Years ago they had adopted a rescued male greyhound named Waldo, who when they lived in Colorado Sandy trained to be a Nursing Home Pet Visitor.
He died eventually of old age, and in South Florida, they acquired another "reject" - a sweet one just like yours, they named Jenny!
Now that they are in their new home and a tall fence installed in the backyard, they're going to get a companion for her...
Blessings to you and your Mum amd Dad, dear friend in England...
