The dosage of this antibiotic can usually go up to 10mg/kg (sometimes higher) but for sure not 30mg/kg as you vet directed. Also the antibiotic should be given twice daily (every 12 hours) to be fully effective. Having said that, I would recommend the extreme lethargy is not normal and I would recommend to see a new vet. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
