1. French Bulldog
The French Bulldog might not look like a typical guard dog with its cute, wrinkly face and bat-like ears, but don’t let that fool you. This little dog, weighing between 16 and 28 pounds, comes from France and has a big personality. Frenchies are super loyal to their owners and always keep an eye on what’s going on around them. They’re not loud barkers, but they’ll let you know with a sharp yap if someone strange is at your door.
Because they’re small, they don’t need a big space—just a cozy corner of your apartment works fine. They’re not super active either, so a short walk or some playtime inside keeps them happy. Their short fur means you don’t have to brush them much, and they love snuggling up with you after a day of guarding. If you want a tiny but brave friend for your apartment, the French Bulldog is a great choice.
