Opal cat friendly

Opal is a loving girl that loves to be around her human companions. She is wonderful around children and isn't phased by cats.
Opal takes great pleasure in her daily walks and will sit upon crossing the road. She will sit, drop and shake hands on command.
She is not a digger or a barker, but will alert you if strangers comes up the driveway.
Opal loves to join you while watching TV at night and will find a cosy position close by.
She also travels well in the car.
Opal is currently in care with a smaller foster dog which she gets along well with, but will benefit from more socialisation as she can vocal yet not aggressive with unfamiliar dogs.
I believe Opal will be best suited with either another smaller dog or as an only dog.
It has been wonderful having this gorgeous girl stay with us.
