No, the main mining period is 100billion, but it then switches to a constant 10kDOGE/block to subsidise mining fees (which is why Doge is at around $0.0001 fees for each transaction rather than the $0.03 and rising that BTC has). That gives it a steadily decreasing inflation rate, of about 4-5% this year and trending towards 0 in the very long term. This is also mitigated somewhat by lost coins and those burnt to make other cryptoassets (i.e. Dogeparty)
