Choosing the Right Heavy‑Duty Crate
1. Prioritize Crash Certification for Road Use
If you travel by vehicle frequently, choose CPS-certified crates like GUNNER or Lucky. Standard plastic or soft crates won’t provide crash safety :contentReference[oaicite:12]{index=12}.
2. Match Weight vs Portability Needs
Hard-shell units are heavy—they’re secure but need effort to move. Collapsible crates like Impact offer a compromise for frequent pack-up needs.
3. Consider Dog Size and Strength
Large, strong dogs (60 lb+) should use hard-shell or heavy-duty rotomolded crates. Avoid collapsible soft crates that they might break out of.
4. Vehicle Fit & Installation
Ensure proper fit in your vehicle and use strength-rated tie-downs—not seatbelt loops—to secure the kennel safely :contentReference[oaicite:13]{index=13}.
5. Training & Acclimation
Introduce the crate gradually at home. Use it during shorter drives with familiar bedding and treats to build calm associations before long trips.
