Thanks Ladies
No mushrooms in our yard - actually - no yard! We have a cement patio, and she goes out on it into a pen.....really doesn't roam free outside much at ALL (we are probably neurotically overprotective of her - and look - she got sick anyway!)
We have been racking our brain as to what we think it was....perhaps someone had put fertilizer on their lawn, and on the walk with the dog walker, she got into it on her paws?? Just so not sure of what happened...............
