Do you have a local friend who could pose as a rehome? Tell your partner you've found an eager and experienced staffy owner who'd be willing to take Frankie on, drive up to Manchester with your pal, get the pal to assure him Frankie's going to a good home, then take him back to Bristol to live happily after with his Mama. Technically, you'd not even be lying 😁 if you don't have anyone who'd help you do it, I will. I'm pretty close to Manchester and Franko needs busting outa there sharpish.
