I don't know which got it first, but the vet has confirmed and issued treatment for Giardia in the dog, and based on stool observations at least one of my 3 hens has it too (who are all currently being treated with metronidazole and a probiotic supplement). All 4 animals are forced to share...
I use my non-slip Crocs back from my chef days. They slide right on and hose off real easy. I'll probably get more once these finally wear out, but after 5 years of absolute abuse they're still going strong!
