How to Choose the Right Size for Your Pet
Finding the right size for your pet can make a big difference in their comfort, safety, and overall experience with a product. Whether you're shopping for clothing, a harness, bedding, or another pet essential, choosing based on appearance alone isn't always enough. How to Choose
Every pet has a different body shape, and size can vary between breeds, ages, and even individual pets. That's why taking a few simple measurements before ordering is one of the best ways to find the right fit.
Here's how to do How to Choose.
Why the Right Fit Matters
A product that's too small can feel restrictive and uncomfortable, while something that's too large may move around, slip off, or prevent your pet from moving naturally.
The right fit should allow your pet to move, sit, lie down, and play comfortably without unnecessary pressure or restriction.
For clothing and wearable products especially, a proper fit can help prevent rubbing, chafing, or discomfort.
What You'll Need
You don't need anything complicated to measure your pet. How to Choose
A soft measuring tape is ideal, but if you don't have one, you can use a piece of string and measure it afterward with a ruler or standard tape measure.
Keep your pet standing naturally while taking measurements. Avoid pulling the tape too tightly.
1. Measure Your Pet's Neck
Place the measuring tape around the base of your pet's neck, where a collar would naturally sit.
The tape should be comfortably snug without pressing into the skin.
For clothing or other products that fit around the neck, this measurement can help determine whether the opening will be comfortable.
Tip: You should generally be able to fit a couple of fingers comfortably between the tape and your pet's neck.
2. Measure the Chest
The chest measurement is particularly important for clothing, harnesses, and other products that fit around your pet's body.
Wrap the measuring tape around the widest part of your pet's chest, usually just behind the front legs.
Make sure the tape stays level and isn't pulled tightly against the body.
This measurement is often more useful than weight alone because pets of the same weight can have very different body shapes.
3. Measure the Back Length
For clothing, coats, sweaters, and similar products, you'll usually need your pet's back length.
Measure from the base of the neck to the base of the tail, following the natural line of the back.
Don't include the tail in the measurement.
Try to keep your pet standing naturally rather than sitting or lying down while you measure.
4. Check the Product's Size Guide
Once you have your measurements, compare them with the size chart provided for the specific product you're purchasing.
Don't assume that a small, medium, or large size will be the same across every product.
Different manufacturers and product designs can use different sizing standards, so always check the individual product's measurements before placing your order.
Weight Can Help — But Don't Rely on It Alone
Some pet products provide recommended weight ranges for each size.
Weight can be useful as a general reference, but it shouldn't always be your only measurement.
For example, two dogs may weigh the same but have completely different chest measurements, body lengths, or proportions.
When a product's size guide includes measurements, prioritize your pet's actual measurements when deciding which size to purchase.
What If Your Pet Is Between Sizes?
If your pet's measurements fall between two available sizes, look carefully at the product's size guide and consider how the product is designed to fit.
For clothing and wearable products, you generally want enough room for comfortable movement without the item being excessively loose.
For beds, carriers, and other products where interior space matters, consider your pet's sleeping or resting position and how much room they need to move comfortably.
When in doubt, check the specific product's recommendations or contact Oddly Pets before ordering.
Consider Your Pet's Shape
Measurements don't tell the entire story.
Your pet's breed, body shape, fur thickness, age, and proportions can all affect how a product fits.
A pet with thick or long fur may need additional room in certain clothing or wearable products. Similarly, pets with broader chests or longer bodies may not fit standard proportions in the same way as pets with slimmer builds.
That's why measuring your individual pet is always better than relying solely on breed or weight.
Measure Before Every Major Purchase
Pets can change size over time.
Puppies and kittens grow quickly, while adult pets can also gain or lose weight or experience changes in body shape.
If it's been a while since you last measured your pet, take fresh measurements before purchasing a new size.
This is especially important when buying clothing, harnesses, carriers, or other products where fit directly affects comfort.
A Quick Measurement Checklist
Before ordering, make sure you have:
- Your pet's neck measurement
- Your pet's chest measurement
- Your pet's back length
- Your pet's current weight, if requested by the product
- The specific product's size chart
- Any product-specific fitting instructions
Take your time and double-check your measurements before selecting a size.
Comfort Comes First
The best size isn't necessarily the smallest size that fits. Your pet should be able to move naturally and remain comfortable while using or wearing the product.
After receiving an item, check the fit before allowing your pet to use it for an extended period. Look for signs that the product is too tight, too loose, rubbing against the skin, or restricting movement.
If something doesn't look or feel right, stop using it and review the product's fitting instructions and return options.
