Dog Diaper Size Chart by Breed

Dog diapers aren’t the cutest topic to talk about, but when your dog needs them, they become a real life-saver. Whether your pup is in heat, has incontinence, or is recovering from surgery, a well-fitting dog diaper can make life easier for both of you.

For a while, I thought diapers were just for older dogs or emergencies, but I quickly learned that even young, energetic dogs sometimes need them too. One of my dogs had a tummy bug, and those few days with the wrong diaper size? A total mess literally. 

That’s when I realized just how important the right dog diaper size is. So to make things easy for you, let me help you find your dog diaper size by weight, breed, and gender.

Dog Diaper Size Chart by Breeds

One of the easiest ways to get an idea of which diaper might fit your dog is to consider their breed. While every dog is shaped a little differently, most brands offer a dog diaper size guide based on common breed types.

Toy breeds like Chihuahuas and Yorkies often wear XS or small sizes. Medium dogs like Cocker Spaniels or Beagles may fall in the medium to large range. Large breeds like Labs and German Shepherds usually need XL or XXL sizes.

Some dogs are lean with narrow waists, others are more round or muscular. Always measure your pup before buying, waist size is the most important number.

Dog Diaper Size Chart for Small Breed Dogs

Small dogs may seem easy to shop for, but finding the right pet diaper size can still be difficult especially if your dog is between sizes. For most small breed dogs, look for diapers that fit waists between 10 to 15 inches, depending on the brand.

If you’re shopping for a female dog diaper size, make sure there’s a snug fit around the tail area to avoid leaks. For males, belly bands may be a better fit for light coverage. Some good examples of small breeds that usually fall under this size are

• Maltese
• Dachshund
• Pomeranian
• Shih Tzu

Dog Diaper Size Chart for Medium Breed Dogs

Medium breed dogs can be a bit more varied in shape. You’ll find some slim and long (like Whippets) and others more round (like Bulldogs). Most reusable diapers or disposable diapers labeled “medium” will fit dogs with waists between 15 and 20 inches, and weights around 20 to 45 lbs.

Breeds that often fall into the category of Beagle, Cocker Spaniel, French Bulldog, Mini Australian Shepherd etc. With medium dogs, fit really matters. Stick with brands that offer adjustable straps or stretchy sides.

Dog Diaper Size Chart for Large Breed Dogs

Large breed dogs need full coverage and strong absorbency. Pet diaper sizes that fit waists over 20 inches and weights over 45 lbs usually fall into the “large” or “XL” categories.

These dogs need diapers that stay in place even when they move around or lie down. Look for options with strong fasteners and leak-proof edges. Both reusable diapers and disposable diapers work well; it just depends on your lifestyle and how often you’ll be changing them. For female dog diaper size, make sure there’s enough back coverage and flexibility, especially if they squat to pee.

How to Prevent Leaks and Messes with Dog Diapers

Even with the perfect dog diaper size, leaks can happen if the diaper isn’t on correctly or isn’t the right style for your dog’s body. Here are some simple tips to prevent that from happening:

• Always check the waist measurement and make sure the diaper sits right.
• For female dogs, a proper tail hole and secure fit around the hips are important.
• Use reusable diapers with extra padding or liners if your dog tends to pee more frequently.
• Trim long fur near the belly and tail to help the diaper sit properly.
• Choose disposable diapers with wetness indicators to know when it’s time for a change.

When to Use Dog Diapers: Situations You Might Not Expect

Dog diapers aren’t just for older dogs or females in heat. There are several situations where a diaper might be helpful even if just for a short time.

• Post-surgery recovery: Prevents licking or infection from open wounds.
• House-training puppies: Useful for short-term indoor use, especially when you’re away.
• Long car rides or travel: Diapers can prevent accidents on the go.
• Excited urination or submissive peeing: Common in some small breeds or anxious dogs.
• Dogs with disabilities or injuries: Helps manage daily needs with less stress.

FAQs

How do I choose between reusable and disposable dog diapers?

It depends on your routine. Disposable diapers are great for short-term use, like a heat cycle or recovery period. They’re easy to use and throw away. Reusable diapers are cost-effective for long-term use and more eco-friendly, especially if you wash them regularly.

What if my dog is between two diaper sizes?

 If you’re stuck between sizes, go with the larger one. A snug but not tight fit is important. You can always tighten a bigger diaper using the adjustable straps, but a small one can cause discomfort.

How do I know if a diaper fits properly?

The diaper should sit snugly around your dog’s waist without slipping down. There shouldn’t be any gaps around the legs or tail, especially with a female dog diaper size. It also shouldn’t leave red marks or indentations on their skin.

Are there special dog diaper sizes for puppies?

Yes, Many brands offer XS or “puppy” sizes. Just make sure to re-measure regularly because puppies grow fast, and what fits one month might be too small the next.

How often should I change my dog’s diaper?

At least every few hours or sooner if it’s soiled. Leaving a wet dog diaper on for too long can cause skin irritation or infection. Make sure to wash them thoroughly between uses.
