xylitol free peanut butter and freeze overnight. The dog spends 20 to 30 minutes working the frozen treat out, which cools from the inside.
Important: Use xylitol free peanut butter only. Xylitol is a sugar substitute that is highly toxic to dogs. The AVMA lists xylitol as a top pet toxin. Check the ingredient label every time.
Tactic 3: Box Fan Plus Frozen Water Bottle (Poor Man AC)
Fill two 2 liter water bottles, leaving 2 inches of air space. Freeze solid. Place one frozen bottle in front of a box fan. The fan pulls cool air off the bottle and pushes it across the room.
One frozen bottle lasts 1 to 3 hours of cooling. Rotate bottles in and out of the freezer for a steady supply. Best for small to medium rooms with low ceilings.
Tactic 4: Wet Towel Wrap
Soak a thin cotton towel in cool tap water. Wring out so it is damp but not dripping. Drape over your dog's back and belly for 5 to 10 minutes at a time.
The wet towel pulls heat the same way a cooling vest does. Re-soak when it warms up. The AVMA lists this as a standard cooling step for overheated dogs.
Tactic 5: Cooling Vest as Backup
A wet bandana or basic cooling vest works as a backup for walks and outdoor errands. Soak in cool tap water, wring out, snap on. Cools the neck and chest for 2 to 4 hours in dry heat.

What NOT to Do
- 1. No ice water bath. Rapid cooling can shock the system. AVMA and ACVECC both warn against this. Use cool tap water (60 to 70 F) instead.
- 2. No ice cubes in the water bowl for cold sensitive dogs. Very cold water can cause GI upset in some dogs. Stick to cool tap water.
- 3. No shaving double coated breeds. Huskies, goldens, and shepherds need the undercoat to cool. Shaving makes overheating worse.
- 4. No car with cracked windows. Interior temps hit 120 F in 30 minutes on an 85 F day. The AVMA tracks car heat dog deaths each year.
- 5. No hot pavement. If you cannot hold your hand on the pavement for 7 seconds, it is too hot for paws. Walk on grass or wait until evening.

Common Questions
Does a kiddie pool actually cool a dog?
Yes. A shallow kiddie pool with 4 to 6 inches of cool tap water lets your dog stand or lie in the water. The water pulls heat off the belly and paws fast. The American Kennel Club lists this as a top backyard cooling tactic. Place in a shaded area. Supervise small dogs and puppies, they can drown in surprisingly little water.
Can I make frozen treats for my dog at home?
Yes. Freeze low sodium chicken or beef broth in ice cube trays for daily summer treats. Stuff a Kong toy with xylitol free peanut butter and freeze overnight for a longer chew session. Avoid xylitol, it is toxic to dogs and shows up in many sugar free peanut butters. The AVMA warns about xylitol on its pet toxin page. Check labels every time.
Does a box fan and frozen water bottle work as poor man AC?
Yes for small to medium rooms. Set a box fan in a window or doorway. Place a frozen 2 liter water bottle in front of the fan. The fan pulls cool air off the bottle and pushes it across the room. The effect lasts 1 to 3 hours per frozen bottle. Rotate two bottles in and out of the freezer for steady cooling.
Is it safe to put my dog in an ice water bath?
No. Ice water bath is too cold too fast. The AVMA and the American College of Veterinary Emergency and Critical Care (ACVECC) both warn against ice baths for hot dogs. Rapid cooling can shock the system, cause shivering, and slow blood flow to the skin (which makes cooling worse). Use cool tap water, 60 to 70 degrees Fahrenheit, applied to belly, paws, and groin instead.
Can I leave my dog in the car with the windows cracked?
No. Never. The AVMA tracks dozens of car heat dog deaths each year. On an 85 degree day, the inside of a car reaches 102 degrees in 10 minutes, 120 degrees in 30 minutes, even with windows cracked. Cracking the windows does almost nothing. The only safe car cooling is AC running with you in the car.
What are the best DIY cooling tactics for a hot dog?
Top tactics, in order. One, move to AC or shade. Two, offer cool tap water (not ice water). Three, wet a towel and drape over the belly and paws. Four, run a fan across a wet dog. Five, freeze a chew toy with broth. Six, use a kiddie pool in the yard. AKC and AVMA both list these as standard prevention steps.
Can I freeze a regular bandana to cool my dog?
No. Freezing a bandana makes it stiff and uncomfortable. Soak a bandana in cool tap water instead, wring it out, and tie loose around the neck. The evaporation cools the neck just like a Ruffwear Swamp Cooler at much lower cost. Re-soak every 60 to 90 minutes.
What should I NOT do to cool my dog?
Five things to avoid. One, ice water bath (too fast). Two, ice cubes in the water bowl (too cold, can cause GI upset in some dogs). Three, shave a double coated dog like a husky or golden, the undercoat is part of the cooling system. Four, leave a dog in the car with windows cracked. Five, walk on hot pavement above 85 degrees, it burns paws. AKC and AVMA back all five of these warnings.
