How Long To Continue Antibiotics?

[sandgrubber]

Molly whelped two weeks ago. About six days after whelping she got some sort of abcess in her mammary glands, accompanied with hardening of mass behind the teats and loss of appetite but not fever. The vet prescribed Amoxiclav for five days. She responded well, but it's been slow. I went back and got a script for another four days when she still had the hard lumpy htings -- though reduced in size -- after five days. At 10 days the lumps are almost entirely gone, although I can still feel one spot, presumably where the abcess was.

Question: I've been taught a rule of thumb that antibiotics should be continued for two days after the patient is asymptomatic.

Do others agree on this principle?

Does asymptomatic mean lumpyness completely gone, or appetite and energy level back to normal?
