Give one dose per hour for 3 hours max, if it hasn’t helped by then, it most likelywon’t. As a rule you see an effect after 20-30 minutes if it’s “just” gas.

Try to make her move around. If her ears are cold, try to warm her up. 

No, ear temp doesn’t have to mean the core temp is low, but if a bunny has low temp and just lies there, lethargic, the ears will get cold, almost icy cold. If that happens, you can sit the bunny in your lap, and it will get a bit of warmth from your body but without any risk of overheating. Sometimes a poorly bun likes sitting in the human’s knee, and it also gives you the chance to gently elevate the butt, because that too helps gas escape. I’m assuming you’re familiar with the HowCast on massaging a bunny tummy, but I’m linking to it anyway in case someone else is interested. It’s really good: Massage rabbit tummy

Great that you made her hop across the room! It’s very good her tummy doesn’t feel hard. Has she eaten anything yet? Any poop?

Thank you for the update! I’m glad she’s doing better. Many continued-healing-vibes for her!
