I'm so glad Daisy is ok!! I would have been so scared too!!
When I scoop the yard, which is daily during the warm months, I always look for stuff too. When our deck was being built, I was a nutcase about checking for nails and stuff. My husband said the guy who was building it was very meticulous about cleaning up, so not to worry (what????), but I did find a few stray nails

Please give Daisy a few gentle hugs from me.
