Yes, I think you have a little jealousy problem.
I wouldn't worry too much. Soon they will be
best friends. Duffy is not sure yet if she is there
for a visit, or a new life time friend. We have a
Rottie named Mandy, she plays with Princess everyday.
She also out weighs Princess by 100 pounds,
But they are best friends, and look out for each other.
It will take about two weeks to adjust, but I'm sure
you will see big changes in both of them.
