Stackable Dog Crates: What to Check Before Buying

Why stacking changes the checklist

Stacking dog crates can save floor space when you need to keep multiple dogs in one room. A crate designed to sit alone on the floor is not automatically safe to support another crate. When you add a second crate, you change the load on the frame, the way you reach the doors, and the airflow around the dogs inside.

The buying question is not simply whether a crate can stack. It is whether the frame can hold the upper crate without bending, whether every door stays secure, whether waste stays contained, and whether the dogs in both crates stay comfortable. Start with the maker's own specification page and confirm the word "stackable." If that information is missing, treat the crate as a single-level crate. For a side-by-side alternative, see stackable vs. side-by-side dog crates.

Confirm the maker says it is stackable

Some wire crates are built with a flat, reinforced top and a frame designed to carry the weight of another crate. Others have a top that is only meant to hold a cover or a light item. The manufacturer's specification page is the right place to look. If the maker does not say the crate is stackable, do not assume it is. Stacking an unsupported crate can bend the frame, pop a door loose, or cause the upper crate to slide.

When you compare models, pay attention to the frame material and how the corners meet. Crate materials comparison explains how steel, plastic, and fabric behave under load. A soft-sided crate usually cannot support another occupied crate unless the maker specifically designs it with a rigid frame and a reinforced top. If you need to know how much weight a given frame can hold, read the weight capacity guide and check the maker's published specs.

Check the frame, corners, and top

A stackable crate needs a rigid frame and a top that will not flex. Wire crates with continuous vertical bars or reinforced corners tend to be stronger than crates with thin panels that rely on the top rim for strength. Look for a top that sits flat against the bottom tray of the crate above it. If the top surface has a lip, handle, or feeder door that stops the upper crate from sitting square, the stack can shift.

A low center of gravity is safer. Put the heavier or more active dog in the lower crate because the lower position is closer to the floor and more stable. Use the heavy duty dog crates guide when you need a frame built for large, strong dogs.

• Flat or minimally recessed top so the upper crate has full contact.
• Reinforced corners or stacking brackets supplied by the maker.
• A frame made of steel tube or heavy wire rather than thin plastic.
• Clear instructions on which crate should go on the bottom.

Look at door latches and escape points

When crates are stacked, the doors are still your main access points. Check every latch from the angle you will use it. A top crate's door may be at shoulder height or higher, so the latch should open smoothly. On the lower crate, a door may be harder to reach if the upper crate sits close to it. Consider double door dog crates if you need access from both sides in a tight stack.

An anxious dog may push hard against a door, and stacking can change how the frame absorbs that force. The ASPCA notes that dogs with separation anxiety may try to escape through doors and windows, and those attempts can cause injury. That is why the latch, hinge, and door frame on every crate in the stack need to be secure. The dog crate safety checklist covers the escape points to inspect before relying on the setup.

Check trays, cleaning, and waste containment

The tray is part of the stack because it sits between one dog and the dog below. A tray that slides out from the side is easier to remove when the crate is stacked, but only if the upper crate is positioned to leave room. A fixed tray may be simpler if you do not plan to move the stack often. Check the tray lip height and how far the tray extends under the door. Dog crate tray depth and material explains what to look for.

When multiple crates are in one room, cleaning and hygiene matter. The CDC advises washing hands after handling pet habitats and equipment and picking up dog waste promptly. A tray with a tight fit and a raised lip makes that routine easier. If you are setting up crates in a bedroom or carpeted area, the apartment dog crate guide has more layout advice.

Think about airflow and temperature

Both dogs need air even when one crate is directly above the other. Wire and mesh crates allow airflow on all sides, which makes them easier to stack safely. Plastic kennels often have ventilation only in certain panels, so check whether the model has vents on the top or sides that line up with the gap between crates. A solid-top crate may trap heat for the dog underneath. The dog crate ventilation guide explains how to judge openings.

Do not stack crates in a warm spot just because the footprint is small. The ASPCA's general dog care guidance says a dog needs a warm, quiet place to rest and access to shade and cool water in hot weather. A stack should not block the lower dog from airflow or make either compartment noticeably hotter.

Anchor the stack and supervise children

A stack is still a piece of furniture. It can tip if a dog jumps, shifts, or scratches at the door. If the manufacturer provides wall anchors or stacking brackets, use them. If not, place the stack against a wall and keep the upper crate as empty as possible when the lower crate is occupied. Avoid lifting a heavy occupied crate onto another occupied crate.

Children should not climb on or play around a stack of dog crates. The CDC advises supervising young children around dogs and teaching them to handle pets with care. A child pulling on a top crate door could pull the entire stack down. The dog crate safety checklist and the multiple dog crates in one home guide can help you plan a safe layout.

What to pick for your use

Questions

Can I stack crates that were not sold as stackable?

No. If the manufacturer does not say the crate is stackable, assume the frame and top are not designed to carry another crate. Stacking an unapproved crate can bend the frame or cause the upper crate to fall. Consider stackable vs. side-by-side dog crates when you need multiple crates.

Which crate should go on the bottom?

Put the heavier or more active dog in the bottom crate. The lower position is closer to the floor and more stable. If one dog is likely to push against the door, that dog should also be on the bottom so the whole stack is less likely to shift.

Are soft crates stackable?

Most soft crates are not designed to support another crate. Only use a soft crate as part of a stack if the maker states it is stackable and gives assembly instructions. Otherwise choose a wire or heavy duty crate for stacking.

How do I keep a stacked setup from tipping?

Use maker-supplied brackets or wall anchors, place the stack against a wall, and keep the heavier dog in the bottom crate. Make sure every door is latched and children cannot climb on the crates.

Do I need to worry about temperature in a stack?

Yes. The top crate can be warmer and the bottom crate can get less airflow. Use crates with open mesh or wire sides, keep the stack out of direct sun, and check both dogs for signs of overheating.
