Welcome! My name isXXXXX am a UC Davis graduate, and currently, a Medical Director of a veterinary hospital.
I am sorry to hear about this concern for Baby.
Ironic, as I just rechecked a patient that had the same thing happen to her from yesterday.
It is critical to go into the vet right now. Yes, an ER visit.
My primary concern for head trauma is cerebral edema (swelling in the head) that can cause vestibular (balance) problems and can become life-threatening.
A vet will likely want to monitor her, place an intravenous catheter, and discuss the administration of some mannitol. Mannitol, is a diuretic that can help to reduce that swelling.
The difference in the pupils is no coincidence. That is called anisocoria, and supports that she did have a prominent head trauma.Aniscoria in Dogs
Very sorry to hear Baby got hurt. Well worth the ER trip.
Please let me know if there is anything I did not cover for you. I hope that information has been helpful.
