The owner takes the dog to the hospital promptly to buy anti-inflammatory and antibacterial drugs for treatment. At the same time, it also needs to be treated with anti-diarrhea, replenishing water, and regulating gastrointestinal function. During the treatment period, owners need to pay attention to the dog's diet and avoid feeding greasy food to the dog.

Prevention and control measures for E. coli:

1. If a sick dog is found, it should be treated immediately. Many drugs are effective against E. coli. Commonly used drugs include sulfa drugs, chloramphenicol, garlic tincture, and other anti-inflammatory and antidiarrheal drugs.

2. For severe cases, glucose saline and sodium bicarbonate solution can be injected intravenously or intraperitoneally, and Ensure enough clean drinking water to prevent dehydration.

3. Strengthen feeding management and improve environmental sanitation. In particular, the delivery room for female dogs should be thoroughly cleaned and disinfected. If the female dog’s udder is contaminated, it should be cleaned in time.
