I've got a year old Malinois that I hope to go running with this summer. I live in Virgina where the summers are hot and humid. I've seen a number of different dog-cooling vests online, but very few reviews of them from 'real' runners. I know that K9's in Afghanistan/Iraq are equipped with cooling vests for the 120F temps they have to endure, but I'm not sure which ones or how they translate to running.
I'm not interested in the evaporative vests because they don't work when it's humid. I want one that has the cooling inserts.
Safety of the dog is the most important thing. Too hot = no run.
