My dog had diarrhea but stool has changed to a yellow or orange today after taking virbantel and endosorb last night. Is that causing it or should I seek a vet again?

We are having technical issues so unfortunately your photo didn't come through. The change in the color is most likely due to the medication and change in Zeus's diet. As long as he's feeling better and the stool is firming up I wouldn't worry about the color. Please finish the medication and gradually go back to his regular diet when the diarrhea has resolved. If they weren't able to exam a stool sample for parasites because of the diarrhea I would have one done when he is normal to make sure he does not have intestinal worms that could have contributed to the diarrhea. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Zeus.
