Always follow your veterinarian’s specific instructions. The dosage depends on your dog’s weight and the severity of the infection. A typical starting dose is 30mg/kg of sulfamethoxazole and 6mg/kg of trimethoprim, administered once or twice daily.
Example: For a 20kg dog, the daily dose would be 600mg sulfamethoxazole (800mg/160mg tablet contains 600mg sulfamethoxazole) and 120mg trimethoprim (800mg/160mg tablet contains 120mg trimethoprim). You might administer one tablet twice a day or half a tablet four times a day. Always double-check your calculations.
Administer the tablets orally. You can hide the tablet in food if your dog is reluctant to take it directly. Make sure your dog consumes the entire dose. Ensure consistent administration throughout the prescribed duration. Interrupting treatment prematurely can lead to treatment failure.
Monitoring is key. Observe your dog for any adverse reactions, such as vomiting, diarrhea, or loss of appetite. Report any unusual symptoms to your veterinarian immediately. Regular blood tests may be necessary to check for potential side effects, particularly with prolonged treatment.

They will help determine the correct dosage, frequency, and duration of treatment based on your dog’s individual needs and health status.
