 very clearly where are you going to be what are you going to be doing am I going to be able to get that dog to the shade keep it on the grass or have it in an air-conditioned place or not and absolutely never ever ever leave him in the car not even for a minute if you have to leave that car you need to be able to take the dog with you or your dog should be at home it's so much nicer to go home to a happy dog than to end up with a tragic situation
