Q. My Yorkie ate some toilet paper and threw up a yellow liquid could that be the result of the toilet paper
DR. MASSIMO ORIOLES, DVM, MRCVS
A. Yes, it could be, but usually yellow liquid is made only of gastric secretions.
Withhold food for the next 8-12 hours and then start feeding him again with some boiled chicken and rice every 4-6 hours in small portions for 48hrs.
If the signs persists or you notice any other sign such as more vomiting, diarrhea, lethargy, inappetence then I would recommend to take him to your veterinarian for a check up and appropriate treatment.
