Pls don't take your dogs on trails in heat and humidity

I was really surprised to hear that a poor dog had to be rescued from the local mtns as it got very sick from the heat the other day. Another dog actually died after going hiking with owners in San Diego. Being a dog owner, I know how much our pets love the outdoors, but pls leave them at home during our heat waves. http://abc7.com/pets/overheated-dog-rescued-from-hiking-trail-above-glendale/2226937/
