As a proud dog owner, you want to spoil your four-legged friend with the best accessories. But did you know a well-fitting collar is essential for your dog’s comfort? Find out how to measure the correct collar size here!
When is a collar too tight?
A collar should have a good fit, but knowing when it is tight is essential. Pay close attention to signs such as rubbing, redness or irritation around your dog’s neck. If your furry friend has trouble breathing or is uncomfortable wearing the collar, it’s probably too tight. Give your dog room to move and play freely to ensure the collar is not tight.
The right size collar ensures that your dog can move, play, and run freely without any restrictions. It also gives you peace of mind during walks. In short: the right size is important for both comfort and safety.
What is the ideal size?
Determining the ideal size for your dog’s collar is essential for his comfort. The size is determined by the circumference of your dog’s neck. Take a measuring tape and carefully wrap it around the neck below the jawline. Make sure the fluff isn’t too loose by holding two fingers between your dog’s neck and the measuring tape. Please read the measurement carefully to get an accurate size. Remember that every dog is unique, so meet regularly, especially if your dog is still growing. Determining the ideal size ensures that the collar is comfortable and does not chafe or kneel.
Start by finding the right spot on your dog’s neck. This is the widest part of the neck, just below the jawline and above the shoulders. Take your flexible measuring tape and gently wrap it around your dog’s neck.
Here’s the most important tip: keep two fingers between the neck and the measuring tape. This will give you the perfect fit—not too tight, not too loose. Read the measurement in centimeters and write down the number. This is your dog’s neck circumference. Not sure? Always choose the larger size and adjust the collar with the buckle.



The ideal collar for every dog
Determining the ideal size for your dog’s collar is essential for his comfort. The size is determined by the circumference of your dog’s neck. Take a measuring tape and carefully wrap it around the neck below the jawline. Make sure the fluff isn’t too loose by holding two fingers between your dog’s neck and the measuring tape. Please read the measurement carefully to get an accurate size. Remember that every dog is unique, so meet regularly, especially if your dog is still growing. Determining the ideal size ensures that the collar is comfortable and does not chafe or kneel.
Take, for example, the TRIX collar, made from recycled polyester derived from PET bottles and finished with vegan leather. Or choose the stylish BO vegan leather collar, available in four beautiful colors: mauve mist, emerald, coral, and gray. The buckle is sturdy and reliable, and the collar is soft on the inside, even for dogs with sensitive coats
Collar size: What size does your dog need?
Most collars come in standard sizes such as S, M, L, and XL. That’s where the size chart comes in! A good size chart helps you convert the measured circumference to the correct size. At PAWNESS, you’ll find a clear size chart with all the information you need for every product.
For example, size M is suitable for medium-sized dogs with a neck circumference of approximately 35–45 centimeters. But keep in mind: every breed is different! A dachshund wearing a size M collar has a different build than a beagle wearing the same size. Use a flexible measuring tape and take your time to get it right.
Also take your dog’s coat into account. Dogs with thick coats sometimes need a larger size than you might expect. Therefore, always measure directly against the skin, not over the coat.
When is a collar too tight?
A collar should have a good fit, but knowing when it is tight is essential. Pay close attention to signs such as rubbing, redness or irritation around your dog’s neck. If your furry friend has trouble breathing or is uncomfortable wearing the collar, it’s probably too tight. Give your dog room to move and play freely to ensure the collar is not tight.
Another indication is if you can’t fit two fingers between the collar and the neck. This means the collar is too tight and your dog doesn’t have enough room to move comfortably. Difficulty breathing is also a clear sign.
If the buckle is all the way in the last hole and the collar still doesn’t fit properly, it’s time for a new collar in a larger size.


Measuring Your Dog’s Neck: Extra Tips
Measuring your dog’s neck can sometimes be a challenge, especially if you have an energetic four-legged friend who can’t sit still! Choose a quiet moment, such as after a long walk or during a cuddle session on the couch. You might want to give your dog a tasty treat to keep him calm while you measure.
Take your dog’s growth into account. If you have a puppy, remeasure regularly. Puppies grow quickly and will soon need a larger size. Consider choosing a collar with multiple holes so you can adjust it as your dog grows. Also keep your dog’s breed in mind. Some dog breeds, such as the dachshund, have a unique body structure.
From Old Collar to New Collar
Maybe your dog already has a collar and you’re looking for a new one. In that case, you can use the current collar as a reference! Grab the old collar and see which hole you usually use. Measure the length of the collar from the buckle to that hole.
But be careful: if the old collar didn’t fit well, don’t use it as your only reference. Measure your dog’s neck again to make sure you choose the right size. Also check the condition of the current collar. Is it stretched out or worn? If so, the size may no longer be accurate. If you’re unsure between two sizes, go with the larger one.
