A friend of mine has an 11 year old male labrador, who has been suffering from a staph infection in his front paws for over a year (we suspect), confirmed past 2 months. He has been treated with antibiotics for over 2 months, and the staph infection (specifically s. auricularis) is still present according to the latest laboratory results that came out yesterday. The dog has been treated with antibiotics: Marbofloxacin for 2 weeks, Ciproflaxin for 20 days, and back on Marbofloxacin which is he is still on. Brief history: He was neutered 3 months ago after diagnosis of chronic prostatitis, which has since resolved. FHO (femoral head osteotomy) surgery last year. Also, the dog has2 bullets in his body, which were found by chanceby chance in x-rays taken 1.5 years ago. We do not know how long they have been there. He is a rescue. And lastly, just over a year ago his left front paw (which is the most painful for him) was lanced to drain a cyst. Prior to this, the dog had not suffered from any skin problems on his paws. Since this time, his paws have never been right, despite having been on these antibiotics for 2 months (which are the ones indicated by the antibiogram). Any ideas why this infection is now going away? Anything we should test for? Any help is greatly appreciated!
