Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear that Luna is having trouble. Specifically diarrhea that is yellowish in color is often indicative of coccidia which is a parasite of the small intestine. It is possible it's something else like other parasites, dietary problem, etc. I don't know of any over the counter medicines for coccidia so you will have to consult with your vet and have Luna evaluated before they can prescribe medicine for her. They will be able to evaluate her and run a fecal exam then decide on the treatment. I hope see gets well soon.

Thanks for using Petco Pet Education Center, formerly Petcoach! Diarrhea can be observed with conditions such as colitis, gastroenteritis, dietary indiscretion, intestinal parasites, among many other possibilities. There are no general over the counter anti-diarrhea medications to use in dogs without an evaluation. I recommend that you have Cosi evaluated by your veterinarian for further assessment and treatment. They may choose to check for parasites and to start medications for diarrhea depending on the results. Good luck! Hoping for a speedy recovery!
