I finally heard back from Happi's vet. He spoke to the specialist. The specialist wants to see Happi as soon as possible but in the meanwhile, Happi has to stay immobile as possible. I have to keep her drugged and off her feet. Not easy with an active dog. The vet offered to give me some drugs to knock her out even more.
The specialist said he looked at the x-rays and he feels confident that he could be conservative and not have to do surgery and fuse Happi's bones together. He is leaning more towards splinting her leg. This is a good thing considering the situation.
Next step is making an appointment with the specialist.
