Cause 1 of blood in stool: Puppy blood in stool may be due to parvovirus infection

The most likely cause of blood in dog stool is parvovirus. According to the data obtained from pet hospitals in my country, the most common disease is The reason is caused by parvovirus. Parvovirus usually appears in puppies that have not been vaccinated before 3 months of age.

Canine parvovirus is divided into two types: enteritis type and myocarditis type.

Parvomyocarditis type in dogs: Puppies have difficulty breathing, hyperpalpitations, pale mucous membranes, physical failure, and often sudden death.
Parvomyocarditis type in dogs: In the early stage, vomiting is usually followed by diarrhea. The feces are yellow or gray-yellow and contain a large amount of mucus and pseudomembrane.
2-3 days after illness: The feces looks like tomato juice, mixed with blood, and has a special fishy smell. Symptoms of dehydration appear. At this time, the sick dog is depressed and has no appetite.

Treatment of infected parvovirus:

1. Immune serum: Early use can improve the efficacy. , once a dog is diagnosed with this disease, other dogs should be injected with hyperimmune serum or recovered dog serum immediately. The dosage of hyperimmune serum is 0.5~1 ml/kg body weight, and the dosage of recovered dog serum is 0.5~2 ml/kg body weight, for 3 to 5 days. Hyperimmune serum can be used together with other antibacterial and anti-inflammatory drugs to improve the immune effect.
2. If a dog suffers from a lot of vomiting and diarrhea, it is easy to die from dehydration. First of all, pay attention to rehydration. If dehydration occurs before sending to the hospital, you can take oral rehydration at home. The amount of rehydration is 60 ml/ Weight in kilograms.
Advantages: Convenient, easy to absorb electrolytes and glucose.
Disadvantages: Forced infusion can sometimes lead to vomiting and foreign body pneumonia.
After sending the dog to the hospital for rehydration, the doctor will use corresponding methods to rehydrate the dog according to its dehydration, which can be divided into subcutaneous and intravenous rehydration. The clinically safe rehydration rate is 90ml per kilogram of body weight per hour for dogs and 65ml per kilogram of body weight per hour for cats.
3. Anti-bacterial and anti-inflammatory: Various broad-spectrum antibiotics can be used, but do not use them for a long time to prevent imbalance of normal intestinal flora and delay the recovery of intestinal digestive function.
4. Anti-vomiting: Reduce dehydration. For severe vomiting, 0.3-2 ml of Amor and metoclopramide (metoclopramide) can be injected intramuscularly.

Post-infection care:

1. Pay attention to keeping sick dogs warm. During diarrhea, they should stop feeding high-protein and high-fat feeds such as milk, eggs, and meat, and provide easily digestible feeds with light alkali. Reduce gastrointestinal burden and improve cure rate.
2. After a dog suffers from this disease, it should be isolated in time. The kennel and feeding equipment should be treated with 2%-4% caustic soda, 1% formalin, and 0.5% formalin.Repeated disinfection with oxyacetic acid or 5%-6% sodium hypochlorite.

Cause 2 of blood in the stool: eating indigestible or rotten food

Causes of blood in the stool due to eating indiscriminately

1. Some owners like to loosen the traction on the grass in the open space without people. Ropes allow dogs to roam freely. Under such conditions, dogs are prone to accidentally eat bottle caps, bones, discarded ham sausages, and even poisonous sausages deliberately placed by malicious people who specialize in poisoning dogs.
2. The feed is mixed with bones, meat, fish bones and other objects, which may cause obstruction when eating.
3. When the dog has the habit of breaking down the house at home, he may bite the food-flavored plastic or hard packaging and then swallow the plastic or hard packaging directly into the body. Therefore, when these things pass through the dog's intestines, , there is a high probability that it will scratch the intestinal wall, causing intestinal bleeding. The final result is that the dog's stool will also have blood stains.

Symptoms of accidental ingestion of foreign objects:

Dogs suddenly refuse to eat completely, are highly restless, straighten their heads and necks, drool a lot, choke or vomit, spit out foamy mucus and blood, and often scratch their necks with their hind limbs. may cause coughing or even suffocation. Diarrhea, and the stool is jelly-like with blood-red mucosal excrement.

Emergency treatment after accidentally ingesting a foreign body:

When it is discovered that the dog has just swallowed a foreign body, the first step is to induce vomiting:
Let the dog's head go down and its hind legs go up;

Keep the front low and the back high;

Pat the dog’s back with both hands at the same time;

Finger or other tool;

Put it into the dog’s mouth;

Press your tongue to make it vomit;

But be careful not to get bitten.
2. Concentrated salt water to induce vomiting. You can feed your dog some concentrated salt water to make it vomit.

Contents for sending the dog to the hospital for accidental ingestion of foreign objects:

After inducing vomiting, send the dog to a pet hospital. The doctor will draw blood to check for inflammation, and then take X-rays of the dog. Determine what the foreign matter in the dog's stomach is. If the image is not obvious, the dog will be given a barium meal to make the image more obvious.
After diagnosis, treatment will be carried out based on the size of the foreign body the dog swallowed and the damage to its gastrointestinal tract. If the foreign body is small, the doctor will recommend an infusion to replenish the pet with fluids and electrolytes, and wait for the dog to expel the foreign body on its own. The price is generally more than 200 per day, and it usually takes 2-3 days, and each time is around 4 hours.
If the foreign body is large, the doctor will recommend surgery to remove the foreign body by opening the intestines or stomach. The cost is about 4,000-5,000, including X-rays, surgery fees, anesthesia fees, and hospitalization fees. Postoperative care fees, nutrition fees, etc.)

Cause 3 of blood in the stool: Enteritis

Commonly referred to as enteritis, it includes the stomach, small intestine and colonA common name for inflammation.
Dogs with enteritis usually suffer from vomiting and diarrhea, which can lead to dehydration and death. When a dog suffers from vomiting and diarrhea, the top priority is to rehydrate the dog.

Symptoms of enteritis (how to identify enteritis):

1. Diarrhea is the main symptom of canine enteritis. The feces is liquid and has a foul odor. Often mixed with mucus, blood and foam.
2. Press the dog’s abdomen with your hands. The dog’s abdomen will tighten and its back will bend. This is caused by the dog’s pain.
3. When inflammation spreads to the front of the duodenum or stomach, sick dogs are often accompanied by vomiting.
4. Dogs will continue to vomit yellow-green watery substances with a small amount of foam, and the vomiting volume is large. The vomiting interval can be long or short. The dog will take the initiative to drink water after vomiting, and vomiting will occur again after drinking water.

Causes of enteritis:

1. Eating rotten or contaminated food, or accidentally eating poisonous bait, irritating drugs, foreign objects, etc.

2. Secondary to certain infectious diseases such as canine distemper, parvovirus, coronavirus disease, parasitic diseases (such as tapeworms, roundworms, hookworms, whipworms, and trichomonas), etc. In addition, pathogenic bacteria can also cause enteritis. For example: Escherichia coli, salmonella, Proteus, etc. can cause enteritis.

3. If the dog is always in a high degree of nervousness, it may easily lead to enteritis.

Prevention and treatment measures for canine enteritis:

1. First, fast the dog for 1-2 days. In order to prevent dehydration and electrolyte imbalance, the sick dog should be given fluids, including intravenous infusion of Ringer's solution. , or intravenous infusion of lactic acid compound sodium chloride solution.
2. Clean the gastrointestinal tract: laxatives (such as sodium sulfate, artificial salt) should be used orally in appropriate amounts.
3. Anti-inflammatory and antidiarrheal: use 0.1~0.5g of berberine, taken orally 3 times a day. Among the antibiotics, chlortetracycline, oxytetracycline or chloramphenicol can be used. For non-bacterial enteritis, when the accumulated feces has been basically eliminated and the feces has no sour smell, but still has severe diarrhea, astringent drugs should be given to stop diarrhea, such as activated charcoal.
4. If there are bleeding symptoms, hemostatic measures should be taken. Hemostatic sensitivity can be injected intramuscularly.
5. Antiemetic, metoclopramide, 1~2 mg/kg body weight, intramuscular injection, 2 times/day.
6. In case of parasitic enteritis, in addition to the above treatments, anthelmintic drugs should be given. See specifically ascariasis.

Cause 4 of blood in the stool: Pancreatitis

Pancreatitis may not be heard much in the pet industry. Let’s first educate ourselves about pancreatitis. The main function of the pancreas is to secrete "Pancreatin". Under normal circumstances, pancreatic enzymes are secreted in the pancreas.It is secreted and excreted into the digestive tract to be "activated" to digest food.But for some reason, pancreatic enzymes are "activated" in the pancreas and begin to digest the pancreas itself! To put it bluntly, “The pancreas eats itself”, and the result is inflammation and necrosis of the pancreas.

Symptoms of pancreatitis in dogs:

1. Stomach pain, vomiting, unexplained diarrhea and even blood in the stool. Acute vomiting, anorexia, depression, abdominal pain, and elevated body temperature occur.
2. Obvious abdominal pain. The dog likes to lie on the cool floor, but is restless and often moves around to relieve pain, showing obvious abdominal pain.

3. Occurs at the beginning of the disease. The vomitus contains food, gastric juice, bile or gastric juice. The symptoms are not relieved after vomiting.
4. 20-40% of cases show polydipsia, shortness of breath, tachycardia, dehydration, hepatomegaly, and mucosal congestion.

Treatment of pancreatitis:

1. Hospitalization is usually required and intravenous drip treatment is required. If the vomiting is severe, fasting is required.
2. If it is open pancreatitis (pulmonary fluid enters the abdominal cavity), surgical treatment is required.
3. Diet therapy: low-fat and highly digestible food should be fed, such as royal low-fat prescription food.

Pancreatitis is a disease of wealth and the key is prevention:

Pancreatitis is a common internal disease in dogs and cats. It mostly occurs in adult dogs and cats. It is mainly caused by unreasonable feed structure and excessive feeding of high-fat food. , Therefore, do not overfeed high-fat, high-protein feed, which is the most important step to prevent this disease.
