I understand that Bitcoin is the gold and Litecoin is the silver but what is Dogecoin really? I mean it started as a joke and yet people are using it even though the development is pretty much dead and seeing services starting to support it now make me question their credibility or even their sanity...
As for the market response then I honestly can't see anything. If you see the charts in CoinMarketCap for example and compare it with the time Coinbase did the announcement, there has been basically no significant changes, anything before Coinbase's announcement should not be considered as any type of "response".
I agree with you that the dogecoin is more like a joke because it was just created for fun, but one thing you should check in a coin to know if there is going to be an increase in price or not is the market volume, since dogecoin was one of the first coin in existence, it has a large market volume and that way, whales will be very much interested in buying so much of the coin in order for them to make profit in a future date.
