Please spread the word for this lost dog by sharing this post.

💬 Owner's Message: "🚨 MISSING / POSSIBLY LOST FRENCH BULLDOG — LAKE ST. LOUIS / ST. CHARLES COUNTY AREA 🚨

We are urgently trying to locate our dog. He is a 5-year-old male French Bulldog, approximately 27 pounds, with gray/black coloring.

He was last known to be at his home in the Lake St. Louis area, but he was removed from the home this morning and we have not been given a verifiable location for where he was taken.

Because we cannot confirm whether he was surrendered, rehomed, released, or otherwise lost, we are trying every possible avenue to locate him.

Please keep an eye out for him in the Lake St. Louis, O’Fallon, Wentzville, St. Charles, and surrounding areas.

If you have seen a French Bulldog matching this description, recently found one, or know of one being brought into a shelter or veterinary clinic, please contact me immediately."

🐾 Description: "25lb French Bulldog, Grey/Black hair"
