Did she go on a long walk before the bedroom incident?
How long was the walk on the trail? If cramping though I would think she would not have got up and walked more afterwards would have just laid down for you to hold her - just my take as that is what my dogs did but they may be just lazy dogs loll.
at any rate keep an eye on her
eta just saw it was a mile - and we walked ours two when they all laid down lolll
