Hi,
I feel really sorry that you were unable to be accepted for one of these three, especially as I brought them to your attention.
The garden thing was one of the most important things in my assessment from the RSPCA when we got Tia. They wanted somewhere secure to insure against wandering doggie as they didn't want to rehome the same dog twice.
Sylvia does care passionately for her dogs, and was almost trying to persuade me against Jack, I think to test my commitment (even though we'd already driven 200 miles!).
Well done for considering the journey. I had been so hopeful as I read your post. I share, in a small way, your disappointment!
Take care,
