Last week one of our two labs had diarrhea, our thought was that they were overeating (we have since removed the automatic feeder) and not drinking enough water. Now the one lab no longer has diarrhea, but the other does. I came home today, thinking I could smell an accident.. but instead she held it and was just farting! She immediately went outside and relieved herself.
Other than the diarrhea she seems to be acting like her normal self. Could this be some kind of virus that passed on to one another?
How long should I wait before contacting the vet? Or what serious symptoms should I look for?
