Another "belated" update. I got the culture results back last week. Nothing grown after 48 hours.... The vets think because he was already on antibiotics this is why got this result. Which means the med was probably working. In hindsight, should have really got culture done when he went under GA for the xrays. Least then have more clue of what bacteria is present. Ironically, had I done this thru my own vet, they would have done cleaned out the abscess at the time and sent of for culture... Oh well.

So we decided to try Jelly on Pen G Procaine now for 6wks. Still regarded as a "medium risk" antibiotic as the fortum but can be given subQ and only needed once a week. After this course we'll assess again and if any growth, stop abx and xray & do another culture.
