My vet has recommended this dewormer so I assume it is still effective in this area. He recommended it at 10mg/kg which is double the horse dosage. I've had my goats for almost one year and this is the first time I have dewormed them and have no idea if they had been dewormed before I purchased them. How often should I repeat it? Every day for 3 days (as directed on the package for horses) or in another 10 days as I've seen mentioned on the boards?
