If a dog is infected with Toxoplasma gondii, it will show symptoms such as anorexia, lethargy, weakness, discharge from the eyes and nose, fever, pale membranes, difficulty breathing, bloody diarrhea and other symptoms. Some more serious dogs may also experience severe vomiting, severe fever and other symptoms. Some dogs are also infected with the chronic form: dogs show weight loss, anemia, loss of appetite, and sometimes neurological symptoms.

Methods to prevent and treat Toxoplasma gondii infection in dogs:

1. Sulfadiazine, 70~100mg/kg body weight, intramuscular injection or oral administration twice a day. A combination of trimethoprim or pyrimethamine is better.

2. Compound sulfamethoxazole tablets, 70 mg/kg body weight, 2 times per kg orally.

3. Synergized sulfadiazine-5-methoprim, 60-70 mg per kilogram of body weight, intramuscular injection once per kilogram. Similar drugs include sulfamethoxazole, sulfamethoxazole, and sulfamethoxazole. Generally, the medication needs to be taken continuously for 3-4 days. It should also be noted that this drug is only effective against free pathogens such as trophozoites, so it should be treated as early as possible in the early stages of the disease. If your dog isn't drinking much water, check for crystals in your dog's urine, so make your dog drink more water and use the same amount of sodium bicarbonate.

4. Treat seriously ill dogs through rehydration, hemostasis, diarrhea, cooling and other methods. During the treatment period, the dog can be supplemented with nutrients, regulate the gastrointestinal tract, reduce intestinal damage caused by Toxoplasma gondii, which causes diarrhea symptoms in dogs, and effectively improve the dog's appetite.

5. Do not feed dogs raw meat or raw animal offal.

6. Disinfect the kennel regularly. Use glutaraldehyde decabromomethyl solution at the foot of the slope to spray floors, fences and other places to disinfect and reduce odors. Additionally, dog food and water bowls need to be sterilized at high temperatures.

7. It is also necessary to deworm your dog regularly. If a sick dog is found, it should be isolated and treated, because the body of the sick dog needs to be buried deeply or burned.
