10 Dog Clothes From Old Shirts Tutorial
I have a confession: my dog’s wardrobe is bigger than mine. But buying new outfits for every season gets expensive fast. That is why I started looking in my own closet first. Old shirts, flannels, and button-ups can become the coziest, cutest clothes for your pup.
You do not need to be a sewing expert. Most of these projects use simple snips and a few basic stitches. Some you can even finish without a needle at all. Let me show you ten easy ways to turn your forgotten shirts into something your dog will actually love wearing.
Grab an old shirt from your donation pile and let’s make something fun together.

1. The No-Sew Bandana from a Button-Up Collar
This is the easiest project to start with. Take an old button-up shirt and cut off the collar. Keep the collar band intact. That little piece of fabric with the button is already shaped perfectly to tie around your dog’s neck.
Cut a triangle shape from the shirt’s back. Attach it to the collar band with fabric glue or just tie it on. You get a bandana that looks store-bought but cost zero dollars.
My dog wears this on walks and it stays put. No slipping, no fussing.

2. Sleeve Sweater for Small Breeds
Old long-sleeve shirts have the perfect tube shape for tiny dogs. Cut off one sleeve at the shoulder seam. Measure from your dog’s neck to their belly. Cut the sleeve to that length.
Fold over the raw edge at the neck and make a small hem. Cut two small holes near the fold for a ribbon or strip of fabric to act as a collar tie. That is it. The sleeve fits like a little sweater.
Works best for Chihuahuas, Yorkies, and other small pups who get chilly.

3. Flannel Shirt Jacket with Leg Holes
Flannel shirts are thick and warm. Lay the shirt flat and cut off both sleeves. Turn the shirt so the back faces up. Place it over your dog’s back. Mark where their front legs go.
Cut small slits for the legs. Hem the edges or leave them raw if the fabric does not fray. The buttons go under the belly. You can button it up for a snug fit or leave it open for a cape look.
This one keeps my dog warm during fall hikes.

4. T-Shirt Tube Top for Summer
Cotton t-shirts are soft and breathable. Cut a wide band from the bottom hem of the shirt. This band already has a finished edge on one side. Fold it in half lengthwise.
Slip it over your dog’s chest. It acts like a lightweight tube top. It covers their back and belly without being too hot. You can add a small strap between the front legs to keep it from sliding up.
Perfect for short walks on warm days or for dogs with sensitive skin.

5. Hoodie from a Hooded Sweatshirt
If you have an old hoodie with a stretched out neck, save the hood. Cut the hood off the sweatshirt. Turn it upside down. The rounded top becomes a little hood for your dog’s head.
Cut two armholes on the sides for the front legs. The bottom edge of the hood becomes the neck opening. You can add a drawstring to tighten it if needed.
My dog looks hilarious in this, but it keeps their ears warm in winter.

6. Polo Shirt Polo Vest
Polo shirts have a nice structured collar. Cut off the sleeves. Cut the body shorter so it ends at your dog’s belly. Leave the front buttons open so it hangs like a vest.
You can sew a small piece of elastic across the chest to keep it in place. The collar stands up nicely and gives your dog a preppy look. It is great for dogs who do not like full coverage but need a little warmth.
I use this for quick potty breaks in chilly weather.

7. Button-Up Belly Wrap
This one is for dogs who need belly coverage. Take a button-up shirt and cut off the sleeves. Cut the shirt in half horizontally. Use the bottom half with the buttons.
Wrap it around your dog’s belly with the buttons facing down. The buttons let you adjust the fit. It covers the belly but leaves the back open. Great for dogs with belly rashes or after surgery.
It stays in place surprisingly well.

8. Denim Shirt Durability Vest
Denim shirts are tough. Cut off the collar and sleeves. Cut the body into a vest shape that wraps around your dog’s chest. Use the existing button placket for closure.
Denim does not stretch, so measure carefully. Add a little extra room. The thick fabric protects your dog from bushes and rough terrain. It also looks incredibly cool.
My dog wears this on trail runs and it has held up for over a year.

9. Silk Shirt Dress-Up Cape
Got a silky blouse you never wear? Cut off the front panel. Cut it into a cape shape that drapes over your dog’s back. Attach a ribbon at the neck to tie it on.
Silk slides easily and does not irritate fur. It is lightweight and fancy. Use this for photos, birthdays, or just because your dog deserves to feel like royalty.
It does not provide warmth, but it is pure fun.

10. Pocket T-Shirt Treat Carrier
Find a t-shirt with a chest pocket. Cut out the pocket plus an inch of fabric around it. Sew or glue a strip of fabric to each side so it becomes a little pouch.
Attach the pouch to a collar or a harness strap. Now your dog carries their own treats. It is not a garment exactly, but it is wearable and super useful.
We use this on every hike now. My dog knows when the pouch goes on, treats are coming.

Conclusion
Old shirts are not trash. They are fabric waiting for a second life. Every one of these projects takes less than an hour and costs nothing. Your dog does not care if the stitches are perfect. They care that you made something just for them.
Start with the easiest idea and see how it feels. You might end up with a whole new wardrobe for your pup and a lot less clutter in your closet.
Frequently Asked Questions
Do I need a sewing machine for these projects?
No. Most of these can be done with scissors and fabric glue. A needle and thread help for some, but you can skip it if you want.
What kind of shirts work best?
Cotton and flannel are easiest to cut and sew. Stretchy knits work too but can be trickier. Avoid stiff fabrics like heavy denim for small dogs.
How do I measure my dog for a shirt?
Measure around the chest behind the front legs and from the neck to the tail base. Use those numbers to decide where to cut.
Will my dog actually wear these?
Most dogs adjust quickly if the fit is not too tight. Start with short wearing times and offer treats. Some dogs love clothes from day one.
Can I wash these homemade dog clothes?
Yes. Machine wash gentle and air dry. They hold up better than you expect. Raw edges might fray a little, but that adds character.
