Of course, Dogecoin is much more stable than Shiba, just because it has been on the market for several years longer. Shiba Inu is a classic pump & dump project with no practical usefulness. It is normal for its price to go down, unless some whale tries to pump it again.
Expecting the whales to come back to the Shiba Inu is like hoping for an uncertain luck so that it becomes empty and the whales will also become bored if their job is only to pump and dispose of them later.
However it will be difficult for Shiba inu or Dogecoin to reach the highest price,
those two coins are meme coins and I think most people already know that when a meme coin goes down it's pretty hard to get back up,
so that we can see what will happen later
the meme is for hype and trend only, nothing else nor is there anything anyone can expect from it, so if someone likes any meme for now then reconsider the decision because the risk is much bigger once it has gone downhill
