How do you cure the common cold for a puppy?
There is no cure for the common cold, which is caused by a
coronavirus or rhinovirus. As this is a viral infection,
antibiotics (which are only effective against bacteria) will not
help and can cause other problems for your puppy.
The good news is, for the most part these viruses are
self-limiting and your puppy will clear the virus within a week.
Make sure your puppy is eating and drinking normally (if nursing,
that he is still nursing well), that he is playing and exploring as
normal and that he doesn't develop vomiting or diarrhea. If any of
this doesn't happen, or your puppy doesn't start acting a lot
better within 4 days, you need to take your puppy to a veterinarian
for treatment. With severe infections, it is not uncommon for a
puppy to not drink enough fluids and get dehydrated; your
veterinarian can identify and treat this.
