Difference Between Dog Gastroenteritis and Parvovirus:
At the onset of the illness, the affected dog may exhibit a decrease in appetite, a lack of energy, and intermittent, frequent vomiting, with the vomit containing a certain amount of mucus. As the disease progresses, the dog may refuse to eat, with the oral mucosa becoming congested, dry, and hot. The dog's spirit is low, the abdomen is contracted, and diarrhea sets in, resulting in the passage of dark, watery stools. The urine becomes scarce and highly concentrated, and in severe cases, blood in the stool may appear. In the later stages, severe dehydration may occur, leading to significant weight loss, sunken eyes, elevated body temperature, rapid heart rate, labored breathing, and matted fur.
This condition is not contagious and can affect dogs of all ages. It is often caused by the consumption of decayed or indigestible food, or by the misuse of antibiotics, which can disrupt the balance of gut flora. Clinically, deceased dogs typically appear emaciated, dehydrated, with skin that lacks elasticity, bluetinged mucous membranes, and sunken eyes. Upon postmortem examination, the gastrointestinal mucosa may appear congested and bruised, with mucosal sloughing, reduced intestinal content, and a strong, acidic odor. The gastrointestinal tract is filled with a large amount of mucus and blood, and the mucosa may hemorrhage. In severe cases, the intestinal contents may resemble a small gruel. The vital organs usually show no significant changes.
The primary treatment approach involves antibacterial and antiseptic therapy, strengthening the heart, replenishing electrolytes, preventing vomiting and diarrhea, and repairing the gastrointestinal mucosa to enhance digestion and absorption. For mild cases, a dog can be given 10,000 to 20,000 IU of streptomycin dissolved in water, which is then poured into a bowl for the dog to drink. For severe cases and those with severe dehydration, the dog should receive intramuscular injections of vitamin B complex twice daily, gentamicin 3 to 5 mL twice daily, and metoclopramide at a dose of 1.5 mg per kilogram of body weight. Additionally, a mixture of 150 to 300 mL of glucose and sodium chloride solution, 15 to 30 mL of 5% sodium bicarbonate injection, and 10 to 20 mL of 10% vitamin C injection can be administered intravenously once. Tannic acid protein, 3 to 6 grams mixed with an appropriate amount of water, can also be administered orally.
In cases of bleeding, antihemorrhagic agents combined with vitamin K can be used for止血. If the body temperature rises, an injection of analgin can be administered. For dogs with severe vomiting and diarrhea, it is crucial to promptly replenish intravenous saline and electrolytes to prevent dehydration and autointoxication. Monitor the heart rate to determine if cardiac support is necessary.
Ensure that the dog's living quarters are dry, clean, and hygienic. Regularly clean and disinfect feeding utensils, and schedule regular disinfection. Feed the dog at regular intervals and avoid overly cold or hot food. Promptly remove feces and food from the kennel and regularly spray the kennel and floors with a specific disinfectant. Provide clean drinking water, prevent the dog from drinking contaminated water, and during winter, offer warm water to protect the gastrointestinal tract. Pay attention to insulation to maintain the dog's comfort. Use antibiotics judiciously to avoid disrupting the normal flora within the dog's body and to prevent the development of drug resistance. Regularly deworm the dog.
