Vomiting in dogs with cancer is not uncommon and there are many reasons a dog might throw up after a meal. Always follow the instructions provided by your veterinarian and consult him or her with any concerns.
If you are transitioning your dog to Canine Biologics Nutrition System, we recommend transitioning your dog to the new food over a period of five days. If at any time you notice blood in your dog’s vomit or stool, or if vomiting is accompanied by diarrhea, please contact your veterinarian for guidance.
The Animal Cancer Foundation website notes “nausea may be associated with some types of cancer… Some tumors in the mouth, throat or intestinal tract may make eating, swallowing or the digestion of food difficult.” Additionally, “tumors of the digestive tract may cause vomiting…”
If your dog is receiving chemotherapy, according to the Animal Cancer Foundation website, chemotherapy drugs can cause inflammation of the mouth, tongue and esophagus. Drugs used in chemotherapy can also alter the sense of smell or taste” and can “cause nausea and/or vomiting with or without diarrhea…”
If your dog is receiving radiation therapy radiation of the chest or abdomen can affect the esophagus, stomach and intestines which may cause vomiting and/or diarrhea.
If your dog is not receiving chemotherapy or radiation therapy PetMD says many gastrointestinal upset conditions are alleviated by feeding a bland diet. You should discuss this with your veterinarian who may prescribe something for nausea or who may have additional advice. If you wish to try the bland diet, follow these veterinarian-recommended steps:
- Withhold water and food for 3–6 hours. If additional vomiting occurs, contact your veterinarian.
- If no additional vomiting has occurred, offer a few tablespoons or water or an ice cube. If no vomiting occurs, wait 30 minutes then offer a small amount of water again. This can be repeated for 2–3 hours. If there is still no vomiting after this time, you can slowly introduce a bland diet.
- To make a bland diet, boil lean chicken or hamburger. Mix it 50/50 with boiled white rice. Do not add anything else. Offer a tablespoon of the mixture. If there is no vomiting after 2 hours, offer a bit more. Gradually increase the amount and frequency. For example, instead of 2 Tbsp. every 2 hours, you can gradually increase the amount to maybe a ½ cup every 3 or 4 hours. This will differ based on the size of your pet.
If your dog is tolerating the bland diet without vomiting, you can slowly re-introduce the Canine Biologics food again over 5 days transitioning by adding approximately a fifth of the Canine Biologics Nutrition System the first day, while decreasing the bland diet by the same amount. The second day increase the Canine Biologics Nutirition System to two fifths of the meal and decrease the bland diet by the same amount and so on until your dog is completely on the Canine Biologics Nutrition System on day five. If the vomiting and/or diarrhea returns, please consult your veterinarian.
