Measure your dog and use the chart for the exact EzyDog harness you are buying. Chest Plate Medium and Quick Fit Medium cover different girth ranges, so a remembered letter size is not enough. Check neck, girth and the listed weight range together; if they point to different rows, ask EzyDog before choosing.
A 50 cm chest measurement can appear in several Chest Plate rows and only one Quick Fit row. That narrows the comparison, but it does not establish that every other measurement fits. Keep the exact model name with the measurements when comparing products online.
Where do you measure a dog for a harness?
Start with the neck and girth measurements, then check them against the chart’s weight range. EzyDog defines girth as the circumference of the torso directly behind the front legs. Neck is the circumference of the neck where a collar would sit. Both charts are metric, in centimetres and kilograms.
EzyDog publishes a third measurement, length, taken from the base of the neck to the base of the tail. Neither harness chart has a length column. Use the columns published for the product; do not add a length requirement to either chart.
Take both measurements with the dog standing, using a soft tape. Write them down. You will need them again on the next product page. Both charts below show neck, girth and weight; keep each value with the row it belongs to.
What size EzyDog Chest Plate harness does my dog need?
These are EzyDog Australia’s own figures for the Essential Chest Plate Harness, read from its product page in October 2026.
Find the rows containing your girth measurement, then check neck and weight in each of those rows. Several girth ranges overlap. Being inside one column is a reason to examine a row, not proof that the whole size suits the dog.
| Size | Weight (kg) | Neck (cm) | Girth (cm) |
|---|---|---|---|
| XXS | 1–3 | 23–37 | 24–38 |
| XS | 3–5 | 27–46 | 29–48 |
| S | 5–10 | 34–56 | 37–60 |
| M | 10–19 | 41–68 | 45–73 |
| L | 19–35 | 46–78 | 49–84 |
| XL | 35+ | 52–90 | 56–97 |
The chart above stops at XL for a reason. EzyDog’s Essential page and its corduroy version of the Chest Plate publish different girth ranges for the XXL. For a dog that big, read the chart on the page for the exact product and variant you are buying. If the figures on the two pages do not agree, ask EzyDog’s customer service team.
The Chest Plate Medium product details are on the online shop. That is a model example, rather than a recommendation that every reader needs Medium or confirmation of current stock.
What size EzyDog Quick Fit harness does my dog need?
The Quick Fit Harness carries its own chart. These are EzyDog Australia’s figures for that model, read from its own product page in October 2026.
Put the two girth columns beside each other and the difference shows. Each Quick Fit girth range is narrower, but neither its lower nor upper limit can be copied from the Chest Plate chart. Its small covers 46 to 55 cm, while the Chest Plate small covers 37 to 60 cm. Weight bands match from XS up. The smallest size is the exception. Chest Plate XXS starts at 1 kg, and Quick Fit XXS starts at 2 kg.
| Size | Weight (kg) | Neck (cm) | Girth (cm) |
|---|---|---|---|
| XXS | 2–3 | 23–38 | 30–38 |
| XS | 3–5 | 28–46 | 38–46 |
| S | 5–10 | 36–56 | 46–55 |
| M | 10–19 | 41–69 | 55–67 |
| L | 19–35 | 45–79 | 67–84 |
| XL | 35+ | 53–91 | 84–107 |
Why is the same letter a different size?
Take a dog measuring 50 cm around the girth. In the EzyDog Chest Plate harness chart, 50 cm sits inside small, medium and large. In the Quick Fit chart it sits inside small only, because Quick Fit medium starts at 55 cm. Those are girth matches, not three approved Chest Plate sizes or a final Quick Fit Small recommendation.
Weight makes it harder again. A 12 kg dog falls in the 10 to 19 kg band, which both charts label medium. If that dog measures 50 cm around the chest, the Quick Fit medium girth range does not reach them. The girth falls in Small, while the weight falls in Medium. Neither row matches both values, and the neck measurement is still needed.
Do not resolve that mismatch by ignoring the weight column or choosing the smallest row that includes the girth. EzyDog directs uncertain buyers to its customer service team. Give them the model name and all the measurements so they can address the mismatch.
Before comparing a row, check three things:
- It belongs to the exact product and variant you intend to buy.
- The neck and girth figures are in centimetres, with weight in kilograms.
- You have checked the whole row, rather than matching one number and stopping.
A letter belongs to a particular model chart. It does not carry a fixed set of measurements across the EzyDog range.
What if my dog is between sizes?
EzyDog publishes no rounding rule on either product page. It tells buyers who are between sizes, or not sure, to get in touch with its own customer service team. That is the manufacturer’s own answer.
Do not borrow a size-up rule from a coat or a different harness. A larger row changes more than one limit, so it is not a substitute for checking the whole chart. If you cannot find a row that matches, follow the manufacturer’s support direction rather than rounding a measurement to make it fit.
Check the exact product and variant as well as the model. The corduroy Chest Plate and the Essential Chest Plate share a name and publish different figures at the top of the range.
For a growing dog, recheck current measurements and the fit rather than choosing for an expected future size. The current chart cannot establish how fast an individual puppy will grow. Recheck as the dog grows rather than relying on the measurements from the last purchase.
How do you check the harness once it is on?
Fit it with the dog standing, then watch the first few minutes of walking. Follow the adjustment instructions for that exact model, because straps and buckles differ between them. A harness that looks right on a still dog can show a rubbing point once the dog moves.
For the broader choice of a collar or harness for walking, use the separate walking guide. Keep the model chart and its adjustment instructions beside you while checking the harness.
If your dog coughs, limps, seems sore, or refuses walks once the harness is on, speak with a vet. Sizing is retail information, not a health check.
Frequently asked questions
Can I buy the same letter size as my dog’s last harness?
Do not assume it transfers. The same letter can cover different dimensions in another model. Compare current measurements with the exact product chart before settling on the size.
Should I go by my dog’s weight or their measurements?
Read all three columns together. A neck or girth match does not explain away a conflicting weight range. Take the mismatch to EzyDog rather than treating one column as permission to ignore another.
How do I measure a dog with a thick coat?
Use EzyDog’s defined neck and girth positions. If the coat leaves you unsure how to take a useful measurement, ask its customer service team for guidance. Do not guess a subtraction from the number you read.
My puppy is still growing. Which size do I buy?
Choose for the puppy’s current measurements and check the fit as they grow. A future size is not evidence of a suitable fit today. Ask EzyDog if the current values do not line up in one row.
Compare EzyDog harness sizes before buying
Write the girth and the neck down in centimetres before you shop, and keep them on your phone. With both numbers in hand you can compare the walking range. Then settle the size on each product page rather than guessing from a letter.
If you are nearby, bring the dog into Belvedere’s Pet Supplies at 93 Upper Heidelberg Road, Ivanhoe, if that is practical. Fit is easier to judge with the dog standing in the harness. Use the exact product chart to narrow the choice, then check the fit on the dog. A chart match alone is not a fit guarantee.
