Aww. Well it sounds like your doing everything right. But I'd definitely try to find some allergy stuff for her. My bun is an indoor free roaming bunny too. Unfortunately I could not afford to fix him. The vet wanted $400 to neuter him. When he gets mad at me he will turn his back and ignore...
I had no idea it was different there. My lop ear is 3 years old now. I'm dealing with mites again. Having a difficult time trying to get funds to take my bun to the vet. They gave him revolution the Las time he had it. My daughter and I are the only ones that can handle him. He bites and growls...
Bun-Bun's vet used Benedryl for his sneezes and snuffles. He loves the taste of it too! He weighs 5 lbs and gives him 1 1/2 ml every 4 hours or as needed. Hope this helps your bunny.
