Choosing the Right XL Crate for Your Dog
Prioritize Crash Certification for Road Use
If your dog travels in cars regularly, CPS-certified crates (GUNNER, Lucky) are essential for true protection.
Balance Weight and Portability
Hard-shell crates are heavy—ideal for permanent installs. The Impact HD provides a compromise with collapsibility.
Match Size to Dog’s Comfort
Extra-large crates support large breeds’ ability to stand, turn, and lie comfortably—ensuring calm crate behavior :contentReference[oaicite:4]{index=4}.
Consider Your Dog’s Behavior
Destructive chewers or escape-artist dogs need rotomolded security and solid latches—avoid soft crates entirely.
Ensure Proper Vehicle Fit and Installation
Measure your cargo area and secure crate with high-strength anchor straps—not seatbelt loops—for crash integrity.
