Dogecoin DOGE Mining Roi Calculator
Doesn't say what your hashpower is, but at 400 doge/day, I'd assume two Gridseeds? I just checked my stats, and Litecoinpool is paying ~ 0.045 LTC a day for my six Gridseeds. Which is 1200 doge or about 19¢. Leaving aside power costs (I use my miners to help heat the room), at $20 each, that's $120, plus power supplies, powered USB hub and cables, call it $150.

Oh, and something to control them, a PC or a Pi. Auto Syscoin SYS Miner. At $1/week, give or take, that's three years for ROI.
Not counting the upcoming halvening, or any hardware failures. Its not economical.
Seriously, you can do better than that on Linkslap, and much better trading. I have one of these: Which does hash at about the advertised 1. Dash DASH Cash Mining Program. 3mh/s I bought it for about 50USD over a year ago. It included all the necessary cables and such. My expected ROI at the time was about 180 days done with some calculator. His question was, is dogecoin mining profitable which the correct equipment. The answer is yes from what data i have. You seem to be addressing the question 'is dogecoin mining the most efficient use of my time and money if i want to turn a profit'.
Which obviously the answer to that is no. But again, not really his question • • • • •.
