My dog has yellow diarrhea for a week, home remedies not working.

Updated On September 23rd, 2025

Pet's info: Dog | Cocker Spaniel | Female | spayed | 1 year and 1 month old | 14 lbs

My 1 year old Cockapoo has now had diarrhoea for a week. On two occasions it has seemed to begin to improve but then got worse again each time. She is pooping in the house overnight but very rarely going in the day (she normally poops about 4 times a day). For the last two days she has been fed only chicken and rice and also for the last 2 days the diarrhoea has been bright yellow with lots of mucous. Previously it was darker in colour. She eats James Wellbeloved dry food and has hard stools

Poor Harper! This diarrhea could be caused by intestinal parasites, GI illness, or a foreign body. Because you have tried a bland diet and the fact that her diarrhea has been on-going for a week, she should see a vet today. The home remedy isn't working, so the vet needs to examine her to see what is causing her to continually have diarrhea. Once the cause is found, she can be treated appropriately.

    There are many possible causes for diarrhea in a dog. These can include intestinal parasites including worms but also protozoal organisms like coccidia an giardia. We can also have overgrowth of bacteria in the intestinal tract leading to diarrhea, inflammation of the colon (colitis), food sensitivity/allergy if new food or treats were given, among other things. If her energy level is good and no vomiting, you can try diet of plain white rice and boiled shredded chicken breast for a day or two. You can also start her on a probiotic for dogs. Your vet's office probably has these, as do many pet stores. The pet store or your local Tractor Supply or Farm and Home also are likely to carry an antidiarrheal medication made for pets containing kaolin and pectin such as this one: petco.com/shop/en/petcostore/product/well-and-good-dog-anti-diarrhea-liquid. If your dog becomes lethargic, starts vomiting, stops eating, or the diarrhea persists, then a vet exam is needed ASAP. It is never a bad idea to call your vet and see if they can test her stool to ensure there isn't an identifiable cause for diarrhea, such as common intestinal worms or protozoal parasites I mentioned. If she was just there recently, they may even be willing to prescribe some antidiarrheal medication for her without having to bring her in. If the diarrhea is continuing to happen pretty frequently, and there is blood or mucus present is quite possible your dog could have something like colitis: veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=677 and needs a course of antibiotics.
