My puppy has diarrhea with mucus. Is it worms? Should I go to the vet?

Updated On September 23rd, 2025

Pet's info: Dog | Chihuahua | Female | spayed | 11 months and 22 days old | 8 lbs

My puppy has had diarrhea for about 2 days now but last night it became more consistent. Her poop is very runny and sometimes even has a mucus/plastic-like cast around it. Should I be worried? What treatment can I give her or should I take her to the Vet?

The number one reason for puppies to have diarrhea with mucus around it is intestinal parasites (worms). It is best to take her to the vet for an exam so they can run a fecal test and then treat her accordingly.

    Many types of intestinal parasites, including worms, can cause diarrhea so a stool sample exam would be a very good idea. Often times feeding a bland diet such as boiled chicken and rice can help improve diarrhea. If she is not improving, if she has blood or mucus in the stool, or if she starts vomiting or not eating then she should be evaluated by your veterinarian as soon as possible. Best of luck and thank you for using Pet Coach.

    Thank you for submitting your question regarding Oreo. I would recommend that he sees his veterinarian if his symptoms persist. Being such a small breed dog, it will be easy for him to become dehydrated if the diarrhea continues. Common causes of diarrhea in puppies include parasites, bacterial or viral infections or something in the diet not agreeing with him. His veterinarian will likely run fecal tests and prescribe medication for him. In the meantime, encourage him to drink plenty of water. Feed him small amounts of his dog food. Do not give any treats. I hope this information helps!
