My 5-week-old puppies have diarrhea with red poop. Is it serious?

Poor pup! No, it's not normal for her to have diarrhea, especially if it's been going on for a week now. I would be concerned that she may have an intestinal parasite of some kind, or possibly an infection causing the diarrhea. I would recommend taking her to the vet today if you can for an exam - he/she can do a fecal exam to check for parasites or other problems, and will prescribe appropriate medication to treat the diarrhea depending on what is found.

Oh no, poor Sam! The red color could be blood, while the yellow could be due to irritation in his GI tract or may be pieces of a foreign body. I would have Sam seen by a vet for this problem, and bring along as sample of his feces if possible. The vet can diagnose what is causing his diarrhea and the color of his feces, and can treat him as needed. Please bring him into a vet as soon as possible since he's been having diarrhea for three days.

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. You need to take a sample of poo from several puppies to your veterinarian for a stool analysis. We usually recommend administering a deworming product to puppies starting at 2 weeks of age. This should take care of the problem. Take care.

I am sorry to hear about Shelby! It is a bit confusing reading your description because you say watery but hard poop... if you are seeing poop that is loose with red coloration to it this is concerning especially in a puppy. It is very common to have intestinal parasites in puppies and some of these can cause blood in the stool. I would make an appointment for Shelby to see a vet and bring a stool sample along with you. In the meantime you can pick up a probiotic at the pet store or vet's office to start her on in case she does have some GI upset due to an abrupt diet change. If, however, she starts vomiting or becomes lethargic, stops eating, or develops more bloody diarrhea these can be signs of parvo virus and would be considered and emergency.

Purina puppy food is fine to feed. However, I would also deworm the puppies with a puppy wormer available from your veterinarian or pet shop. If the diarrhea does not stop within the next few days, I suggest you take the litter to a veterinarian for a puppy exam and fecal exam.

This type of diarrhea could be due to G.I. parasites, which is not uncommon at all in puppies. This could also be related to the stress of a new home environment or diet change if it's occurred in the past week or so. There are over-the-counter deworming medication. However you may want to contact your veterinarian and see if they want you to bring in a fecal sample so they can tell you for sure if she has G.I. parasites. Generally speaking deworming medication it's fairly safe and would not be harmful if your puppy did not have parasites. However there are some G.I. parasites that require prescription strength deworming medication. But your veterinarian could do the fecal test and tell you if that is the case.

I am sorry to hear about your pup! In a puppy this young with these symptoms we do worry about things like intestinal parasites and parvo virus, which are not caused by milk. I would recommend having her examined by a veterinarian to check for these issues. It could also be colitis, which can be caused by a variety of things including diet changes but if it gets severe where we are seeing blood, it often does require treatment by a vet with antibiotics https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4951545
