Welcome! My name isXXXXX am a 2003 graduate from UC Davis, and currently a Medical Director of a veterinary hospital.
I am sorry to hear about this concern for Abby.
Yes, arthritis can take a very quick toll on a pet. But! Do we think that hip is the cause of everything?
No, I don't think so.
1. She has arthritis AND some additional injury that has predisposed her to getting acutely worse.
2. She also has a spinal issue like a disc herniation that is causing deficits in her legs, and therefore, very difficult walking
and holding herself up. The "dragging" when walking is the biggest clue. Dragging, also known as knuckling, is a strong inference for a neurologic problem or disc herniation somewhere in the spine.Disc Herniation
So, I do feel this is well worth a second opinion, and if near you, a consult with a neurologist would be great. Find Various Specialists
--> Under "specialty" select SAIM = Small Animal Internal Medicine
--> Or, you can search for a Neurologist, Cardiologist or Oncologist
I hope that information has been helpful.
