My dog Daisy has diarrhea the running kind. A couple times she’s had a White mucus mixed in with her diarrhea. And my question is why and what is that? Is that something I should be concerned about? And at what point do I know if she needs to go to the vet or is there more that I need to be cautious of?

Poor Daisy. The white mucus can be caused by inflammation of the large intestine. If she has been having diarrhea for more than 24 hours, then it's time to have her seen by a vet. Should it be less than 24 hours, I can give you a home remedy for her. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the diarrhea continues on the bland diet, she starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away. Best of luck.
