What is the correct way to measure a dog for a jacket? The correct way to measure a dog for a jacket involves taking three main measurements: the dog’s back length, chest girth, and neck circumference. Getting these three numbers right ensures the coat fits well, keeps your dog warm, and allows for freedom of movement.
Ensuring your dog has a coat that fits properly is vital for their comfort and safety, especially in cold or wet weather. A coat that is too small can restrict movement or cause chafing. A coat that is too big can slip, snag on things, or fail to keep the cold out. This guide gives you the steps for the canine coat measurement guide you need. We will show you the best way to measure dog’s back length and other key areas.

Why Accurate Measurement Matters
Many dog owners skip proper measuring. They guess based on breed or guess based on other items they own. This often leads to poor fit. A good fit means better protection from the elements. It also means your dog is happier wearing the coat.
A proper fit affects:
- Warmth: Gaps let cold air in.
- Mobility: Tight spots stop natural movement.
- Safety: Loose coats can snag on branches or objects.
- Comfort: Rubbing can cause skin irritation or sores.
Tools You Will Need
Before you start, gather your tools. You only need a few simple items.
- Flexible Tape Measure: A cloth or soft plastic tape measure works best. Avoid using a metal ruler, as it cannot curve around the body parts.
- A Helper (Optional but Recommended): Having someone gently hold the dog still can make getting accurate numbers much easier.
- Treats: Keep your dog happy and cooperative during the process.
- Pen and Paper: To record the numbers right away.
Step-by-Step Canine Coat Measurement Guide
There are three key areas to measure. We will look at each one in detail. Remember to measure while your dog is standing squarely on all four paws on a flat surface.
1. Measuring Dog Back Length
This is often the most important measurement for finding the right size in a dog coat length guide. The back length determines how much of your dog’s body the coat will cover from neck to tail base.
The Best Way to Measure Dog’s Back Length
- Start Point: Ask your helper to stand near your dog’s shoulder. Locate the base of the neck where the collar normally sits. This is where the coat should begin. This point is usually right between the shoulder blades.
- The Path: Run the tape measure straight down your dog’s back. Follow the curve of their spine. Keep the tape snug but not tight. Do not let the tape sag.
- End Point: Stop measuring at the very base of the tail. You want the coat to cover the main body area, but usually not the entire tail itself. For short-backed breeds (like Pugs), you might stop slightly sooner. For long-backed breeds (like Dachshunds), ensure you get the full length to prevent lower back exposure.
Tip: Most coats are sized based on this back measurement. Always check the specific dog coat sizing chart for the brand you buy.
2. Determining Dog Girth Measurement for Coat (Chest Measurement)
The girth, or chest measurement, is crucial for ensuring the coat fastens comfortably around the widest part of your dog’s rib cage. This is similar to a dog chest measurement for harness but is used specifically for coats.
How to Get an Accurate Dog Girth Measurement
- Locate the Widest Point: Have your dog stand tall. Find the area just behind the front legs and around the deepest part of the chest. This is usually the widest part of the rib cage.
- Wrap the Tape: Wrap the flexible tape measure all the way around this widest part of the chest.
- Snug Fit: The tape should lie flat against the body. You should be able to slide only one or two fingers comfortably between the tape and your dog’s coat (or skin, if they are short-haired). Do not pull tightly.
This dog girth measurement for coat ensures the coat does not restrict breathing or bend awkwardly when your dog walks or sits.
3. Neck Circumference Measurement
While the neck size is often covered by the back length measurement on many coat styles, some coats have adjustable necks or high collars. It is still good practice to measure this.
How to Measure the Dog’s Neck
- Placement: Measure around the thickest part of your dog’s neck, similar to where a flat collar sits.
- Comfort Level: Allow enough room for comfort. You should be able to fit two fingers easily under the tape measure. This prevents choking or rubbing when the dog moves its head.
4. Weight and Breed Reference (Use with Caution)
While measurements are best, weight can sometimes offer a quick starting point, especially if you are measuring a dog for a sweater where stretch might accommodate small sizing errors. However, weight varies wildly within breeds.
If you are using a dog breed coat size guide, remember that a muscular, deep-chested Labrador might wear the same size as a leaner, leggier one, but their actual measurements may differ greatly. Always prioritize the tape measure results over breed averages.
Interpreting Sizing Charts and Adjustments
Once you have your three primary numbers (Back Length, Girth, Neck), you need to compare them to the specific dog coat sizing chart provided by the manufacturer.
Dealing with Inconsistencies
It is rare for a dog to perfectly match all three numbers on a chart. Here is how to prioritize:
- Back Length: If the back length is too short, the dog’s rear end will get wet or cold. If it is too long, it can interfere with the tail movement or bowel movements.
- Girth: If the girth is too tight, movement is restricted, and breathing can be difficult. If it is too loose, the coat will slide around or fall off.
The Rule of Thumb: For coats, the Back Length is usually the primary sizing factor. Once you select the size based on length, check the chart to ensure the Girth dimension of that size will fit your dog comfortably (remembering the “two-finger rule”).
Table Example: Simplified Dog Coat Sizing Chart Reference
| Size Label | Back Length (Inches) | Girth Range (Inches) | Neck Size (Inches) | Common Breeds (Approx.) |
|---|---|---|---|---|
| Small | 12 – 14 | 16 – 20 | 11 – 13 | French Bulldog, Jack Russell |
| Medium | 16 – 18 | 20 – 26 | 14 – 16 | Beagle, Cocker Spaniel |
| Large | 20 – 24 | 26 – 32 | 17 – 19 | Labrador Retriever, Boxer |
| X-Large | 26 – 30 | 32 – 38 | 20 – 22 | German Shepherd, Great Dane (smaller end) |
Note: This is a generic example. Always use the retailer’s specific chart.
Special Considerations for Different Dog Shapes
Dogs are not built like boxes. Some breeds have body shapes that complicate simple square measurements.
Measuring Short, Stocky Dogs (e.g., Pugs, Bulldogs)
These dogs often have very deep chests but short backs.
- Focus: The dog girth measurement for coat will likely put them in a much larger size category than their back length suggests.
- Action: You must choose the size that fits the girth, even if the back length overlaps slightly. Look for coats designed for “Bully breeds” as they accommodate wider chests. If the coat is too long in the back, look for adjustable closures near the tail to cinch it up slightly.
Measuring Long, Low Dogs (e.g., Dachshunds)
These dogs have very long backs relative to their height.
- Focus: The best way to measure dog’s back length is critical here.
- Action: Select the size based on the length. The girth might be average. Be careful that the front legs have enough opening so the coat doesn’t pull up awkwardly when they walk.
Measuring Deep-Chested Dogs (e.g., Greyhounds, Boxers)
These dogs have chests that dramatically narrow toward the waist.
- Focus: Getting the chest measurement right behind the front legs is key.
- Action: If the chest is snug, the coat will fit well around the deep part, but you must ensure there is enough fabric coverage over the back without binding at the waist. Adjustable straps underneath are very helpful for these shapes.
Measuring a Growing Puppy for a Coat
How to measure a growing puppy for a coat requires looking ahead slightly while prioritizing immediate comfort. Puppies grow fast, so buying a large, expensive coat that fits now but will be too small next month is a waste.
- Measure Current Size: Take all measurements as described above.
- Estimate Growth: Consult with your veterinarian or use online growth charts for the puppy’s breed to estimate their adult size range.
- Buy for the Middle Ground: Purchase a coat that fits well now but has significant adjustability (straps, Velcro, elastic) that will allow it to expand slightly as the puppy grows over the next few weeks.
- Avoid Overbuying: Do not buy an “adult size” hoping it will fit later. An ill-fitting coat on a young puppy can discourage them from wearing outerwear in the future. Focus on getting a comfortable fit for the next 4-6 weeks.
Fathoming Coat Style Differences
Not all coats are measured the same way because they don’t all cover the same area. The dog coat length guide changes based on the style.
Raincoats (Standard Coverage)
These usually cover the back and chest. Measurements 1 (Back Length) and 2 (Girth) are essential. The neck opening is usually simple.
Winter Parkas/Insulated Vests
These often have more bulk and may cover less of the shoulder area to allow arm movement.
- Focus: Ensure the front leg openings are generous. A bulky coat that restricts shoulder movement can cause gait problems.
Harness Coats (Dog Jacket/Harness Combo)
When buying a coat designed to fit over a harness, you must consider where the harness sits versus where the coat closes.
- Action: Measure the dog’s girth where the coat fastens (usually just behind the ribs), not necessarily where the harness straps sit. Many high-quality coats feature a special opening or zipper for leash attachment, which must align with your dog’s D-ring location.
Final Check: The Fit Test
After you bring the new coat home, do a final fit test before heading out into bad weather. This test ensures you have followed the correct way to measure dog for jacket successfully.
- Put it On: Fasten all clips, Velcro, or buckles.
- The Two-Finger Rule Check: Check that you can slide one or two fingers under the chest straps and the neck closure without strain.
- Movement Test: Ask your dog to walk, turn around, sit, and lie down.
- Does the coat ride up over the shoulders when they sit? (Too long or too loose in the back)
- Does it pull tight across the chest when they breathe deeply? (Too small girth)
- Does it rub the armpits or restrict the front leg movement? (Too tight in the armholes)
- Coverage Check: Does the coat cover the major areas needing protection (e.g., the lower back, the front chest)?
If any area fails the test, review your initial measurements against the dog coat sizing chart. Sometimes, moving up or down just one size based on girth alone can solve the issue.
Frequently Asked Questions (FAQ)
Should I add extra room to my measurements?
Generally, no. When measuring, keep the tape snug but comfortable—the “two-finger rule.” Manufacturers build extra allowance into their sizing chart based on the design of the closures (Velcro, snaps, etc.). Adding extra inches yourself often results in a coat that is too loose and ineffective.
How do I stop the coat from irritating my dog’s armpits?
Armpit irritation usually happens because the dog girth measurement for coat was sized correctly, but the coat’s armhole openings are too small or the coat is pulled too far forward. Check that the coat stops at least an inch or two before the front leg joint. If the opening is too restrictive, you might need to choose a different style of coat, perhaps one designed for a deep chest.
My dog is between sizes on the chart. Which size should I choose?
If your dog falls exactly between sizes:
- If the coat is for warmth (winter), choose the larger size. A slightly larger, adjustable coat allows for layering underneath.
- If the coat is for rain or running (lightweight), choose the smaller size. A coat that is too long on a smaller dog flops around and gets in the way of their legs.
Can I use my dog’s harness size to buy a coat?
No. Harnesses are sized differently than coats. A harness size is based on where the straps sit, which is often higher up on the chest and around the rib cage further back. Coat sizing relies on the best way to measure dog’s back length and the girth measurement taken at the deepest part of the chest. Always use the coat-specific chart.
How can I measure my dog if they won’t stand still?
Use high-value treats. Have one person gently hold the dog’s head up or distract them with food while the other person quickly takes the measurement. For the back length, you might need to quickly measure the distance while the dog is lying down, then stand them up and check that measurement quickly against the lying measurement, as lying down can sometimes slightly shorten the perceived back length. Speed and a calm demeanor are essential when measuring a dog for a sweater or coat.
