Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Kaiya. Poor girl. Blood in the poop can be caused by intestinal worms, a stomach illness, sudden change in diet, eating something rotten, a foreign body, or a severe illness like parvo. Because poop in the poop can have some very serious causes and it's been going on for a few days, it's time to see the vet. The vet can diagnose what is causing it and can treat her. I hope this helps!

    You should be very worried as this is usually the first sign of parvo infection. it could also be a bacterial gastrointestinal infection but either way this is something that needs to be treated by a vet ASAP.

    Your puppies need to be examined by the veterinarian. Pooping blood is always a concern and a sign of disease and inflammation. There could be many potential causes. Because these puppies are so young, they need medical intervention earlier than adult dogs. Have them seen with in the next 24 hours. Make sure to bring in a stool sample for testing. Best of luck.

Our 6 month old puppy has had a few runny poops in the last day and today there was a drop of blood in his otherwise normal looking poop. Should we be concerned? No other health issues, neutered and fully vaccinated.
Thank you for contact Boop by Petco with your question. Luke's runny poop could be caused by intestinal worms (if he's not up to date with his deworming treatments), or it could be a GI illness or he ate something rotten. The drop of blood in his poop could due to to irritation of the GI tract from the diarrhea. Since's his poop is normal now, just keep an eye on him for now. If you keep seeing blood in his poop or he has runny poops, I'd take him into the vet. I hope this helps!

My puppy is almost 2 months old, he is energetic and enjoying his new home. The pup is also eating well however there is blood in his stools and the stools are also generally very watery.
Hello and thank you for contacting Boop by Petco. Blood in the stools in a puppy usually is caused by intestinal worms or infections. Please, take Rex to your local vets to check him over. He may just need worming medication and a few days of antibiotics, but your vet also may want to test him for parvovirosis, a nasty viral infection that attacks mainly puppies.

hi I recently got a puppy and she has regular poop but then sometimes its gooey and looks like it has blood in it. i took her out this morning she ate grass then came back in and pooped it was grey and watery and it had red in it.
The most common reason that we will see soft stool (with or without blood or mucous in it) in a puppy is some type of intestinal parasite. You didn't mention how old Ivy is or if your vet has checked a stool sample, but puppies can commonly have intestinal parasites. Some are microscopic, so the only way to know that they have them is for your vet to look under the microscope. And even if a puppy has been dewormed, it is common for them to have other intestinal parasites since there are no many different types of parasites and they each require a specific type of deworming. So, my first recommendation is to have your veterinarian do a fecal check on Ivy, then decide on an other treatment. Sometimes puppies need a probiotic for their intestinal tract depending on their age and diet history, so be sure to talk to your veterinarian about that as well. Good luck! I hope that was helpful. Thanks for using Boop by Petco.

This sounds like she may have intestinal worms. I recommend using a puppy deworming treatment dosed carefully for her weight and repeated as per directions. A probiotic is also recommended to promote recovery. If she develops a fever or loss of appetite she must be seen by your vet

Thank you for using Boop by Petco! It looks like Amore has blood and mucus in her stool. This can be a sign of intestinal parasites, a viral infection, or a foreign body obstruction. I recommend that she is seen by a vet as soon as possible - sooner than the 13th would be best. You should bring a sample of Amore's stool with you in a disposable container to allow your vet to check the stool for evidence of parasites. I am happy to answer any other questions you may have and hope this helps!

My dog just pooped and it's covered in mucus (photo attached) this morning he pooped very dark poop (photo attached, has been sitting for several hours). He's had problems with bloody poop in the past, but vets didn't find a diagnosis. Is it urgent t
Thank you for submitting your question regarding Kai. Mucus covering the stool typically indicates inflammation in the colon. This is not normal. If she is eating, drinking and acting normal, then it is not likely necessary to seek emergency veterinary care. If she starts acting ill or you see obvious blood in her stool, then she should be seen. Otherwise, I would see her veterinarian again or seek a second opinion. It is not normal for her to have ongoing GI issues. There are a variety of fecal and blood tests that can be used to help reach a diagnosis. A diet trial could also be beneficial. I hope this information helps and I am available if you wish to do a consultation.

My puppy has blood in his diarrhea. It happened an hour before. He look like something definitely bothers him. Before 11PM he was fine
Thank you for contacting Boop by Petco with your question about Waffle and for providing a picture, it's very helpful. This blood in his diarrhea could be due to intestinal worms, eating something rotten, a foreign body, parvo if he isn't vaccinated, or a severe stomach illness. He should definitely see a vet for this. As long as he is otherwise ok, it can wait until the morning. If he starts vomiting, has more bloody diarrhea, is very lethargic, stops drinking water, or is vomiting water, take him into an ER vet immediately. I hope this helps!

Hi! We purchased Missy Saturday June 3rd from All Pets Club in Meriden, CT. She has been doing great House training so far, but I noticed from one of her poop accidents that it looks a bit runny, bloody, and has some mucus. Her first vet appointment
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.

Please see my dog's poop from last week, last 2 days ago and today. Why my dog poop like this? Should I need to go to ved now?
Yes, please take Kiwi to the veterinarian. The mucus and blood in the stool can be due to many things including parasites, inflammatory bowel disease, or from intestinal bleeding due to medications. Since Kiwi is a younger dog he should recover quickly once the reason for this diarrhea is diagnosed and treated. Kiwi may become dehydrated and anemic if this continues and he could become very weak and ill so please get him treatment soon. Thanks for using Boop by Petco to help you care for Kiwi.

Congrats on your new dog, but I'm sorry that Duke is sick! There are a couple of things this could be causing the bloody diarrhea. My first concern would be parvovirus. This is a highly contagious disease of unvaccinated dogs, and given his age, he will not be fully vaccinated. Parvo is very often deadly, and is considered a medical emergency. It could also be a change in diet, a GI illness, or intestinal parasites causing this bloody diarrhea. Due to the high risk of parvo, you need to take Duke into a vet immediately. The vet can diagnose what is causing the bloody diarrhea and can treat him for it. Good luck, I hope this helps!
