My dog is 12yrs old, has sever arthritis, moderate hip dysplasia and a few benign cysts over her body. Two weeks ago she was limping on her front leg and the lower part, towards her paw was swollen. I took her to the vet and her x-rays showed no injury to the site. However, one of her toes, the bone looked like cottage cheese. Since then, I have been told she has osteomyelitis, gram positive and gram negative bacterial infection. She was put on clindamycin and it wasn't working, so the vet put her on Zeniquin along with a probiotic. She has had a blood sample taken to determine if it's bacterial or fungal, definitely bacterial. She has had a cultural and sensitivity done, waiting on the results for that test. The vet doesn't think it's osteomyelitis anymore but does know it's resistant to the antibiotics given so far. Two weeks ago her swollen area was the size of a golf ball. Now after every time they open it up or exam the area, it's as big as a soft ball, her whole paw and lower part of her leg is now swollen and extremely painful. I have her on tramadol and gabapentin for pain but it's taken a major toll on her over all health. Her leg was draining clear to light red fluid from the site that the vet took samples from but after I had to take her back in today for more samples, for the culture test, it's now draining red blood, swollen twice the size it was earlier today and the vet said her temp was 103. I do and don't want to take her to another vet, as we have already spent several hundred of dollars already and I just don't want to start over with more tests from another vet. As each tests puts her through more pain. I just really would like an accurate diagnosis and treatment, so she doesn't have to go through anymore painful tests. Any advice would be greatly appreciated.
