We really haven't seen a change with the antibiotic use. He seems to be getting "used" to be off-balanced. Personality wise, he is pretty much the same. He's eating and drinking fine (still gets the drooly look while waiting for his food), and his BMs and urines have been normal. He doesn't act like a sick dog, other than the head tilt to the right, and the gait issue.
He's on Clindamycin Hydrocholoride (150 mg tabs - 3 tabs twice daily).
For those interested, here is what the small animal intern wrote in her discussion summary on Beau's discharge instructions:
"Beside the neurological signs Beau presented with, the rest of his physical exam was normal. The right head tilt and the rotational and horizontal nystagmus were suggestive of disease within the right side of the brain. The ataxia and the proprioceptive deficits in his hind legs were suggestive of a spinal cord lesion; together with the brain lesion suggest a multifocal disease process is most probable. Some of the possible causes included an inflammatory, infectious or autoimmune process. The causes may include a stroke or cancer. The recommended diagnostic procedures to rule out and potentially confirm a cause included a complete blood count with biochemistry, an analysis of the urine, thoracic radiographs, ultrasound of the abdomen, a CT scan and a cerebrospinal fluid tap. All of those diagnostic tests were performed today and all of them were within normal limits. This can rule out some of the potential causes for Beau's condition. The CT showed no evidence of a large space occupying mass and makes neoplasia less likely. Although CT is a good modality, it can miss subtle lesions in the brain, MRI would be indicated to definitively rule out changes in the brain tissue. The CSF tap was normal today; this test indicates that there is no inflammation affecting the meninges and within the fluid around the spinal cord and brain. Most of the common inflammatory conditions suspected for Beau normally have inflammatory CSF. This result may suggest that either a) Beau does not have an inflammatory process such as a steroid responsive meningitis or granulomatous meningoencephalitis (GME) or b) he has a rare form that has not affected the CSF.
It will take approx. 2-3 weeks for the infectious tigers results for Neospora and Toxoplasma to come back. We will contact you with the results as soon as we receive them. "
They then go on to say to monitor him closely for worsening of symptoms and that they are hopeful he will make a full recovery. If his condition worsens, they may need to start immunosuppressive therapy...
