What Size Collar Should I Get For A Corgi Puppy?

Getting the right collar for your Corgi puppy is one of those small details that makes a big difference in your daily life together. A collar that fits properly keeps your puppy safe, comfortable, and ready for walks and training from day one. But Corgis have a unique body shape that can make collar sizing a bit tricky, especially when they are still growing.

What Size Collar Does a Corgi Puppy Need?

Most Corgi puppies start with a collar in the 8 to 12 inch range. When your Corgi first comes home at around 8 weeks old, their neck will typically measure about 8 to 10 inches around. By 4 to 6 months, expect the neck to measure around 10 to 14 inches. A fully grown adult Corgi usually needs a collar between 12 and 16 inches, though this varies based on the individual dog and whether you have a Pembroke Welsh Corgi or a Cardigan Welsh Corgi (Cardigans tend to be slightly larger).

Because puppies grow quickly, an adjustable collar with several inches of size range is the most practical choice. You will likely go through 2 to 3 collars before your Corgi reaches their adult size. Buying a collar that is too big and trying to “grow into it” is not safe because a loose collar can slip over a Corgi’s head, especially since their heads are not much wider than their necks.

How to Measure Your Corgi Puppy’s Neck

To get an accurate measurement, wrap a soft measuring tape around the middle of your puppy’s neck, where the collar would naturally sit. Do not pull it tight. You want a snug measurement that sits flat against the fur without compressing it. Once you have that number, add 2 inches. This gives your puppy enough room to be comfortable while keeping the collar secure enough that it will not slip off.

The general rule for a properly fitting collar is the two finger test. You should be able to slide two fingers between the collar and your puppy’s neck. If you can fit more than two fingers, the collar is too loose and could slip off or get caught on something. If you cannot fit two fingers, the collar is too tight and needs to be loosened or replaced with a larger size. Check the fit at least once a week during the puppy stage because Corgi puppies grow faster than you might expect.

Best Types of Collars for Corgis

Flat Buckle Collar

A standard flat buckle collar is the best everyday collar for most Corgi puppies. It is simple, comfortable, and provides a place to attach ID tags and a leash. Look for one made from nylon or leather with a sturdy buckle or snap closure. For puppies, a lightweight nylon collar is usually the most comfortable option. This is the collar your Corgi should wear day to day for identification purposes.

Martingale Collar

Martingale collars are an excellent choice for Corgis because of their body shape. Corgis have relatively narrow heads compared to their necks, which means a standard collar can sometimes slip over their head if they pull backward. A martingale collar tightens slightly when the dog pulls, preventing escape without choking. It is not a correction tool; it is a safety feature. Many Corgi owners consider a martingale their go to walking collar for this reason.

Harness

Because Corgis are low to the ground with long backs, a harness can be a better option than a collar for walks, especially if your Corgi tends to pull. A harness distributes pressure across the chest and shoulders rather than concentrating it on the neck, which is gentler on your dog’s trachea and spine. For a breed already prone to back issues, this is an important consideration. A front clip harness is particularly useful for training loose leash walking because it gently redirects your dog toward you when they pull.

Collar Materials: What Works Best

Nylon collars are the most popular choice for puppies because they are affordable, lightweight, come in many colors and patterns, and are easy to clean. They hold up well to daily wear and are adjustable, which is important during the rapid growth phase. The downside is that lower quality nylon can fray over time and some dogs develop mild skin irritation from the material.

Leather collars are more durable and tend to be gentler on the coat. They get softer and more comfortable with age, and a good leather collar can last for years. The downside is cost and the fact that leather can be damaged by water, which is something to consider if your Corgi loves playing in water. Biothane collars offer a nice middle ground. They look like leather but are waterproof, easy to clean, and extremely durable.

Collar Width Matters for Corgis

For Corgi puppies, a collar width of about 3/8 to 5/8 inch is appropriate. As your Corgi grows into an adult, a 3/4 to 1 inch wide collar works well. Avoid very narrow collars (less than 3/8 inch) because they concentrate pressure on a smaller area and can dig into the neck. Also avoid very wide collars on puppies because they can be uncomfortable and restrict movement on a small neck.

Collar Safety Tips for Corgi Puppies

Always remove your puppy’s collar during crate time. Collars can get caught on crate wires and create a strangulation hazard. Use a breakaway collar if your Corgi puppy spends time in a yard or plays with other dogs. These collars are designed to release under pressure, preventing choking if the collar gets caught on something.

Replace the collar as your puppy grows rather than trying to make an old one work. A collar that is even slightly too tight can cause skin irritation, restrict breathing, and be generally uncomfortable for your dog. A collar that is too loose can slip off at the worst possible moment, like near a busy road or in an unfamiliar area. Make sure your puppy’s ID tags and microchip information are always up to date on whatever collar they are wearing.

Introduce the collar gradually when your puppy first comes home. Let them sniff it, then put it on for short periods and distract them with treats and play. Most puppies get used to wearing a collar within a few days. If your puppy scratches at the collar constantly, check the fit and make sure the material is not irritating their skin.
