Congratulations on your new home to be.
If Brinna will be staying inside the house,
I would just make sure she would be getting
plenty of daily leash walks. You can buy one
of those re-tractible leashes and take her to some
open space. If She will not be inside, can
you purchase or build a temperory GOOD size
chain link secure dog run with shelter?
It might cost you a couple of hundred to make, but
at least you will have the peace of mind that she will not run off. You will still need to take her for plenty of walks and you
can take down the dog run when you move back to your
new home.
My brother-law lives in a place where you are not allowed to
fence your property. He is on his 2nd Golden Retreiver.
She is a house dog, and he takes her for plenty of
walks and jogs with him. I would have suggested
a friends yard or a kennel but that would be to
long of a period for Brinna.
