It is so hard to explain to dogs about the weather. Yesterday I got home just ahead of a severe thunderstorm and I hustled them outside to do their business before the storm arrived. But ours prefer to be 1) fed first and 2) walked rather than go to the yard, so they just stood in the yard and stared at me. Then were very unhappy about having to wait out the storm before the walk. There's just no reasoning with them.
And I love the "chickpea-sized hair" reference. My dad worked as a research meteorologist for 30+ years, and my family has unusual size references for hail. My brother coined the "bouncy-ball sized hail" when we lived in Oklahoma.
I like that one! I was watching out the window and trying to assess. At first, it would have been an exaggeration to call it pea-sized so I was trying to come up with a more appropriate description when it started growing. Soon I realized that "pea-sized" would be underselling it and that's when "chick pea" popped into my head!
Our dogs are suspicious of attempts to send them outdoors in bad weather. "You think I'm an idiot? I don't see *you* going outside in this crap." Fortunately, they are fairly flexible about changes to their routine.
