Coccidiosis is a parasitic disease caused by coccidian protozoa that can affect the intestines of dogs, leading to diarrhea, weight loss, and general weakness. Toltrazuril is highly effective against these protozoa, providing a targeted and efficient solution for managing and eliminating coccidiosis in dogs.

How Much Toltrazuril Can I Give My Dog?

The dosage of toltrazuril for dogs depends on various factors, including the dog’s weight, the severity of the infection, and the specific product being used.

Toltrazuril targets these parasites, interrupting their life cycle and ultimately eradicating the infection.
