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. The runny nose may be due to something like an upper respiratory infection. I recommend that you have Cooper 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!
