How to Pick the Right Sized Crate for a Fast-Growing Puppy

Updated 2026-07-22 · 1 Tier Finds

Buying a crate for a puppy is a gamble because you're shopping for a dog that doesn't exist yet. If you buy for their current size, you'll be replacing it in three months. If you buy for their adult size, they might treat the excess space as a bathroom. Learning how to size puppy crate options correctly requires a balance between current comfort and future growth.

The Golden Rule of Crate Sizing

A dog should be able to stand up without hitting their head, turn around in a full circle, and lie down comfortably on their side. If the crate is too small, it’s a cage; if it’s too large, it’s a room. Puppies are opportunistic—if they have a corner far enough away from their sleeping area, they will use it as a toilet, which ruins your potty training progress.

The most practical solution is a divider panel. When researching how to size puppy crates, look for models that include a metal dividing wall. This allows you to start with a small footprint and slide the wall back as the puppy grows, maintaining the "den" feel without buying three different crates over two years.

Choosing Your Material: Budget vs. Premium

Not all crates are built the same, and your choice depends entirely on your dog's chewing habits and your home's aesthetic. I categorize these into three price and durability tiers:

• Budget ($40 - $90): Standard wire crates. These are the gold standard for training because they provide great ventilation and visibility. They are lightweight and easy to move, but they aren't the most attractive and can be noisy.
• Mid-Range ($100 - $250): Heavy-duty plastic or reinforced wire. Plastic crates (kennels) are better for travel and anxious dogs who prefer a more enclosed feel, though they can be harder to clean if a puppy has an accident.
• Premium ($300 - $800+): Furniture-style wooden crates or high-gauge steel. These double as end tables or desks. While they look great, ensure they have a removable metal tray and a secure lock; some "furniture" crates prioritize looks over actual security for chewers.

Avoiding Common Sizing Mistakes

One of the biggest errors I see is owners buying a crate based on the puppy's current weight rather than the breed's projected adult weight. Always shop for the adult size but use a divider to scale it down. If you are adopting a mixed breed, ask the shelter for the projected size or err on the side of a slightly larger crate with a flexible divider.

Another mistake is ignoring the "turn around" test. Some budget crates have awkward dimensions that are long but narrow. If your dog is a breed known for a deep chest (like a Great Dane or Mastiff), prioritize height and width over length. When browsing Dog Supplies on Amazon, check the actual dimensions in the product description rather than relying on the "Small/Medium/Large" labels, which vary wildly by brand.

Gear for Chewers and High-Energy Breeds

If you have a Lab, Shepherd, or any "land shark" puppy, a standard wire crate might not be enough. Some puppies will chew through the wire or bend the bars. For these dogs, look for "heavy-duty" or "industrial" crates made of steel with powder-coated finishes.

To make the crate a positive space, pair it with the right accessories. Avoid thin, fluffy beds that can be shredded and swallowed; instead, opt for durable, chew-resistant mats or washable crate pads. Adding a heavy-duty chew toy inside the crate helps the puppy associate the space with relaxation and mental stimulation rather than confinement.

Setup and Maintenance Tips

Where you put the crate is as important as the size. Place it in a low-traffic corner of a room where the dog can see you but isn't in the middle of the action. This reduces anxiety and prevents the dog from feeling isolated.

Maintenance is simple but necessary. For wire crates, use a handheld vacuum for the bedding and a mild soap solution for the bottom tray. If you have a plastic kennel, a quick spray-down with a pet-safe enzymatic cleaner is the best way to remove odors that might tempt a puppy to mark their territory. Check the locks and hinges monthly; puppy teeth can loosen screws or bend latches over time.

FAQ

What do I do if my crate doesn't have a divider?

You can create a makeshift divider using a piece of sturdy cardboard or a plastic bin. However, for safety and durability, it is better to invest in a crate specifically designed with a sliding divider to ensure the puppy can't push through or chew the barrier.

Should I put a bed in the crate immediately?

Wait until your puppy is reliably potty trained. Puppies often chew beds when they are nervous or bored, and absorbing urine into a bed makes the crate smell, which encourages more accidents. Start with a washable liner or a bare tray.

How do I know when to move the divider back?

Move the divider when your puppy starts looking cramped—specifically, if they can no longer turn around comfortably or if they are bumping into the wall when they shift positions during sleep. Usually, this happens every 2-4 months during the primary growth phase.
