I’m wondering if anyone has combined the official Doggie Dooley and the DIY version. I live in Florida, where the soil is sandy, and I worry that the hole might collapse. I’ve been thinking of installing a bucket or drum, complete with drilled holes and cut-off bottom, underneath the Dooley. I’d love someone’s opinion on this strategy. DD themselves suggest a pvc pipe underneath, but I feel that’s too narrow. Thoughts?
