Cool Vest is made with a special fabric that absorbs and retains water.  It uses no toxic chemicals or materials and requires no refrigeration.  The vest utilizes a simple scientific principle-cooling through a evaporation as water gradually transforms from a liquid state into vapor.  It takes the heat around it.    The liner is laminated so dogs don't get wet and this special fabric doesn't dry out as quickly as cotton.  On average the vest remains effective for 45 minutes to 2 hours, depending on the air temperature and humidity.  To refresh the effect, only thing you need to do is wet it again.  The sporty vest is good for all kinds of dogs from puppies to senior dogs.  It covers vital organs, providing optimum cooling effects without excessive coldness that would be harmful to a dog's health.  

Please measure your dog's Neck and Girth to determine the size you purchase. (If the size is marginal, larger size is recommended)

Preventing Heat Exhaustion in Dogs

Dogs and cats don't sweat like humans, they pant to cool themselves. Loud, rapid panting however, is one of the first signs of heat exhaustion. Other signs include rapid pulse, glazed eyes, excessive salivation, elevated body temperature, excessive whining or agitation, staring or vomiting and white or bluish gums. Only one of these symptoms has to be present to indicate your pet may be in trouble.
