One of the first things you’ll need to do when you get a new puppy is to buy a collar and ID tags. But what size should you get? That will depend on the breed of your puppy and how big you think he’ll eventually be.

For most Labradors, a medium size will do just fine. You can always adjust it as he grows. Just make sure the collar is not too loose or too tight. You should be able to fit two fingers under the collar comfortably.

ID tags are important in case your puppy ever gets lost. Make sure his name and your contact information are clearly legible.

The Right Size is Important

Picking the right size collar for your Lab puppy is important for their safety and comfort. If the collar is too loose, they may be able to slip out of it and get lost. If it’s too tight, it could choke them or cut into their skin. You’ll need to measure your puppy’s neck before you can buy a collar that will fit them properly.

To measure your puppy’s neck, use a soft tape measure. Place the tape around their neck, just behind their ears. Make sure not to pull the tape too tight, or you’ll end up with an inaccurate measurement. Once you have the measurement, add two inches to account for any future growth. This is the size collar you should buy for your puppy.

You should also consider buying a collar that has an adjustable band. This will allow you to adjust the size as your puppy grows, so you don’t have to keep buying new collars. It’s a good investment that will save you money in the long run.

How to Measure Your Puppy

It’s important to get the sizing right when choosing a collar for your puppy – one that’s too big could slip off and get lost, while one that’s too small could be uncomfortable and restrictive. The best way to ensure a perfect fit is to measure your puppy’s neck using a flexible tape measure.

To do this, simply wrap the tape measure around the widest part of your puppy’s neck, making sure not to pull too tight. Once you have the measurement, add two inches to allow for some wiggle room and refer to our size chart to find the right collar size.

If you don’t have a tape measure or can’t get an accurate measurement of your puppy’s neck, you can also use a string or piece of ribbon. Simply wrap this around your puppy’s neck in the same way as you would a tape measure and then use a ruler or yardstick to determine the length. Again, add two inches for some wiggle room and refer to our size chart.

The Best Collar for a Lab Puppy

As your Labrador puppy grows, so will his neck size. You’ll need to continually monitor his weight gain and neck size so you can adjust his collar accordingly. A good rule of thumb is to add 2 inches to his neck size every time he doubles his weight. For example, if your 8-week-old Lab weighs 16 pounds, his neck size is likely 18 inches. At 16 weeks, when he weighs 32 pounds, his neck size should be 22 inches.

There are a few different types of collars you can choose from for your Lab puppy. A nylon or leather strap collar is a good option for everyday wear. These collars are adjustable and can be easily taken on and off. For walks and hikes, a harness is a good choice. Harnesses distribute the pulling force evenly across the chest and help prevent tracheal collapses, which are common in short-nosed breeds like Labs.

As your pup grows, you’ll need to keep an eye on how tight his collar is. It should be snug but not too tight — you should be able to fit two fingers underneath it comfortably. If it’s too loose, he may be able to wiggle out of it; if it’s too tight, it may cut off circulation or rub his skin raw.


After taking all of this information into consideration, we believe that the best size collar for a lab puppy is one that is comfortable for them to wear and that will not choke them or rub their fur too much. In most cases, a medium or large size should work perfectly, but it is always best to err on the side of caution and get a collar that is slightly too big rather than one that is too small.
