Safety Information
- Always remove your dog's collar before placing them in the crate to prevent choking hazards.
- When introducing your dog to the crate, allow them to explore it at their own pace. Initially, do not lock the door.
- Place chew toys inside the crate to create a positive association and reduce anxiety.
- Ensure the crate is placed on a stable, level surface.
- Regularly inspect the crate for any damage or loose parts that could compromise safety.
- The non-toxic hammer-tone coating is safe for pets, even if licked or bitten.
Choosing the Right Crate Size: To ensure your dog's comfort, measure your dog's length and height. Add at least 4 inches to both measurements to allow for comfortable movement and standing within the crate.

Operating Instructions
Using the Double Doors
The crate features wide-opening double doors with low thresholds for easy access. To open, slide the bolt latches and pull the doors outwards. This design allows for convenient interaction with your dog and easy feeding.
Locking Mechanism
The double sturdy slide bolt latches provide ultimate security, making the crate chew-proof and escape-proof. Ensure both latches are fully engaged when the door is closed to prevent accidental openings.
Mobility and Stability
The 360-degree swivel caster wheels allow for easy movement of the crate. To secure the crate in place, engage the brakes on the wheels. This prevents unintended rolling and ensures stability.

Maintenance and Cleaning
Regular cleaning and maintenance will extend the life of your BOLDBONE dog crate and ensure a hygienic environment for your pet.
- Tray Cleaning: The removable wire trays and leak-proof plastic pans can be easily slid out from the bottom of the crate. Clean them with mild soap and water, then rinse thoroughly and dry before returning them to the crate.
- Crate Frame Cleaning: Wipe down the steel frame with a damp cloth and mild, pet-safe cleaner. Avoid abrasive cleaners that could damage the hammer-tone coating.
- Inspection: Periodically check all bolts, latches, and wheels to ensure they are secure and functioning correctly. Tighten any loose hardware.
- Storage: For long-term storage, the crate can be disassembled in seconds thanks to its patented construction, making it compact and easy to store.

Troubleshooting
- Dog Anxiety in Crate: If your dog shows anxiety, ensure the crate is a positive space. Place familiar bedding, toys, and treats inside. Gradually increase the time spent in the crate, starting with short periods and leaving the door open. Never use the crate as punishment.
- Difficulty Moving Crate: Check that the caster wheels are unlocked. If wheels are stiff, clean any debris from the wheel mechanisms.
- Crate Doors Not Securing: Inspect the slide bolt latches for any obstructions or misalignment. Ensure the doors are fully closed before attempting to engage the latches.
- Unstable Crate: Verify that all assembly hardware is tightened. Ensure the crate is on a flat, even surface.
