Why is my dog not eating breakfast and throwing up foamy grass?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Kuma could be suffering from a dietary sensitivity or indiscretion. I would start by initiating a bland diet and then feed this at least 3 days beyond the resolution of the vomit. Once it is resolved, I would transition back to the dog food. If the vomiting and decreased appetite begin again, I would do the bland diet and then transition to a completely different dog food altogether and see if this helps. If this does not help, then I would have the veterinarian examine Kuma so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further. Please take the time to mark this question as helpful or not as it helps us to improve on the quality of our answers to other pet owners. Thank you kindly!

[Vomiting](https://www.petcoach.co/dog/condition/vomiting-1/) in dogs has multiple causes and can sometimes be a symptom of a greater underlying condition. In the absence of additional symptoms (lethargy, [diarrhea](https://www.petcoach.co/dog/condition/diarrhea-1/), loss of appetite, abdominal pain), most cases of vomiting can be managed at home with a bland diet fed in small frequent amounts until symptoms resolve. Gradually transition over 5-7 days to the regular diet afterwards. If vomiting persists for 24 hours or more, or if new symptoms develop, a visit to your veterinarian is recommended. That said, what you have described may be a condition known as bilious vomiting syndrome. The exact cause is unknown and it can affect dogs of any breed or age. Too long of a time between meals is thought to contribute to the condition. [Bile](https://www.petcoach.co/article/diseases-of-the-gallbladder-bile-duct-in-dogs/), which is quite irritating, may enter the empty stomach and can cause vomiting. Pet parents report a foamy, yellow vomit late at night or early in the morning. Since Tickles has been [vomiting](https://www.petcoach.co/article/how-to-deal-with-chronic-vomiting-in-dogs) so frequently, an [exam with your veterinarian](https://www.petcoach.co/article/what-does-your-veterinarian-look-for-during-a-physical-exam) would be recommended to either confirm bilious vomiting syndrome or to diagnose and treat another cause. Blood work and abdominal x-rays may be suggested after the exam. A bland diet and antacids may be dispensed. Offering a small meal just before bedtime may help as well.

There could be many things that are causing this in Loki. Less likely a foreign body especially since he bounces back right after vomiting. It can be viral related or just a gastrointestinal upset. We always are concerned about Parvo in an unvaccinated puppy since he is only 9 weeks but this is less likely if he is energetic and has no diarrhea. He can always have intestinal parasites especially in a young puppy. I would recommend a stool check, deworming, a bland diet and an antacid as long as everything else is ok.

Thank you for using Pet Coach to address your concerns. With Thor's age and these symptoms, I am concerned that there may be something going on systemically (liver disease, kidney disease, infection, etc.). With these symptoms, I would recommend having Thor examined by a veterinarian and having his blood tested to make sure his organ function is within normal limits. If you recently switched diets, this could be dietary indiscretion. If you are unable to get to your vet right away, I would recommend starting a bland diet as outlined below and adding in a probiotic such as Purina Fortiflora. 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.

Thank you for using Petco Pet Education Center, formerly Petcoach! Chronic vomiting in dogs is pretty concerning and can be caused by gastritis, ulcers, foreign body obstructions, pancreatitis, and intestinal parasites. Other internal issues, for example kidney or liver disease, can make dogs nauseous as well. Sometimes, dogs will vomit yellowish liquid if they re extremely hungry and anticipating their meal. You can try feeding Urban a little later at night to see if this helps (this only applies if he eats meals rather than picking throughout the day). I recommend having him seen by a vet to ensure that nothing serious is causing his issues, especially if you are planning a trip. I hope this helps and that all is well with Urban!

Thanks for using Petco Pet Education Center, formerly Petcoach! Vomiting can be observed with gastroenteritis, dietary indiscretion, food sensitivity, foreign body ingestion and obstruction or other conditions such as pancreatitis or kidney disease. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. Likely diagnostics to be performed include abdominal imaging and general bloodwork. Treatment would depend on findings. Good luck and have a great day!

Poor Finn! I would try to feed him a bland diet of plain boiled boneless, skinless chicken and white rice to see if this settles his tummy. If the vomiting is happening first thing in the morning before breakfast, it would be acid reflux. To remedy this you can try feeding him right before bedtime and right when you wake up. Acid reflux is from the acid building up in their stomach overnight when they go a long period without food. If these tricks don't help or he is showing any new symptoms, I would have your vet take a look at him. Your vet will be able to determine the cause and get him started on the proper meds to help him feel better. I hope this helps!
