Quick answer
Measure your dog from nose to tail base and add 6–10 inches of room, then match that number to the bed's outer dimensions. If your dog curls tightly, a round donut-style bed in the smaller end of the range works; if they sprawl or stretch out, size up. When in doubt, choose the larger size for orthopedic support.
A dog bed that's too small forces your large dog to sleep curled or hanging off the edge, which defeats the purpose of an orthopedic bed. Too large, and the bolsters stop providing the head and neck support that helps joints rest.
The right Bully Bed size comes down to three things: your dog's measured length, how they actually sleep, and the floor space you can give up. This guide walks through each decision so you can order once and get it right.
Measure your dog, not the old bed
Start with a soft tape measure. With your dog standing, measure from the tip of the nose to the base of the tail, then measure the widest point across the shoulders. Write both numbers down. If your dog is between sizes or still growing, use the larger measurement as your baseline.
Next, measure where the bed will live. Leave at least a few inches of clearance on all sides so your dog can step on and off without squeezing past furniture. A bed that blocks a doorway or crowds a walkway usually gets avoided, no matter how comfortable it is.
- Measure nose to tail base while standing, not curled up.
- Add 6–10 inches to that length for sleeping room.
- Check floor clearance before you commit to a size.
Match the shape to how your dog sleeps
Curled sleepers tuck their nose toward their tail and use bolsters as a headrest. A round donut-style bed suits them because the raised edges create a sense of security and the center stays supportive. The Faux Fur Orthopedic Dog Bed is built this way, with soft bolsters and a deep donut shape that gives dogs a calming place to settle.

Sprawlers and side-sleepers stretch out flat. They need a longer sleeping surface, so a rectangular or standard Bully Bed shape usually fits better. If your dog changes positions through the night, prioritize length over width.
- Curler: round donut bed with bolsters.
- Sprawler: longer rectangular surface.
- Position-changer: size up for length.
Sizing for joint support, not just comfort
An orthopedic bed only helps if your dog's weight is fully supported. If their hips or elbows hang over the edge, the foam can't do its job. That's why the general rule for orthopedic dog bed size is to size up rather than down, especially for seniors or dogs recovering from strain.
Bully Bites Joint Supplements for Dogs are formulated with a blend that includes Rimoxen, a naturally derived anti-inflammatory, and a Cox-2 inhibitor to help reduce inflammation and pain. Supplements support joint health from the inside; the right bed size supports it from the outside. Both matter for large breeds.
Bully Bites Joint Supplements for Dogs
- No overhang at hips or elbows.
- Seniors and post-injury dogs benefit most from extra room.
- Pair a correctly sized bed with joint support for best results.
Covers and replacements: get the size right the first time
If you already own a Bully Bed and need a fresh cover, match the cover to the bed you have, not to your dog's measurements. Original Orthopedic Bully Bed Covers fit the original Bully Bed and come in tan, gray, or chocolate. They're removable, washable, and zip on and off easily.
If you have a chew-resistant bed, the Chew Proof Dog Bed Replacement Cover is the correct fit. These do not fit the original beds, and they don't carry the damage replacement warranty that the chew-resistant beds do. Checking which bed you own before ordering a cover saves a return.
- Original bed → Original Orthopedic Bully Bed Covers.
- Chew-resistant bed → Chew Proof Dog Bed Replacement Cover.
- Covers are not complete beds.
Decision rules for choosing your Bully Bed size
- If your dog curls into a ball: Choose a round donut-style bed and match the inner sleep area to your dog's curled length plus a few inches. The bolsters do the rest of the support work. Faux Fur Orthopedic Dog Bed is built for this sleeping style.
- If your dog stretches out flat: Prioritize length. Measure nose to tail base and add 6–10 inches, then pick the rectangular size that meets or exceeds that number. Never size down for a sprawler.
- If your dog is a senior or has joint issues: Size up so hips and elbows stay fully on the foam. Pair with a joint supplement like Bully Bites for inside-out support. Overhang undermines orthopedic benefits.
- If you're only replacing a cover: Match the cover to your bed model, not your dog. Original beds take Original Orthopedic Bully Bed Covers; chew-resistant beds take the Chew Proof Dog Bed Replacement Cover. Covers are not interchangeable between models.
Product facts that affect sizing
- Faux Fur Orthopedic Dog Bed: Deep donut style with soft, supportive bolsters and foam; faux fur stays cool. Best for curled sleepers who want a calming, secure shape. The bolster height means you don't need to oversize as much for head support.
- Original Orthopedic Bully Bed Covers: Fits the original Bully Bed; washable, removable microfiber; available in tan, gray, or chocolate. Order the cover in the same size as your existing Bully Bed. A cover sized for a different bed won't zip correctly.
- Chew Proof Dog Bed Replacement Cover: Fits chew-resistant beds only; does not fit original beds and does not carry the chew-resistant damage replacement warranty. If your dog is a chewer, confirm which bed model you own before buying a cover, or you'll get the wrong fit.
- Bully Bites Joint Supplements for Dogs: Soft chews formulated with Rimoxen, a naturally derived anti-inflammatory, and a Cox-2 inhibitor to help reduce inflammation and pain. Joint support works alongside a properly sized orthopedic bed. Sizing up gives the supplement a better chance to help because weight is evenly supported.
Who this sizing approach fits
Best for
- Large and bully breed dogs who need full-body joint support
- Owners replacing a cover and wanting to confirm the right size
- Senior dogs or dogs recovering from strain who need extra room
Not for
- Owners looking for a bed that doubles as a crate mat with exact crate dimensions
- Dogs who chew through beds and need the chew-resistant model rather than a standard size
- Homes with very tight floor space where a larger bed won't fit safely
Measure your dog, match the shape to their sleeping style, and size up when in doubt. That combination gets you a Bully Bed that supports joints properly and lasts. If you're only replacing a cover, confirm your bed model first so the fit is right.
