Hot roads and footpaths would be murder on the dog’s paws.
In addition, make sure that your dog has plenty of water and shade and soft beds at home. Whether they are a totally inside or outside dog or a dog who has access through a pet door to both, they need lots of water in a container that cannot be knocked over.
The same applies for cats.
Finally, please for heaven’s sake do not tie the dog up outside because if it gets tangled in the rope/leash it might get stuck out in the sun and die there before you get home.
