Female puppy Australian shepherd/ border collie

We have one puppy left, a border collie/ Aussie puppy.
She is 7 weeks old tomorrow.
Ready to go home 1/31.
She will come with a health certificate and first vaccines from the vet.
These pups are practically potty trained already and play outside a majority of the day.
They are super smart and friendly.
Mom is a red Merle Aussie and dad is a red and white border collie.
Serious inquiries only from people who understand the exercise requirements of the breed.
Thank you!
