How to Fit and Use the Swamp Cooler Cooling Dog Vest

Quick answer

To fit and use the Swamp Cooler Cooling Dog Vest, measure your dog's girth and length, choose the correct size, wet the vest thoroughly, wring out excess water, and put it on snugly but not tightly. Re-wet as needed during hot walks.

Step-by-step: Fitting and using the Swamp Cooler Vest

1. Measure your dog for the correct size: Use a flexible tape to measure your dog's girth (around the widest part of the ribcage, just behind the front legs) and length (from the base of the neck to the base of the tail). Compare these measurements to the Ruffwear size chart for the Swamp Cooler Vest. The vest should fit snugly but not restrict breathing or movement. Common mistake: relying on weight alone. Girth and length measurements are more reliable because dog body shapes vary.
2. Wet the vest thoroughly before use: Submerge the vest in cool water or run it under a faucet until the fabric is fully saturated. Gently squeeze or wring out excess water so it's damp, not dripping. The vest's outer fabric absorbs water and holds it for slow evaporation. Checkpoint: if the vest is only lightly misted, the cooling effect will be weak and short-lived. Full saturation gives the best performance.
3. Put the vest on your dog and adjust the fit: Place the vest on your dog's back, then fasten the belly straps. Adjust the straps so the vest is snug but not tight—you should be able to slide two fingers between the vest and your dog's body. Ensure the vest does not rub under the armpits or chafe the neck. Common mistake: overtightening. A too-tight vest can restrict breathing and cause discomfort. Check the fit after a few minutes of activity.
4. Re-wet the vest during long walks: As the vest dries out, the cooling effect diminishes. Carry a water bottle or dip the vest in a stream, lake, or water fountain to re-saturate it. In dry, breezy conditions, the vest may dry faster and need more frequent re-wetting. Checkpoint: if the vest feels dry to the touch, it's time to re-wet. The fabric will feel cool when wet and warm when dry.
5. Clean and dry the vest after use: Rinse the vest with fresh water after each use to remove dirt, salt, and debris. Hang it to air dry away from direct heat. Do not machine wash or use fabric softeners, as they can reduce the fabric's ability to absorb water and cool effectively. Common mistake: storing the vest while still damp. Always dry it completely to prevent mildew and odors.

Product facts

• Swamp Cooler™ Cooling Dog Vest: The light-colored fabric reflects solar radiation, while wetting the vest activates Swamp Cooler Tech for evaporative cooling. This means the vest works best when wet and in moving air; the light color also helps by not absorbing as much heat from the sun.
