I have a Doggie Dooley. I too have clay soil. At first, it worked well. Then about a month or so later, I notice the waste was just sitting in there. I thought I didnt dig the hole deeper enough. But reading your emails, it just dont work. I even add lime, along with the Terminator stuff hoping to dissolve the waste. Yeah right, it dissolves alright, and stays right there. Oh, dont let it poured down rain, then Im afraid it may overflow. Back to garbage bags.
