How to Choose the Right Guard Dog in the U.S.

Before selecting a protection breed, consider the following:

✔ State Regulations

Some U.S. states or insurance providers may have restrictions or special requirements for certain breeds.

✔ Living Space

Large working breeds require room to move and structured activity.

✔ Training Commitment

A guard dog without training is not protection. It is liability.

Protection does not mean aggression. Early socialization is critical.
