The hype is still there, so there's a chance DOGE will hit $1 soon. But I don't think Dogecoin will be able to sustain current prices for the long term. We might see Dogecoin go all the way down to less than a cent (0.01 USD) in 5-10 years from now. It was never meant to be taken seriously, so I don't see a bright future for it. Developers must fix the "inflation" issue if they want Dogecoin to become a good store of value like Bitcoin. We'll see what happens in the future once people get bored of Dogecoin.
Nonetheless, the crypto market behaves in many strange and bizarre ways. Even the smallest cryptocurrencies had gone all the way to the moon. As long as money's flowing on the market, prices will only go higher. Demand for DOGE is currently high, so the $1 price prediction could become a reality by the end of the year. I wouldn't worry about the price, since all that matters is the real use cases of an specific cryptocurrency. Using Fiat (USD) as a unit of account for crypto, might be a bad idea in my own opinion.
