I know you're trying your best for Grover. I love Frenchies, lost my Boston this past Dec.

French Bulldogs are the most stolen breed right now.

Their popularity has exploded in the past 5-10 years. A man got murdered trying to sell one via craigslist in South Carolina.

I would talk to PARL. If you want, I can talk to FOHA (Friends of Homeless Animals, they specialize in smaller breeds). In either case, the adopter will pay a fee (not cheap) and by vetted. That Grover's best shot.

Sorry to be a Debbie Downer. I know your heart's in the right place.
