Dog Cave Beds for Small Dogs: Choosing the Right Size

If you live with small dogs—especially a pair of tiny rowdy ones—you already know they don’t just sleep in their beds. They use them as wrestling rings, hideout spots for stolen socks, and safe zones when the vacuum cleaner comes out. So when it comes to picking a Dog Cave Bed, the biggest dilemma isn’t color or fabric. It’s size.

Get it too small, and they’re squeezed like sardines. Get it too big, and you worry they’ll lose that snug, enclosed "cave" feeling that calms their nerves.

If you’re stuck between sizes, here’s a breakdown based on real pet-parent tests and why going one size bigger is usually the best decision you'll make.

The Size Dilemma: What Does Your Pup Actually Need?

Most standard dog bed size charts tell you to measure your dog from nose to tail while they’re asleep. But cave beds don't work like that! Because of the hooded top, sleeping style and dog personality matter way more than weight alone.

Here is the quick breakdown we use at Dogegis™:

• Small / 20-Inch: Ideal for single, super-tiny pups (under 5 lbs) like a solo Chihuahua or Yorkie who strictly sleeps in a tight little donut.
• Medium-Large / 24-Inch: The absolute sweet spot if you have a 5–8 lb dog that likes to sprawl, or if you have two small dogs sharing one nest.

A Quick Reality Check from a Dog Parent:

If your dogs are the type to run, roll around, and drag toys into their bed, skip the small size. They need headroom to turn around without knocking the hood down!

Why the 24-Inch Bed is Magic for Two Small Dogs

A lot of dog owners hesitate to get a 24-inch bed for 5-8 lb dogs because they think, "Is this going to look ridiculously huge in my living room?" or "Will my dogs still feel safe?"

Here’s what one Dogegis™ customer shared after trying the 24-inch model for her two little pups:

"I have two small 5-8 lb dogs. So far one hasn’t left the bed. I bought the 24 inch. It has more room than they need but the way they run and play, the extra room will be fine. The top has a wire to keep the opening open as long as the dogs don’t chew into it. Anyhow. I like it. They like it 😇"

That "extra room" isn't wasted space. Here’s why it works so well in real life:

• Wrestle-Friendly Clearance: Small dogs don't just collapse into bed; they do three aggressive zoomies, pounce on each other, and dig before settling down. The 24-inch gives them room to be silly together.
• Double-Cuddle Thermal Comfort: Two 5-8 lb dogs in a 24-inch cave have just enough space to sleep back-to-back without overheating, while still trapping their combined body heat inside the hood.
• The "Velcro Dog" Fix: Pups that get separation anxiety when you leave the room often calm down instantly because the generous depth feels like a warm hug from behind.

The Dogegis™ Difference: 3 Details That Keep Pups Coming Back

Not all cave beds hold up in a real house with real dogs. We built our Dogegis™ CozyNook™ Cave Bed specifically to fix the annoying flaws found in cheap online knockoffs.

1. Built-In Stay-Open Hood Wire (No Collapsing On Their Heads)

There is nothing sadder than a cave bed that flops flat the second your dog tries to step inside. Our top rim features a custom flexible support wire sewn securely into an inner fabric channel. It holds the entrance wide open so your dog can see the cozy interior and hop in without hesitation.(Just a quick tip for chewers: As long as your pups aren't actively trying to eat through the reinforced inner lining to get to the frame, this wire will keep its shape for years!)

2. High-Density Orthopedic Base (Soothes Joints & Pain)

Small dogs have fragile joints—especially breeds prone to arthritis, IVDD, or knee issues. Instead of cheap poly-fill that flattens out after two weeks, Dogegis™ uses high-resilience filling that cushions joints and keeps cold floor drafts away from your pup's belly.

3. Machine Washable & Easy-Zip Maintenance

Let's be honest: dogs bring drool, backyard dirt, and half-chewed bully sticks into their favorite spots. The entire outer cover zips off smoothly so you can throw it in the washing machine without wrestling with the padding inside.

Final Verdict: Which Size Should You Add to Cart?

If you have a single tiny pup under 5 lbs who only sleeps tightly curled, the 20-inch will do the trick. But if you have two small dogs (5–8 lbs each), an active pup who loves to stretch, or a dog that treats their bed like a play fort, go straight for the 24-inch Dogegis™ Cave Bed. As our reviewer put it so perfectly: "I like it. They like it 😇"
