bunny breathing

Question
We have recently acquired a lop rabbit from another family that had to, "rid" of it.  We have been bunny owners in the past and were happy to give it(I must refer to the bunny as it as we are still unsure as to the sex...I think it's a she though  lol)  a nice new home.  Pumpkin ("her" new name) seems farily happy with us thus far...she is a very sweet and loving bun, always willing to share an hour long petting session.  I have noticed though that she gets very excited when we pick her up.  She stays very still when she is next to your body and looks comfy, but her breathing increases to a point where it seems like it should be a concern.  Sometimes when we go to put her down, no matter how slowly and gently, she panics and starts thrashing about.  Once down, she seems ok, but begins to breathe even harder.  She will then lay down on her belly and nudge her head against you so that you are covering her face (which I asumed she was doing for comfort).  But she continues to breathe really hard, and when you try to help her to feel better by stroking her, she only breathes harder still.  Are we handling her improperly?  Is she simply still to unsure of us?  We have, afterall, only had her for a week.  Is something wrong...or could her frantic episodes result in physical disaster for her (ie  herself sending herself into shock)?  I am worried about her when she breathes so hard and flops herself down on her belly (sometimes on her side).  Even once she is back in her cage, she continues to breathe really fast for a good amount of time.  Am I just worrying too much, or is something not quite right.  I was devestated when I lost my last rabbit to an unexplained death....I don't want to do that again...especially so soon.  We all love her already.  I am not sure of her age, and know nothing about her medical history...or even what type of lop bunny I have.  I simply know that somewhere down the line I had heard that it's not good when a bunny breathes so fast, and I am concerned!  I hope you can help me.  I appreciate your time and efferts.  Thanks in advance.......

Answer
I understand your concern, but from what you're describing I don't think there's much you need to be worried about.

The fact is, most rabbits are really uncomfortable with being picked up. They become stressed and respond like you're bunny is doing, with rapid breathing and fighting to get back down to the floor.

Your best bet would be to avoid picking her up as much as possible. I never pick up my rabbit, Rex, because he also panics as your bunny does (he has the same reaction to car rides, poor guy)

Good luck!
