What do you call a dog with cold?

There isn't a specific, widely used term for a dog with a cold. However, you could describe them as having:

* A cold: This is the most straightforward way to describe it.

* A sniffle: This indicates a runny nose, a common symptom of a cold.

* A cough: If the dog has a cough, you can mention that.

* A respiratory infection: This is a more clinical term, which you might use when talking to a veterinarian.

It's important to note that dogs can't catch human colds (although they can get their own versions of the common cold). If your dog seems unwell, it's best to consult a veterinarian.
