If her fever is 104 or higher it's a medical emergency. Use cool compresses on her neck area/head, 'armpits' and thighs.
You can try to offer (unflavored) pedialyte to keep her hydrated, but most important is getting her temp down on the way to the vet where (s)he can administer fluids as necessary.
Labored breathing is another urgent care symptom.
I wouldn't delay having her seen by a vet, even if it's an emergency visit. Please
Wait - that's not a temp for a dog. Actually, it's the opposite.
Her temp should be between 100-102.5
While aspirin is fine for dogs - this size dog shouldn't have more than a 'baby aspirin' once every 12 hours unless a vet advises differently.
The non-eating, dry nose, low temp, labored breathing are still indicative of urgent care needed.
Is she at least drinking? Moving about? Has she urinated/defecated? Were they normal? Diarrhea? Strong urine or frequent urination?
Has she had her vaccinations? Is there any coughing or sneezing? Any vomiting?
You did just perfect! Not too much aspirin and a vet visit.
Thank you for being such good people to this animal. She's a very, very lucky dog!
Let me know how it turns out ok?
