Signs Your Dog’s Collar Doesn’t Fit Properly

A dog collar can look perfectly normal from across the room and still fit incorrectly.

Maybe it's slightly too tight.

Maybe it's loose enough to rotate constantly.

Maybe your puppy has grown since you last adjusted it.

Or perhaps a recent haircut changed how the collar sits around your dog's neck.

Because dogs can't tell us, “My collar feels a little tight today,” it's important to know what to look for.

A properly fitted collar should feel secure without being restrictive.

It shouldn't press tightly into the neck.

But it also shouldn't hang so loosely that it constantly slides, rotates, or looks capable of slipping over the dog's head.

Here are the most common signs that your dog's collar may not fit properly—and what you can do about them.

1. You Can't Comfortably Fit Your Fingers Under the Collar

One of the easiest ways to check collar fit is with your fingers.

A commonly used starting point is the two-finger rule.

You should generally be able to slide approximately two fingers between your dog's collar and neck.

If you struggle to get your fingers underneath, the collar may be too tight.

If you can fit several fingers underneath with lots of extra space, it may be too loose.

Remember that the two-finger method is a general guideline rather than a substitute for checking your individual dog's comfort, body shape, and collar design.

2. The Collar Leaves Deep Marks in the Fur

It's normal for a collar to slightly change the direction of your dog's fur.

But when you remove it, look at the neck.

If you consistently see a pronounced indentation or compressed area, check the fit carefully.

This can be especially easy to miss on:

Long-haired dogs
Thick-coated dogs
Fluffy breeds

The outside appearance of the coat doesn't always tell you what's happening underneath.

Use your fingers to check the actual collar-to-neck fit.

3. You Notice Redness or Irritated Skin

Regularly check the skin underneath your dog's collar.

Look for:

Redness
Irritation
Sensitive areas
Chafing
Unusual hair loss
Broken skin

These signs don't automatically mean collar tightness is the only cause. Moisture, friction, allergies, skin conditions, debris, or the collar material may also contribute.

But they are a reason to investigate rather than simply ignoring the area.

If irritation persists, becomes painful, develops an odor or discharge, or otherwise concerns you, consult your veterinarian.

4. Your Dog Frequently Scratches Around the Collar

Dogs scratch for many reasons.

One occasional scratch isn't necessarily meaningful.

But if your dog suddenly begins repeatedly scratching around the neck after:

Getting a new collar
Changing collar size
Adjusting the collar
Adding a decorative accessory

check the fit.

Also inspect underneath the collar for:

Tangled fur
Debris
Moisture
Skin irritation
Anything caught between the collar and neck

If frequent scratching continues even after checking the collar, speak with your veterinarian.

5. The Collar Constantly Rotates Around the Neck

Now we're moving from signs of a potentially tight collar to a potentially loose one.

If the collar continually rotates around the neck during normal movement, check the adjustment.

Some movement is completely normal.

Dogs:

Walk
Run
Shake
Scratch
Turn their heads
Lie down

A collar isn't expected to remain perfectly stationary.

But excessive rotation can indicate too much extra room.

6. The Buckle Keeps Moving to the Front

You put the collar on correctly.

Ten minutes later, the buckle is sitting underneath your dog's chin.

This can happen occasionally because of normal movement.

But if it happens constantly, the collar may be rotating excessively.

Check:

Collar size + Adjustment + Neck shape

before assuming something is wrong with the buckle itself.

7. Your Dog's Bow Tie Never Stays Centered

If your dog wears a Bow Tie Collar, the accessory can actually give you a visual clue about fit.

A Bow Tie will naturally move somewhat.

But if it constantly travels from:

Center → Side → Back of neck

the entire collar may be rotating.

Before repeatedly moving the Bow Tie back into place, check the underlying collar fit.

A properly adjusted collar can make it easier to keep decorative accessories positioned—but never overtighten a collar simply to hold a Bow Tie in place.

8. The Collar Looks Like It Could Slip Over the Head

A collar that's too loose may potentially slip over the dog's head, depending on the dog's anatomy and collar design.

This is particularly important for dogs whose:

Head and neck measurements are relatively similar.

Check the collar carefully rather than relying only on how it looks from the side.

If you're uncertain about secure walking equipment for your dog's particular body shape or behavior, ask your veterinarian or a qualified trainer for guidance.

9. Your Dog Can Get a Paw Under the Collar

If there's enough space for your dog to repeatedly get a paw underneath the collar, check whether the collar is too loose.

This can be uncomfortable and potentially create a safety issue.

Don't respond by dramatically tightening it.

Instead:

Measure your dog's neck.
Check the collar's size range.
Readjust it appropriately.
Recheck the fit.

If the collar can't be adjusted appropriately, you may need a different size.

10. Your Dog Tries to Remove the Collar

A dog pawing at a collar doesn't automatically mean it's too tight.

Dogs may react to:

A new collar
An unfamiliar accessory
A different material
Tags
Decorative pieces
Something caught underneath

But repeated attempts to remove the collar deserve attention.

Take it off and inspect:

The collar + Fur + Skin + Fit

before putting it back on.

11. The Collar Seems to Interfere with Normal Movement

Watch your dog naturally.

They should be able to:

Turn their head
Look up
Look down
Sit
Lie down
Walk comfortably

without the collar obviously interfering.

If an accessory is particularly large, also check that it doesn't interfere with the dog's jaw or natural head movement.

A collar should complement normal movement—not restrict it.

12. Your Dog Acts Differently After You Tighten the Collar

Pay attention to changes in behavior.

If your dog seems comfortable before an adjustment but becomes noticeably uncomfortable afterward, recheck what you changed.

Possible signs can include:

Increased scratching
Pawing at the neck
Reluctance to move normally
Repeated attempts to remove the collar
Unusual sensitivity around the neck

If your dog appears distressed or has difficulty breathing, remove pressure from the neck immediately when safe and seek veterinary care.

13. The Collar Has Reached Its Maximum Adjustment

Suppose your dog's collar is adjusted to the very end of its usable range.

Technically, it may still go around the neck.

But that doesn't necessarily mean it's the best size.

A collar should provide a practical adjustment range rather than barely fitting at its absolute limit.

If your dog has outgrown the comfortable adjustment range, measure again and consider the next appropriate size.

14. The Collar Is at Its Smallest Setting but Still Loose

The opposite problem can happen too.

If you've adjusted the collar as small as it can go and it still rotates excessively or hangs away from the neck, the collar may simply be too large.

In that case, tightening isn't possible.

You likely need a smaller size.

15. Your Puppy Has Grown

Puppies can outgrow collars surprisingly quickly.

A collar that fitted perfectly several weeks ago may now be too tight.

Don't rely on memory.

Check puppy collar fit frequently as they grow.

A quick finger check takes seconds.

Periodically measuring the neck gives you even more confidence.

16. Your Dog Has Gained or Lost Weight

Changes in body weight can affect neck circumference.

If your dog has experienced a noticeable weight change, don't assume the existing collar adjustment is still correct.

Measure again.

This is particularly important after significant weight changes.

If weight change is unexpected or concerning, discuss it with your veterinarian as well.

17. Grooming Changed the Fit

This is especially common with long-haired dogs.

Before grooming:

Thick coat around neck

After grooming:

Much less volume

The same collar can suddenly feel noticeably looser.

The reverse can also happen as a thick coat grows back.

After a substantial haircut or seasonal coat change:

Recheck the collar.

18. Long Hair Can Hide a Poor Fit

Looking at the collar from the outside isn't enough for a fluffy dog.

The coat may make the collar appear snug even when there's substantial space underneath.

Or thick fur may make it look tight when the actual neck fit is appropriate.

Use your fingers.

Check underneath the coat.

You're fitting the collar to the dog's neck, not to the outer edge of the fur.

19. Short Hair Makes Pressure Easier to See

With short-haired dogs, fit problems may be more visible.

You may notice:

Pressure marks
Redness
Rubbing
Collar position

more easily.

Use that visibility to your advantage.

Check the neck regularly when putting on or removing the collar.

20. The Collar Looks Disproportionately Wide

Fit isn't only about circumference.

Collar width also matters.

An extremely wide collar on a tiny neck can look and feel very different from a narrower collar designed for smaller dogs.

That's why LA Dog Store uses different widths across its size range.

LA Dog Store Collar Size Chart

Size	Neck Size	Collar Width
XS	6–8" (15–20 cm)	3/8" (1.0 cm)
S	8–11" (20–28 cm)	3/4" (2.0 cm)
M	11–14" (28–36 cm)	1" (2.5 cm)
L	14–18" (36–46 cm)	1" (2.5 cm)
XL	18–22" (46–56 cm)	1" (2.5 cm)
XXL	22–26" (56–66 cm)	1.5" (3.8 cm)

Sizing Tip: Measure your dog's neck before ordering. If your dog falls between sizes, size up.

How to Measure Your Dog's Neck Correctly

If you suspect the collar doesn't fit, start over with a fresh measurement.

Use a flexible measuring tape.

Step 1

Have your dog stand or sit naturally.

Step 2

Wrap the measuring tape around the area where the collar normally sits.

Step 3

Keep the tape snug without pulling it tightly into the neck.

Step 4

Record the measurement.

Step 5

Measure again.

Two quick measurements can help catch a simple mistake.

Step 6

Compare the number with the specific collar's size chart.

Don't select size based only on breed, weight, or the size your dog wears from another brand.

Don't Assume Collar Sizes Are Universal

One company's Medium may be another company's Large.

Size labels such as:

XS, S, M, L, XL and XXL

aren't universal measurements.

Always compare the actual neck range.

For LA Dog Store, for example:

Medium = 11–14 inches

But that doesn't mean every Medium dog collar sold elsewhere uses the same range.

Measurement matters more than the letter.

The Two-Finger Rule: Useful, but Don't Stop There

The two-finger rule is a convenient starting point.

But also ask:

Does the collar remain secure?

Is my dog moving comfortably?

Is there rubbing underneath?

Does it rotate excessively?

Has my dog's neck size changed?

Does the collar design suit my dog's anatomy?

Fit is a combination of measurements and observation.

Too Tight vs. Too Loose: Quick Comparison

Possible Sign	Too Tight	Too Loose
Difficult to fit fingers underneath	✓
Pressure or rubbing	✓
Redness under collar	✓
Collar constantly rotating		✓
Buckle repeatedly moves around neck		✓
Bow Tie constantly moves sideways		✓
Paw can repeatedly get underneath		✓
Appears capable of slipping over head		✓
Dog frequently paws at collar	Possible	Possible
Collar at adjustment limit	Possible	Possible

Remember: some signs can have multiple causes.

Use them as clues—not as a diagnosis.

What If the Collar Fits but Your Dog Still Seems Uncomfortable?

Don't assume every neck problem is a sizing problem.

Possible causes can include:

Skin sensitivity
Allergies
Moisture
Dirt or debris
Matted fur
Hardware irritation
Skin conditions
Another medical issue

Remove the collar when appropriate and inspect both the collar and the neck.

Persistent redness, sores, swelling, significant hair loss, pain, or other concerning symptoms should be evaluated by a veterinarian.

Check Under Decorative Accessories Too

If your dog wears a:

Bow Tie

Flower Bow Tie

Floral Collar

don't check only the plain section of the collar.

Look around the decorative area too.

Make sure:

Fur isn't trapped
Flowers aren't pressing awkwardly
The Bow Tie isn't interfering with movement
Nothing is rubbing the skin
The accessory hasn't shifted into an uncomfortable position

Style and comfort should work together.

Never Tighten a Collar Just for Better Photos

This deserves its own section.

If your dog's Bow Tie keeps rotating, don't solve the problem by making the collar uncomfortably tight.

Instead:

Check the collar size
Check the adjustment
Center the Bow Tie before the photo
Arrange the fur
Reposition after movement

A perfectly centered accessory isn't worth compromising fit.

How Often Should You Check Collar Fit?

There's no single schedule for every dog.

Check more frequently when:

Your dog is a growing puppy
Your dog's weight changes
Coat thickness changes
Your dog has been groomed
You switch collars
You add a decorative accessory
You notice scratching or rubbing
The collar suddenly starts rotating more than usual

It takes only a few seconds.

A 30-Second Collar Fit Check

Want something easy to remember?

Do this:

1. Fingers

Can you comfortably slide approximately two fingers underneath?

2. Skin

Any redness, rubbing, or irritation?

3. Movement

Can your dog move their head naturally?

4. Rotation

Is the collar excessively loose?

5. Adjustment

Is there still a reasonable adjustment range?

6. Accessory

Is the Bow Tie or floral detail sitting comfortably?

Thirty seconds can tell you a lot.

When Should You Measure Again?

Measure your dog's neck again if:

✓ You're buying a new collar

✓ Your puppy is growing

✓ Your dog gained or lost weight

✓ Your dog had a significant haircut

✓ The coat has changed seasonally

✓ The existing collar suddenly feels different

✓ You're unsure about the current size

Guessing takes longer than measuring.

Conclusion

A properly fitted dog collar should be something you barely have to think about.

It should sit securely around your dog's neck without pressing tightly or constantly sliding around.

Watch for warning signs such as:

Difficulty fitting your fingers underneath.

Redness or rubbing.

Frequent scratching.

Excessive collar rotation.

A buckle that constantly moves around the neck.

A collar that seems capable of slipping off.

A Bow Tie that never stays anywhere near the front.

Sometimes the solution is as simple as readjusting the collar.

Other times, your dog may need a different size.

And sometimes skin irritation or discomfort may have another cause entirely.

When in doubt:

Measure again.

Check the neck.

Check the collar.

Watch your dog's behavior.

Because when it comes to dog collars, the best-looking fit is also one that keeps comfort, security, and your individual dog's needs at the center of the decision.

Frequently Asked Questions

How do I know if my dog's collar is too tight?

Difficulty sliding approximately two fingers underneath, pressure marks, rubbing, redness, or signs of discomfort can indicate that the collar needs to be checked.

How do I know if my dog's collar is too loose?

Excessive rotation, a buckle that repeatedly moves around the neck, a dog getting a paw underneath, or a collar that appears capable of slipping over the head can indicate excessive looseness.

Should I be able to fit two fingers under my dog's collar?

The two-finger rule is a commonly used starting guideline. You should generally be able to slide approximately two fingers comfortably between the collar and neck, while also checking overall security and your dog's individual anatomy.

Why does my dog's collar keep rotating?

The collar may be too loose, although neck shape, coat type, movement, and collar design can also affect rotation.

Why is my dog's Bow Tie always moving to the side?

The entire collar may be rotating. Check the collar size and adjustment before trying to solve the problem by tightening it excessively.

Can grooming change how my dog's collar fits?

Yes. Removing a substantial amount of fur can make a collar feel looser, while a thicker coat can change how it sits. Recheck the fit after significant grooming.

How often should I check my puppy's collar?

Check frequently because puppies can grow quickly. Don't assume a collar that fitted recently still fits correctly today.

Can a collar cause skin irritation?

Friction, moisture, debris, fit, material sensitivity, or underlying skin problems can all contribute to irritation. Persistent or significant symptoms should be evaluated by a veterinarian.

Should I choose my dog's collar size based on breed?

No. Measure the individual dog's neck and compare the measurement with the specific product's size chart.

What should I do if my dog's neck is between two LA Dog Store sizes?

For LA Dog Store collars, if your dog's neck measurement falls between sizes, size up.
