I’m old but I’ve never heard of doing that. None of my grandparents or older relatives or friends of the family ever kept matches in the bathroom. Maybe it’s a regional thing.
Our Lab always does that. If it’s raining, she does not go out and just holds it until it quits or finally has to go out, grudgingly. It’s just too funny because she’s a Labrador!
Our chocolate girl loves lettuce! She’s always at your knee if you’re making a salad. Had to move the tomato plants out of the yard because our Labs would pick the cherry tomatoes. People can’t believe she scarfs lettuce like she does.
We have a Lab that looks out and if it’s raining, she won’t go out and has been know to “hold it” until it quits or about 11:00 a.m.
