Poor Hugo! He could have an infection, parasite, upset stomach from something he ate, pancreatitis, liver disease, kidney disease, endocrine disease, etc. Since he isn't eating or drinking much he could become dehydrated so he really should be examined by a vet to determine the cause and treat. Your vet can run blood-work and take an x-ray, if needed, to help diagnose and then prescribe medications to treat. He might need fluids, an anti-nausea medication, antibiotic, and/or gastrointestinal protectant. Hope he feels better soon!

    Hi there and thank you for using pet coach to address your concern. I am sorry to hear chip is not feeling well. If bloodwork is normal, my next suggestion for testing would be xrays and an abdominal ultrasound. It is possible that he ate something he shouldn't have and has an obstruction in his GI tract. You can offer a bland diet and use the following guide to feed him. If he is not eating any of the bland food you cook him, I would have him looked at again and get the additional testing done to get to the bottom of this. Please let me know if you have any other questions or concerns. 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.

    He could have stomach ulcers but he could also have pancreatitis, liver/kidney disease, endocrine diseases, etc. If the blood-work comes back normal than he could have an abdominal ultrasound to look for abnormalities. You could feed him some boiled chicken and white rice and see if you can get him to eat. Hope he feels better soon!

    Hello, sorry to hear about your pup. You're describing signs of a GI upset. The hyper salivation and foaming may both be signs of nausea. The bloated abdomen may be a sign of increase gas within the GI tract. This could caused by a dysbiosis of the normal GI flora or a separate disease process such as a obstructive foreign body that is not showing up on x-rays, a stomach ulcer, a severe dietary indiscretion, or pancreatitis. Other causes such as liver disease or kidney disease should have shown up on bloodwork. I think continuing care with a specialist and pursuing further diagnostics such as an abdominal ultrasound are warranted. Hope this helps and best of luck.
