Dog Crates for Breeders: Size, Cleaning, and Stacking

Build the kennel around cleaning

In a home with more than one dog, crates are part of your hygiene routine. The CDC recommends washing your hands after handling dogs, their food, water dishes, or supplies, and after contact with dog saliva or poop. It also advises picking up dog poop even in your own yard. Choose crates that make those steps easier: smooth surfaces, a removable tray, and enough openings for you to reach every corner.

Clean pet habitats and supplies outside the house when possible, and never clean them in the kitchen sink, food preparation areas, or bathroom sink, according to CDC guidance. Set up a utility sink, hose station, or large tub for crates and trays. Look for removable trays and simple latches if you need to take crates apart for a deep clean. See easy-to-clean dog crates for details on tray removal and materials.

The ASPCA lists a training crate and clean bedding as part of basic dog care, and it recommends washing bedding often. Washable fabric bedding is easier to rotate between dogs than thick beds that trap moisture and hair.

Match the crate to the dog's size and stage

The size rule is the same for every dog, including breeding stock: a crate should let the dog stand, turn around, and lie down in a natural position. Start with the dog crate size chart and learn how to measure your dog for a crate before you buy multiple crates.

A nursing dam needs enough room to stretch out beside her puppies but enough boundary to move away briefly. A wire crate with a divider can be expanded as puppies grow and begin to move away from the dam. For newborn puppies, a dedicated whelping box is safer than a wire crate because it prevents small puppies from slipping through wire gaps. Use regular crates for naps, feeding, and separation, not as a whelping box.

As puppies grow, each one needs its own space for rest and housetraining. Avoid using one large crate for multiple puppies unless you are supervising them. A divider panel is a practical way to adjust the space as the puppy grows. See how to use dog crate divider.

Before a puppy leaves, plan for the trip. The USDA's pet travel page says to contact a USDA-accredited veterinarian as soon as you decide to travel so they can help you meet destination country requirements. For flights, choose a crate that meets the airline's rules for the puppy's size and the cabin or cargo area.

Stack crates safely and keep air moving

Stacking saves floor space, but it only works if the crates are designed for it or if you secure them so they cannot slide. Compare stackable dog crates and stackable vs side-by-side dog crates before deciding.

When you stack, keep the heaviest dog in the bottom crate and put lighter dogs or puppies higher. Avoid placing a crate with a large adult directly above a puppy crate if the upper crate could shift. Check the manufacturer's stacking guidance and use clips, straps, or wall anchors if they are included. If your crates are not stackable, a wire shelving unit can prevent movement, but make sure the dog cannot reach mounting hardware.

Airflow matters more in a stacked row. Keep the sides of each crate clear, avoid placing crates against heat sources, and remove covers on warm days. Read the dog crate ventilation guide for hot and cold weather setup.

Choose materials that stand up to kennel life

For daily cleaning and regular disinfecting, choose surfaces that do not absorb urine or hold odor. Powder-coated wire and molded plastic are easier to wipe down than upholstered furniture or soft fabric. Soft crates are convenient for travel but are not the best primary kennel for breeders because fabric seams are hard to sanitize. See dog crate materials comparison for the tradeoffs.

If you keep adult dogs that are strong chewers or prone to digging, prioritize a sturdy frame and secure latches. A crate frame that flexes makes cleaning and stacking harder. Heavy-duty crates with thick tubes, strong wire, and reinforced doors are built for this kind of environment. Start with the heavy-duty vs standard dog crates guide and then compare options in the best heavy duty dog crates guide.

Watch the tray and door design. A high-sided tray holds more mess, but it also has to be easy to slide out. A tray with a lip that is too low can leak onto the floor. Read dog crate tray depth and material before you choose a tray-style crate for a breeding room.

What to pick for your use

Questions

Can a regular wire crate be used as a whelping box?

No. A regular wire crate is not a safe whelping box for newborn puppies because they can slip through the wire gaps or get caught under the door. Use a dedicated whelping box with solid sides and a low threshold. Once puppies are mobile, a wire crate with a divider can provide a safe napping and feeding space.

How many crates should a breeder have?

Plan for one crate per adult dog plus at least one spare for a new litter, a growing puppy, or a dog that needs to be separated. Having a spare makes cleaning and rotation easier.

Is it safe to stack crates with puppies in the lower levels?

It can be safe if the crates are designed to stack and you secure them so they cannot shift. Place adult dogs on the bottom or on the floor, and avoid placing anything heavy directly above a puppy crate unless the stack is anchored. Check the stack before every use.

What should I do between litters?

Remove all bedding and trays. Wash the crate and tray with hot, soapy water, rinse, and dry completely. Disinfect according to the product label and repeat if needed. Keep cleaning supplies away from the kitchen and food areas, and wash your hands afterward.

Can I cover crates to reduce noise in a kennel?

A cover can help some dogs feel secure, but do not block airflow. Use a cover that leaves vents open and remove it in warm weather. If a dog chews fabric or overheats, skip the cover.
