This Quick Cooler adjustable collar provides comfortable cooling for your pet when it is hot. Place the Quick Cooler flat in cold water and allow to soak for 10 to 20 minutes, until the compartments are swollen. Remove the Quick Cooler from the water and dry the surface with a towel. The cooler is now ready for use. The Quick Cooler will remain cool for about two days. After that you can reactivate it. For extra cooling, the Quick Cooler may be placed in a plastic bag in the freezer for max. 15 minutes.
