Sorry for late update. We followed advice and took both pets in. Elvis had progressed to bloody diarrhea and they we were unable to provide vet with a sufficient stool sample. They prescribed them an anti nausea and an anti diarrhea medicine and told us to keep them off all solid food for 24 hours and just give them diluted chicken broth (I made my own so I would know exactly what was in it) and plenty of water. We are just supposed to keep an eye on them and try to get a stool sample if possible. They thought maybe colitis but weren't sure since they were both sick. Gracie is 3 and Elvis is 7. Thanks again for all the advice! On a side note we also found out that Elvis had a yeast infection in his ear. He had been itching them a lot lately. He got some ear cleaner and ointment so hopefully it clears up! Hoping they are back to normal soon. Thanks
