We dont have enought power for Doge because we don't mine in other people pool's. according to this site http://bitinfocharts.com/dogecoin/ dogecoin Netwrok hashrate is about 80 000 Ghs, even if we had 1 ghs we would still be aprox 1/80 000 of the network power which wouldnt be enought do generate a new block consistently in the timeframe of coin switchs.
