By comparing your dog’s measurements to our size chart, you’ll make sure their gear fits just right—and works the way it should. The right size means maximum comfort, freedom to move, and protection from the elements. Best of all, you avoid the hassle of returns and get straight to spending quality time with your best friend.

Choosing a shell jacket that needs room for a mid-layer? Go for the larger size. Picking an active dog overall? Opt for the smaller size so it fits snugly and stays in place.

For jackets, we recommend sizing up—Hurtta gear has excellent adjustability. Especially with the back length adjustment, the jacket will stay securely in place without limiting movement or leaving gaps.

When selecting the right size for your dog, their body shape plays a crucial role. Always prioritize comfort and adjustability, especially when your dog’s body type falls outside standard sizing options.

Slim or lean dogs
Choose a smaller size for a snug, secure fit—without excess fabric. This prevents shifting or sliding during walks and play.

Muscular or broad dogs
Go up a size to allow room around the chest and neck without restricting movement. Check the size chart for XL options to ensure comfort.

Fur type
Short-haired dogs typically need less room in their gear. Long- or thick-furred dogs may need more space, especially in colder months when the fur is fuller. If your dog is trimmed for summer, consider sizing accordingly for seasonal changes.

❌ Don’t rely only on breed recommendations:
These are general guidelines. Dogs of the same breed can vary a lot, so measuring your own dog is always the best approach.

❌ Don’t size up “just in case”:
It’s tempting—especially with puppies—but extra room often leads to poor fit and discomfort. Choose the correct size and adjust as your dog grows.

❌ Don’t skip key measurements:
Some products prioritize specific measurements, like chest girth for harnesses or back length for jackets. Ignoring these may result in a poor fit.

❌ Don’t assume sizes are consistent across products:
Different models and materials may fit differently. Always check the product-specific size chart to ensure the best fit for your dog.

Some Hurtta products come in special sizes designed for specific breeds. These are marked with a letter after the size number—so you know it’s tailored to fit your dog’s unique shape.

Our size charts are based on measurements from thousands of dogs across hundreds of breeds. With years of data, we can offer helpful breed-based size recommendations. But every dog is an individual—and even within breeds, body types vary a lot. That’s why measuring is the most reliable way to find the perfect fit for your unique fur ball.
