Why is my dog's poop yellow after recent surgery and antibiotics?

As long as Coco is feeling well, this is likely a change in the stool from the antibiotics and maybe from anesthesia. I would recommend starting a bland diet and adding in a probiotic such as Purina Fortiflora, which can be found online or at your local Petco. For the bland diet, please see below. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further. GENERAL INFORMATION A bland diet is a diet that is soft and highly digestible. It is low in fiber, fat and protein and is high in carbohydrates. Bland diets are generally composed of a single carbohydrate source and a single lean protein source. The most common bland diet is boiled rice and boiled lean chicken breast, without skin and bones. Since bland diets are low in fiber, stool production slows and defecation is less frequent. Bland diets are fed to rest the gastric system and to help promote normal stool formation. Animals that are physically sick should not be fed bland diets as a method of treatment. PRIOR TO FEEDING A BLAND DIET Pets should be fasted for 12 to 24 hours. Young animals should not be fasted for more than 12 hours. Fasting will allow the intestinal system to relax and minimize acid secretions that may irritate and inflame the intestinal lining. During the fast small amounts of water or ice chips may be provided. Never fast a sick animal, it may cause disease progression and death. BASIC BOILED RICE AND CHICKEN BLAND DIET RECIPE CARBOHYDRATE SOURCE: Boiled white rice LEAN PROTEIN SOURCE: Chicken breast, no skin and bones BOILED RICE: 1 part white rice with 3 parts water boiled for 20 – 25 minutes or until the rice is easily crushed. BOILED CHICKEN: De-fat chicken breast and boil in water for 10 – 15 minutes or until the chicken meat is easily pulled apart and cooked all way through. MIXING INSTRUCTIONS: Finely chop the lean protein and mix 2 cups carbohydrate source and ½ cup lean protein source. STORAGE INSTRUCTIONS: Bland diets can be premade and stored in the refrigerator for a maximum of 48 hours. The bland diet can be cooked in a batch and frozen in feeding sized portions to minimize preparation time. Thaw and warm the frozen diet prior to feeding. PERMITTED LEAN PROTEIN SUBSTITUTIONS Pork loin, egg whites, low fat cottage cheese. 7% low fat hamburger, plain low fat yogurt. PERMITTED CARBOHYDRATE SUBSTITUTIONS Boiled potatoes, boiled spaghetti, Minute rice. PERMITTED COMMERCIAL BLAND DIETS Science Prescription Diet I/D, Eukanuba Veterinary Diet Low Residue, Royal Canin Veterinary Diet Intestinal HE. FEEDING INSTRUCTIONS Estimate 25% of your animal’s diet and feed that amount of the bland diet every 6 – 8 hours. Smaller animals will require less and larger animals will require more adhering to the same carbohydrate to lean protein source ratio. The bland diet should be fed for 4 -5 days with no treats or other food sources until stools are firm. TRANSITION BACK TO A NORMAL DIET Never transition back to a regular diet rapidly. Transition back to the regular diet over a 1 week period. Start by adding 25% of the regular diet to 75% of the bland diet and feed that combination for 2 days. If stools continue to be firm then continue substituting the regular diet in 25% increments and feeding the combination in 2 day time intervals until the diet is 100% regular diet. Minimize treats for 1 week after moving the diet back to 100% regular diet.

Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! It is possible it could be a side effect of the sedatives used. If you recently changed foods, that could also explain the coloring difference. Other times, it can be due to parasitic, viral, or bacterial infection present. If the yellow stool continues, you may want to have the stool tested with his veterinarian. I hope this helps!

I agree that this poop is quite a bright color yellow! This is not normally caused by metronidazole, so it's hard to say why it might be happening. Poop can sometimes be yellow or orange in color, and it may not mean anything in particular... so I wouldn't necessarily be concerned unless it stays this was for several days in a row, or she's having other symptoms of a problem. If she's still acting normal and this stool is improved vs. yesterday (which I'm assuming it is, since it definitely looks better than bloody diarrhea!) it should be okay to continue on her meds as prescribed by your vet, and monitor for the next few days. If her stool is not back to normal within the next 3-5 days, or if she develops other new symptoms in the meantime, then I would recommend having her rechecked by your veterinarian.

I'm not sure what Panda is on antibiotics for, but I'm going to assume it was for issues with pooping. If they aren't improving things yet, it's time to ring the vet again and discuss other possible causes of these issues, including intestinal parasites and food intolerance.

Hello, thank you for your question about Romeo. It is possible that the color change could be secondary to one of the medications as these can often lead to change after digestion in the GI tract. If the diarrhea continues in spite of these treatments I would recommend having Romeo rechecked by your veterinarian so that they can consider adding additional medications such as an antibiotic/anti-diarrheal such as metronidazole. Hope this helps, good luck!

The color of the stool is usually associated with something they are eating, but the yellow/orange color can sometimes be associated with liver disease. Since Marley does not seem to be responding to previous medical treatments, I would recommend that you discuss additional diagnostics with your vet. I would start with an intestinal parasite screening, and if that is negative, move on to bloodwork and/or a GI panel (specialized bloodwork). Occasionally all labs can be normal and surgical or endoscopic intestinal biopsies are needed.

Changes in stool color can happen, especially if there was a change in the diet. I would not be concerned about a one-time color change if Peggy Sue is otherwise normal. If she has a poor appetite, vomiting, or diarrhea, then she should get checked out by a vet.
