Now I have to say that I am extremely concerned to hear that her breathing rate is 140bpm. Normal resting rate for a dog is 20-30bpm. So, while its good that her gums are pink, I would be concerned to whether we may have respiratory distress on our hands if they are a bit lighter and she is having to breathe like this.
Otherwise, we would be wary that this increased respiration could be due to severe pain. And if she won't rise, then we'd be worried about belly pain (ie pancreatitis
, ingestion of toxins, or something sharp) or possible spinal or limb injury. If she can move her legs voluntarily, then paralysis
can be ruled out; but with all her signs we'd still be concerned that there may be a serious painful issue making her unable or unwilling to rise.
Now since this is so out of character and because that respiratory rate is much too high, I have to say this is a situation where we don't want to just monitor or try to home treat her here. It would really be best to consider having her checked at this stage by your local (or ER vet). They can assess if we do have any painful issues afoot and determine if there is any respiratory compromise (which can be related to lung, heart, and circulatory issues). Depending on their findings, she just may need pain relief, but if something is suspect in her GI, then xrays may be indicate. Or if this is a lung based issue, then we may need them to at least put her on oxygen to ease her breathing and get her more comfortable in this distressing state.
In this situation, it would be prudent to get your wee one to the emergency vet. To find your local ER veterinary clinic, you can check @ www.veccs.org/index.php?option=com_hospitals&nationid=1&Itemid=193 and @ http://www.vetlocator.com/
