How to Measure Your Dog for the Perfect Clothing Fit

One of the biggest challenges of buying dog clothes online is getting the right size. A jacket that's too tight can restrict movement and cause discomfort, while one that's too loose won't keep your dog warm. The good news? Measuring your dog correctly is simple — and it makes all the difference.

What You'll Need

• A soft measuring tape (or a piece of string and a ruler)
• Treats to keep your dog still!
• A helper if your dog is wriggly

The 3 Key Measurements

1. Back Length

Measure from the base of your dog's neck (where the collar sits) to the base of the tail. This is the most important measurement for jackets, sweaters, and coats.

2. Chest Girth

Measure around the widest part of your dog's chest, just behind the front legs. Make sure the tape is snug but not tight — you should be able to slip two fingers underneath.

3. Neck Girth

Measure around the base of the neck where the collar sits. This is especially important for turtleneck sweaters and hoodies.

Tips for Accurate Measurements

• Always measure your dog standing up, not sitting or lying down
• Take measurements twice to make sure they're consistent
• If your dog is between sizes, size up for comfort
• Compare your measurements to the specific size chart for each product — sizing can vary between styles

Understanding Size Charts

Most dog clothing uses a combination of back length and chest girth to determine the right size. At PupStyle Boutique, every product includes a detailed size chart — always check it before ordering.

When in Doubt, Size Up

If your dog is between sizes, we always recommend going up a size. A slightly larger fit is more comfortable and easier to put on, and most of our designs have adjustable closures for a more customised fit.
