you can try to clean up your dog

This can be a trying experience in more ways than one, if your dog isn’t fond of having her feet handled or the sound of spritzing. Nonetheless, products you might consider include:

Pet spray or wipes that are similar to hand sanitizer – you can use it on paws or all over your dog, but be aware these are really designed to remove dirt, not kill bacteria
Doggie doormats permeated with disinfectant
A foot-washing station just outside the door, with soap, a bucket of water, and a towel
Dog booties
In an earlier blog post about dealing with muddy paws, we noted that sometimes solutions that sound good at first turn out to be more hassle than they’re worth. Only you and your dog can decide. Perhaps the saner approach is to focus on house cleaning techniques that minimize potentially harmful germs. Well-known dog trainer and blogger Cesar Millan has pulled together a list of spring cleaning tips for dog owners. He also suggests more grass and better yard maintenance, to reduce indoor microbes and mess.
