I know how you feel.
I have had my cross breed bitch for 10 years (shes 13 yo) and brought my yorkie pup home 7 weeks ago.
At first my older dog wouldnt even sit in the same room as the pup but things are slowly getting better.
But my older dog barks at the pup ALOT, she has never actually gone for the pup but barks alot.
Things just take time, you need to let them get to know each other and form their own bond.
One day is not enough to tell... sometimes these things can take a while, Its stressful yes but it will be worth it. Good luck!
