Like most de-wormers, Sentry HC WormX Plus De-Wormer for Small Dogs can begin working within the first 24-72 hours following the first dose. This can vary so we suggest consulting with your vet on the amount of doses needed for your dogs based on the individual situation.
We would advise contacting the manufacturer directly for information or guidance on giving Sentry HC Worm X Plus 7 Way De-Wormer for Puppies and Small Dogs to puppies less than 12 weeks old as we can only advise per the product label.
