Love your photos!
Your hibiscus story reminds me of the year we planted strawberries in a whiskey barrel. I was bummed they weren't growing... Until I spotted my German Shepherd spending a lot of time around the barrel. She'd been eating all the strawberries, LOL.
She's the same dog (the female in the first pic in the OP) who, one day while we were swimming in the ocean, I started noticing hard candies - still wrapped - floating around in the water. Yup, you got it. She'd been gulping seawater and - oops - it came out the other end. (Good thing nobody else was around.

) Apparently she'd gotten into the hard candies that morning, until then I hadn't even noticed it.
