How Much Cough Medicine Can You Give To A 4 Pound Puppy?

You don't usually. Is more likely to cause problems than to help. Could lead to poisoning, emergency, death, pneumonia ect (as can lack of treatment). Your pup is likely to need antibiotics prescribed by your vet if not on them yet and also don't ever give anything without consulting and being prescribed by the vet. Things like this and accidental ingestion of our meds are the number one cause of poisoning deaths in our pets and also high up in lists of common cause of death. If you've seen them already you can probably just call and see if doing anything else is warranted or even advisable (like in the case of danger of tracheal collapse) and if so they will tell you exactly how much you can give for your specific pup and problem.
