Hello. I am reviewing your question now.
Hello, well it is not an emergency, however:
A runny nose, whether clear discharge or not, can still be an indication for a upper respiratory infection.
So, I would also continue to monitor for any sneezing or coughing fits and/or eye discharge.
With allergies, I assume your vet has addressed that, but you can give a little benadryl, which might help a bit.
Benadryl can be given at a dose of 1mg per pound of body weight. Keep in mind, Benadryl tablets and liquids come in different sizes. So, an approximately 25 pound dog can get a full 25mg tablet or a half of a 50mg tablet. I usually avoid the liquid Benadryl in larger dogs (you would have to give too much of it). You can give Benadryl every 8-12 hours. Benadryl can sometimes be a bit sedating, so keep that in mind.
If the nasal discharge ever turns brown, green, or bloody, definitely get into a vet.
