Dogs with HGE should not be fed for the first 24 hours
Hemorrhagic gastroenteritis (HGE), also known as acute hemorrhagic diarrhea syndrome (AHDS), is a potentially life-threatening disease that can strike in otherwise healthy dogs. It is a disorder characterised by vomiting and bloody diarrhea, with other symptoms including a painful abdomen, decreased appetite, lethargy, or fever. Small dogs are particularly at risk, with certain breeds such as Yorkshire Terriers, Miniature Schnauzers, and Maltese being more commonly affected.
Due to the rapid deterioration of a dog's health from HGE, it is crucial to seek immediate veterinary treatment. The vet will typically administer large amounts of fluids through intravenous fluid therapy to combat the severe dehydration caused by the illness. Antiemetic medications may also be given to alleviate nausea. It is important to note that dogs with HGE are unlikely to eat during the acute phase of the illness. Therefore, a nasogastric tube may be inserted to deliver a liquid recovery diet until the dog starts eating on its own.
During the initial 24 hours of treatment, dogs with HGE are generally not fed and are instead given intravenous fluids and medications to address their critical health needs. This fasting period allows their stomachs to settle and helps resolve vomiting and diarrhea. In some cases, fasting may be extended if the dog is still passing blood in their stools, as advised by the veterinarian.
After the initial 24-hour fasting period, small, easily digestible meals are introduced gradually. Boiled, unseasoned chicken or hamburger and rice are commonly recommended by veterinarians as a bland diet to aid in the dog's recovery. This bland diet is typically maintained for a week or two before gradually transitioning back to the dog's regular kibble or wet food. It is important to monitor the dog's stool during this recovery period to ensure they are handling the reintroduction of food well.
The decision to withhold food for the first 24 hours in dogs with HGE is crucial to giving their digestive system a chance to recover and stabilise. The focus during this critical period is on providing aggressive fluid therapy and anti-nausea treatments to address the immediate health concerns. By withholding food, the veterinary team can also closely monitor the dog's condition and make informed decisions about the next steps in their treatment plan.

After 24 hours, dogs can be fed small, easily digestible meals
Hemorrhagic gastroenteritis (HGE), or acute hemorrhagic diarrhoea syndrome (AHDS), is a potentially life-threatening condition that can affect dogs of any breed, age, size, or gender. It is characterised by vomiting and bloody diarrhoea, and can lead to severe dehydration if left untreated. Most dogs with HGE require hospitalisation and treatment with aggressive intravenous fluid therapy to resolve their dehydration. During this time, they may not be fed for the first 24 hours until their condition improves.
The duration of the bland diet depends on the dog's recovery, but it is typically provided for about a week before gradually transitioning back to their regular kibble or wet food. It is crucial to monitor the dog's stool during this time to ensure they are handling the food well. In addition to dietary modifications, veterinarians may prescribe medications to alleviate nausea and promote healthy gut flora, such as anti-spasmodic stomach medicines and probiotics.
To prevent future occurrences of HGE, it is recommended to feed a high-quality commercial diet and refrain from giving extra foods or treats that the dog is not accustomed to. Providing a low-stress environment and using parasite preventive medications as directed by a veterinarian can also reduce the risk of HGE.

A bland diet of boiled chicken and rice is recommended
Hemorrhagic gastroenteritis (HGE), or acute hemorrhagic diarrhea syndrome (AHDS), is a potentially life-threatening disease that can affect dogs of any breed, age, size, or gender. It is characterised by vomiting and bloody diarrhoea, and can lead to severe dehydration if left untreated. Most dogs with HGE require hospitalisation and aggressive intravenous fluid therapy to resolve their dehydration.
A bland diet of boiled chicken and rice is often recommended for dogs recovering from HGE. This type of food is easy to digest and provides nutrition to the cells lining the gastrointestinal tract, helping them heal. It is important to reintroduce food slowly and to follow the veterinarian's feeding instructions. Typically, a bland diet is fed for about a week or two before gradually transitioning back to the dog's regular kibble or wet food. During this time, it is crucial to monitor the dog's stool to ensure that they are tolerating the food well.
In addition to the bland diet, it is recommended to provide small, frequent meals throughout the day. Probiotics and fibre can also be added to promote healthy gut flora and provide nutrition to the cells lining the colon. It is important to follow the veterinarian's advice on the specific diet and feeding instructions for the individual dog's needs.
After a dog has been treated for HGE, it is important to continue monitoring their stool for any signs of blood. While most dogs do not experience a second bout of HGE, it is possible for the illness to recur. If any bloody vomit or stool is observed in the future, it is crucial to contact the veterinarian immediately.
Overall, a bland diet of boiled chicken and rice is an important part of helping a dog recover from HGE. It provides easily digestible nutrition and allows the gastrointestinal tract to heal. However, it is crucial to follow the veterinarian's instructions and monitor the dog's stool to ensure a full and healthy recovery.

Dogs are discharged from hospital when eating, no longer vomiting, and producing semi-formed stool
Hemorrhagic gastroenteritis (HGE), also known as acute hemorrhagic diarrhoea syndrome (AHDS), is a potentially life-threatening disease that can affect dogs without warning. It is characterised by vomiting and bloody diarrhoea, and can lead to severe dehydration if left untreated. Most dogs with HGE will need to be hospitalised and treated with aggressive intravenous fluid therapy to resolve their dehydration. They may also be given anti-nausea medication and antibiotics.
Dogs that are hospitalised for treatment of HGE spend an average of two to three days in the hospital. They are discharged once they are eating, no longer vomiting, and producing semi-formed stool. After being discharged, dogs with HGE should be fed a bland, high-quality, and easily digestible diet. Boiled, unseasoned chicken and rice or canned pumpkin are recommended to give the dog's stomach time to repair itself. This bland diet should be provided for about one to two weeks before transitioning back to normal food.
It is important to closely monitor a dog's stool after they have been discharged from the hospital. Around 10-15% of dogs that experience HGE will have a second bout of the illness. If there is blood in the stool or vomit, contact a veterinarian immediately.
Although the exact cause of HGE is unknown, it is speculated that dietary indiscretion, such as eating non-food items or a sudden change in diet, may be contributing factors. To prevent HGE, it is recommended to feed dogs a high-quality commercial diet and refrain from giving them extra foods or treats that they are not accustomed to. Providing a low-stress environment and using parasite preventive medications as directed by a veterinarian can also help reduce the risk of HGE.

A high-quality, balanced diet is recommended to prevent HGE
Hemorrhagic gastroenteritis (HGE), also known as acute hemorrhagic diarrhea syndrome (AHDS), is a potentially life-threatening disease that can affect dogs of any breed, gender, or age. The exact cause of HGE in dogs is unknown, but it is believed to be caused by an overgrowth of a bacterium called Clostridium perfringens, which is normally found in the gut flora of a dog's colon. This overgrowth can be caused by dietary indiscretion, such as eating non-food items or different foods, a change in diet without an appropriate transition period, intestinal parasites, food poisoning, or stress. As the cause of HGE is not completely understood, it is challenging to provide definitive prevention advice. However, it is recommended to feed dogs a high-quality, balanced diet to maintain their overall health and reduce the risk of developing HGE.
A high-quality, balanced diet is crucial for preventing HGE in dogs. This type of diet provides essential nutrients that support the health of the gastrointestinal tract and help maintain a balanced gut flora. It is important to choose a diet that is appropriate for your dog's specific needs, including their breed, age, and any health considerations. Consult with your veterinarian to determine the ideal diet for your dog, as they can provide tailored advice based on their expertise and knowledge of your dog's health.
When selecting a dog food brand, look for options that offer a balanced blend of organic proteins, healthy fats, and fiber. These nutrients are essential for maintaining digestive health and promoting a balanced gut microbiome. A well-balanced diet can also help regulate your dog's weight, ensuring they maintain a healthy body condition, which is an important aspect of overall health. Additionally, a high-quality diet can provide the necessary nutrients to support a healthy immune system, which may help reduce the risk of gastrointestinal issues and other health concerns.
In addition to a high-quality, balanced diet, there are other measures you can take to promote your dog's overall health and potentially reduce the risk of HGE. Providing daily probiotics can help support digestive health and maintain a healthy gut flora. Probiotics are beneficial bacteria that can aid in digestion and nutrient absorption, and they may also help prevent the overgrowth of harmful bacteria. Reducing stress in your dog's environment is also important, as stress has been implicated in gastrointestinal issues and HGE. Try to create a low-stress environment for your dog, and if they have a sensitive gastrointestinal tract, be mindful that they may be more susceptible to the effects of stress.
Parasite prevention is another crucial aspect of maintaining your dog's health and potentially reducing the risk of HGE. Work closely with your veterinarian to determine the appropriate parasite preventive medications for your dog, and administer them as directed. By combining a high-quality, balanced diet with parasite prevention, stress reduction, and daily probiotics, you can take a comprehensive approach to supporting your dog's overall health and potentially lowering the risk of developing HGE.
