Can you give a dog cold medicine while they are nursing?

It is generally not recommended to give any medication (over-the-counter or prescribed) to a nursing mother without veterinary advice. This is because certain substances can pass through the mother's milk and be ingested by the puppies, potentially causing them harm.

There are also alternative methods to care for a sick or ailing dog that is nursing. For instance, providing fluids and proper nutrition, allowing proper rest, and creating a comfortable environment can sometimes be more effective and less risky than administering medications.

Consult a licensed veterinarian before giving your nursing dog any form of medication to avoid potential risks to the puppies.
