Now that summer is officially here you should observe some caution with sidewalks or pavement. These surfaces get VERY hot! Hold your hand on the surface to feel what your dog feels on his paws. Try to limit your dogs contact with pavement. Even pavement that is in the shade can still be hot and metal objects like manhole covers can be unbearable.
When the weather is hot, limit your outdoor activities like walking or playing to the early part of the day or in the evening. If you can walk on the grass, do it! Be sure to bring along water for your dog to drink.
If you can’t avoid concrete and there are no shady areas around, consider carrying one or two wet towels in a baggie so that your dog can stand on them while you pick up waste or while you are unloading the car. You can also consider doggie booties. They will protect the feet from hot surfaces. However, since dogs cool themselves through the pads of their feet, booties can limit this and cause your dog to overheat.
If it's too hot for you, it's too hot for your dog!
