Get Your Dog Care Questions Answered by Experts
I am sorry to hear you are worried about your Pug. I am a veterinarian and will do my best to help.
If you check her gums, are they pink in color, or do they seem pale?
Does she have any discharge from her nose?
What pills did they send from the emergency clinic and did they help at all? Sorry for all the questions, but since I can't see and examine her or listen to her with a stethoscope, the more information I have the better I can help.
That is interesting she can breathe through her nose when she is exercising but not when at rest.
If she has nasal congestion, you can use children's decongestant nose drops, like Little Noses.
If the pills did not help, then this is not due to an infection.
Pink gums means she is getting enough air and oxygen into her lungs.
Steroids like prednisone might help, but you need to get something like that from your veterinarian.
The dark parts are probably normal pigment.
I would get drops that have a decongestant, not just saline solution.
Do not overuse the drops, 1 drop in each nostril once to twice daily
You tilt her face up, and drop one drop into each nostril.
If that does not help, I would try steroids next.
How is she doing? Can I help with or answer anything else?
How is she doing tonight?
