Hi! I totally understand your concern, giving the correct dose is really important, especially with small animals like guinea pigs. From what you’ve described, it sounds like your vet has already calculated the dose based on the fully diluted suspension. Make sure to double-check the math: after adding 9 ml of water to the 5 ml suspension, the concentration changes, so the 0.7 ml dose should correspond to the proper mg/kg for your guinea pig. It’s always safest to confirm with your vet or a pharmacist before giving the medication. Also, administer it slowly using a small syringe, and keep your guinea pig calm to prevent aspiration.
I’ve actually used
Zithromax for my own guinea pig as well, but I gave it in tablet form from a trusted pharmacy:

It really helped her recover quickly, and I could see a noticeable improvement in her balance and energy within a few days. Consistency and completing the full course really made the difference.
