The old dog who pretty much just lays around has a swollen elbow. Its unlikely to have been injured (she goes outside 3x a day to take care of business and then comes right back in). She pretty much just lays around.
She is on prednisone (15 mg) per day.
Could this be a reaction to the steroid? She's been on it since March or so but it recently got increased fro 10 mg to 15 mg (within the last 10 days).
