It's still very early days, so don't worry yet. Sometimes it takes a bit of time for the older dog to come around.
I worried that Juno was gonna have a freaker with Bowser when we brought him home just over a month ago. But every day they improved, and within a week they had worked out their little peking order and get along really really well.
One thing I will say, is just make sure you supervise them together. Don't allow the puppy to come and take your other dogs food or toys. Expect there to be a few scraps and yips and yaps and snaps.
How old is Lola?
Welcome to the forum, BTW.
