Grace's infection isn't healing well... so she needs at least 3 days in hospital again, with IV antibiotics.
We're pulling out the big guns, and the danger is there is a possibility of kidney damage. I had the option of giving her shots at home, and bringing her back in 3 day intervals for urinalysis to check kidney function, but IV meds are better for her in terms of effectiveness of the medicine and really pushing fluids to keep her kidneys working. So the smart choice is hospital stay and IVs. As far as cost goes...
It's Grace. We'll pay it. Too many good years (and puppies) ahead of her.
