Originally posted by Moon Valley Canine Training [1] in Sonoma, CA, this handy tip tells you exactly how to know when the ground is too hot for your pup's feet. If you can't hold your hand on the pavement for at least five seconds, you can be sure your dog won't be able to handle walking on it. Instead, play with him inside and be sure to give him plenty of cooling treats [2] to beat the heat!
