How to Sew a Custom Dog Raglan Sweatshirt

A little sweatshirt, made for a little adventurer!

This project features a handmade raglan-sleeve sweatshirt for a 3.5-month-old male Miniature Schnauzer. The real sewing process was documented by a Pongrabbit user, from preparing the printable pattern and cutting the fabric to sewing and trying on the finished outfit.

The sweatshirt was made with sage-green wool-blend air-layer fabric, matching neck and sleeve cuffs, and a small embroidered “Adventure Awaits” patch.

The finished shape looks structured and adorable, but the maker also discovered a few important things about fabric stretch and fit. The neckline and cuffs were snug, and the overall garment felt slightly small. Nevertheless, the owner reported that the puppy could move, play, and go to the bathroom normally without showing signs of discomfort.

In this project, we'll share the real making process, the puppy's measurements, the finished garment, and what the maker plans to improve next time.

The printable pattern was generated using Pongrabbit, our digital dog clothing pattern-making tool.

About the Pattern

The sewing pattern was prepared using Pongrabbit, a digital tool that generates dog clothing patterns based on measurements.

Note: This project uses a real customer's sewing experience. The maker found that the main fabric had limited stretch and plans to use softer, stretchier fabric and rib-knit cuffs in her next version.

Before preparing the pattern, the owner measured her 3.5-month-old male Miniature Schnauzer.

Here are his actual measurements:

1. Neck circumference: 20.5 cm
2. Back length: 21 cm
3. Chest width: 5 cm
4. Chest circumference: 31.5 cm
5. Head circumference: 23 cm
6. Distance between ears: 7 cm
7. Front leg circumference: 10 cm
8. Front leg length: 12 cm
9. Hind leg circumference: 13 cm
10. Hind leg length: 13 cm

These measurements describe this particular puppy, not a standard clothing size.

Accurate measurements provide a useful starting point for generating a custom sewing pattern. However, the final fit also depends on the fabric, seam allowances, sewing techniques, and the amount of ease in the garment.

Since puppies grow quickly, always measure your dog again before starting a new sewing project.

The maker prepared a printable raglan-sleeve sweatshirt pattern using Pongrabbit.

After printing, the paper pattern pieces were arranged and checked before cutting the fabric.

The photos show the separate body, sleeve, and finishing pieces, along with fold lines and other construction markings.

Before cutting, it's important to:

1. Check the printing scale.
2. Assemble the printed sheets according to the pattern instructions.
3. Identify the front, back, sleeve, and finishing pieces.
4. Check the fold markings and cutting directions.
5. Confirm whether seam allowances are included.

Maker's feedback: The owner suggested arranging the pattern pieces more compactly on the printed sheets, which could make assembling the paper pattern easier.

This is useful feedback for improving the printing and assembly experience of digital sewing patterns.

The photos show the Chinese-language pattern used by the original maker. Pongrabbit also offers an English-language interface, so international makers can use the pattern generator without navigating the Chinese interface.

For this sweatshirt, the maker selected a sage-green wool-blend air-layer fabric.

The printed paper pieces were placed on the fabric, and the cutting process was recorded on video.

After cutting, the individual fabric pieces were laid out on the worktable.

When cutting fabric for a dog sweatshirt, pay attention to the grain direction, fabric stretch, fold markings, and seam allowances.

The maker later noticed that this particular fabric did not stretch very much, which may have contributed to the snug fit of the finished sweatshirt.

For a future version, she plans to try a softer and more elastic fabric.

Tip: Before cutting your final fabric, test how much it stretches and whether it recovers its shape. This is especially important around the neck, chest, and front legs.

A small embroidered patch adds personality to the sweatshirt.

The maker chose a mountain-themed design with the words “Adventure Awaits.”

The patch was positioned on the back panel, creating a simple outdoor-inspired look against the muted sage-green fabric.

The project photos show the decorative detail on the fabric, while the additional footage documents part of the pressing process.

If you're adding a similar decoration, plan its position before the garment is fully assembled.

Make sure the patch is securely attached and doesn't create a stiff or uncomfortable area against the dog's body.

The sweatshirt uses a raglan-sleeve design, with seams extending from the underarm area toward the neckline.

This creates a distinctive shoulder shape and gives the finished garment a clean, structured appearance.

The maker used an overlock sewing machine (serger) during construction.

The sewing footage shows the fabric being joined, and the progress photos reveal the developing shape of the sweatshirt as the sleeves and body come together.

When sewing a similar garment, match the corresponding pattern markings and follow the assembly order provided with your pattern.

Try not to stretch the fabric unevenly while sewing, especially when working with knit materials.

Before finishing the neckline and cuffs, check that the sleeve and chest areas allow enough room for the dog's natural movement.

For this version, the maker used the same main fabric for the neckline and sleeve cuffs.

The matching fabric gives the sweatshirt a consistent appearance, but it also presented a challenge.

Because the main fabric had limited stretch, the neckline and cuffs felt tighter than expected.

The owner also felt that the seam allowance was rather narrow and plans to review it for the next version.

For a future sweatshirt, she would like to:

1. Try rib-knit fabric for the neckline.
2. Use more flexible rib-knit sleeve cuffs.
3. Choose a softer main fabric with better stretch.
4. Review the seam allowance before cutting.
5. Make a test garment to check the fit.

These adjustments may help improve comfort and make dressing easier.

Remember that seam allowances and wearing ease are different things. Simply adding more seam allowance does not necessarily make a finished garment larger. Any adjustment should take the pattern's original construction into account.

Time for the best part: trying the finished sweatshirt on the little Schnauzer!

The completed outfit features long raglan sleeves, matching cuffs, a curved back hem, and the embroidered mountain patch.

The owner loved the three-dimensional silhouette and overall appearance of the pattern.

Although she felt that the sweatshirt looked slightly small and the neckline and cuffs were snug, she reported that her puppy could still walk, move, play, and go to the bathroom naturally without showing signs of discomfort.

The photos show the sweatshirt from several angles, including the front, side, and back.

When fitting clothes on a dog, always watch for signs of discomfort or restricted movement. Check the neckline, chest, sleeves, and leg openings carefully.

A garment should never interfere with breathing, walking, playing, or normal bathroom activities.

This project turned a printable sewing pattern into a real sweatshirt for a young Miniature Schnauzer.

The maker was pleased with the structured shape and overall appearance of the finished garment. She also shared some valuable feedback about the pattern layout, fabric choice, seam allowances, and fit.

What worked well:

1. The pattern produced an attractive three-dimensional shape.
2. The finished sweatshirt had a clean raglan-sleeve silhouette.
3. The owner reported that the puppy could move and play naturally.
4. The project provided a useful starting point for another version.

What could be improved:

1. A more compact printed pattern layout.
2. Reviewing the seam allowance.
3. Choosing a softer, stretchier main fabric.
4. Using rib-knit material for the neckline and sleeve cuffs.
5. Making another test garment to refine the fit.

Every sewing project offers an opportunity to learn.

Digital patterns can simplify the preparation process, but the final result still depends on fabric selection, construction techniques, and real-world fitting.
