My dog's diarrhea & vomiting returned after switching to normal food.

Unfortunately, it is quite common for some dogs to experience GI upset ([vomiting](https://www.petcoach.co/dog/condition/vomiting-1/) or [diarrhea](https://www.petcoach.co/dog/condition/diarrhea-1/)) when switching food. As long as Bo is behaving normally otherwise, you may be able to [manage her at home](https://www.petcoach.co/article/6-things-you-can-do-at-home-if-your-pet-has-diarrhea). I recommend withholding food for 12-24 hours. Resume feeding a bland diet (boiled boneless/skinless chicken breast mixed with plain cooked white rice) in small, frequent amounts. Begin with 1 tablespoon of food every hour and gradually increase the amount as long as she doesn't vomit. Feed the bland diet until the stool is consistently normal (usually several days), then transition slowly to the new diet over another 5-7 days. [Veterinary probiotics](https://www.petcoach.co/article/probiotics-and-prebiotics-bacteria-aren-t-all-bad) may be considered to promote gut health. If she continues to vomit and have diarrhea, or develops lethargy, loss of appetite, or abdominal pain in spite of a bland diet, she will need to see a vet as soon as possible.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. I would recommend initiating a bland diet as outlined below. As long as she is not lethargic then this is fine to monitor for at least 24 to 48 hours. If there is no improvement or the symptoms worsen then I would recommend having a veterinarian examine her so that the most appropriate Diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction. Please let me know if you have any further questions or concerns and I will 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, thanks for using Petco Pet Education Center, formerly Petcoach! If the diarrhea only comes back when you start adding the Purina One Smart Blend in to the i/d then I would change foods. It sounds as though she has developed a sensitivity to that food or the protein in the food. If the Purina is chicken based try to get a formula with out chicken. Otherwise be sure you check a fecal and even consider deworming her (even if sample is negative), run general blood work to be sure nothing systemic is going on. Hill's i/d is a balanced diet and can be fed long term, worse case scenario. Personally I think it might be the Purina One formula, so I would try a different brand or different Purina one protein source. I hope this helps and I wish Maci the best!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Dorie! Yes, I think that is a good idea to go back to the original food and see if that stops the vomiting. Then after she stops vomiting for a week, try a different brand of adult food and very slowly transition her. If she keeps vomiting despite going back to the puppy food I would have her seen. Other causes can be: intestinal parasites, viral or bacterial infections, foreign body (something is causing a blockage), pancreatitis, intestinal disease, metabolic disease (kidney or liver problem). I wish you and Dorie the best!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Cloey! When it comes to dog food I'm in the camp that "if it's not broken , why fix it?" So for Cloey, if she as doing well, not vomiting, diarrhea, her weight is good and she liked the Pure Balance then I think it is fine for her. It is definitely likely that changing her food abruptly has caused the diarrhea, that is a a very common cause of an upset stomach. I would feed her a bland diet of boiled chicken and beef with rice until the stool is normal. Then I would put her back on her old dog food. I hope this helps and I wish Cloey the very best!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. This may be a dietary indiscretion. I would recommend transitioning her to a different food and consider adding in a probiotic such as Purina Fortiflora. I would try 2-3 different foods and see if that makes a difference. If there is no improvement, then I would recommend having her examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction. Please let me know if you have any further questions or concerns and I would be more than happy to help you further.

Hello. I am so sorry that Cleo has been vomiting. Vomiting can be caused by dietary indiscretion ( getting into the garbage ), a bacterial infection, an intestinal blockage from ingesting something, or a virus like Parvo. If she is eating, then feeding small amounts of a bland diet made up of boiled chicken & plain white rice might correct her upset. But if she refuses food &/or has diarrhea, then she really needs to be seen by a veterinarian. A puppy this young can become dehydrated in as little as a day & that will be very dangerous to her overall health. I hope she is doing better soon & thanks for using Petco Pet Education Center, formerly Petcoach.
