If he is behaving normally otherwise and has pink gums, then you can try withholding food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet in small, frequent amounts until the stool is normal then transition slowly to the regular diet.
If symptoms persist or if, at any time, he develops lethargy, pale gums, vomiting, diarrhea, loss of appetite or abdominal pain then he should be seen by your veterinarian or at the nearest veterinary ER.
You always have the option of having him seen sooner. At best, he will get a clean bill of health and you will have peace of mind if everything checks out. Given current events, you may need to drop him off at the clinic then wait for your vet to call you to discuss exam findings and treatment options.

If she is still energetic and not vomiting, doesn't have abdominal pain, and her gums are nice and pink (versus pale) then most likely she will be ok until tomorrow though none of us can predict exactly how disease will progress. Signs she should go to the emergency vet would be pale gums, weakness/lethargy, repeated vomiting, abdominal pain, difficult breathing/excessive panting. If these occur or if she is having repeated diarrhea she should go to an emergency vet.
