Hello to both you and Rocco, I'm living in Central Florida with my boy Bubba, yes not Nevada, but as your probably aware we also get very hot in the summer. And yes I do dread summer walks a lot of the time. A couple of tips that may work for you, try walking very early and later in the evening if your schedule allows, out of the high sun when possible. I have a few parks close by that have areas where the trees act as a canopy so lots of shade to walk in, so I'll take him there (perhaps an option for you). ALWAYS, always have a couple of water bottles with you, for drinking and if he gets too hot to pour on his head to cool down. Get use to hearing him breath when he's out in the heat, you'll soon be able to tell when he's laboring, when (and if) he gets to that point cool him (water), and get him indoors. Its a fine line we walk with Bulldogs and heat , it can be dangerous (heat exhaustion, heat stroke). When walking stay off the blacktop roadway and paths, its get extremely hot, concrete surface is not as hot, much better on those puppy pads. IM looking forward to October...LOL
