Hello,
Wow that is alot of meds. Are they diluted? Are you sure you don't mean .42ml? What is the concentration, does it have it on the bottle? At 4.2ml or 4.2cc's unless it is diluted it will overdose him with that amount.
Please recheck the dose for me. That sounds like entirely too much medication.
The benebac can be given daily, just a small pea sized amount mixed up with his food. It should really help.
Please get back with me regarding the dosage, ok? I hate for you to over medicate him. If you cannot find the concentration, please call the vet to find out what it is & make sure the dose is correct. Thanks. The bottle should say how many milligrams are in each milliliter. If not, you need to know. They need 25-50mg/kg of bodyweight.
