My puppy has worms & loose stool. Is deworming every 2 weeks safe?

Updated On September 23rd, 2025

Pet's info: Dog | Cane Corso | Male | unneutered | 4 months and 6 days old | 54 lbs

Worm infestation is very rapid in our puppy. Symptoms of worms appear in almost every 2 weeks. He is now 4 months & 8 days old and weight is around 23 kg. We deworm him every 2 weeks because of all his symptoms like loose stool etc. Please advise whether we should deworm him right now? Or is it safe to deworm him after every 2 weeks?

Given the recurrent symptoms a fecal exam would be recommended to identify the underlying cause. There are many possible reasons for loose stools in pups including worms, giardia, food intolerance and poor digestive development. The frequency of deworming treatments depends on the product used, every 2 weeks is ok for fenbendazole products but I would be concerned about the recurrence rate at 4 months it would be unusual to have such dramatic signs. Check also that the dose rate is appropriate for his weight depending on the product you have used. A probiotic may also help restore natural gut balance and improve bowel health
