Last I read, they hadn't decided for sure on that, but I'm betting the dog's fur could hold the virus long enough to pass on. They're so many ways aside from sneezing/ coughing on someone. Money? I'm going to do some "money laundering" tomorrow. The bills in my pocket will stay through the cycles of the washer. Debit cards? not all readers use chip only. How many fingers have pressed those buttons ahead of you, and wiping the card off after each use is likely to destroy it. The list goes on and on, but we do the best we can. If I could find some more sanitizing wipes, I would wipe the car key and all door handles, after leaving the market, but what about reusing those plastic/ or cloth bags? We're supposed to buy all our needs on line, but don't have a clue how many workers / delivery people handled that order. My attitude is do the best you can, don't make yourself crazy, and if you can't understand them, avoid people/ things that worry you.
