How to Choose a Leather Dog Collar for a Puppy That Is Still Growing
Choosing a Leather Dog Collar for a Growing Puppy
Buying a leather dog collar for a puppy requires a slightly different approach than buying one for a fully grown dog. Puppies can change quickly, and a collar that fits correctly today may need adjustment or replacement as the dog's neck grows.
The goal should not be to buy an oversized collar and hope the puppy grows into it. Start with a leather dog collar that fits the puppy's current neck measurement correctly, then monitor the fit as the dog develops.
Saddle Online Shop / TOMAR'S offers Small, Medium, and Large buffalo leather collars with different neck ranges and collar widths. Understanding those measurements makes it easier to choose a collar based on actual fit rather than breed predictions.
Measure Your Puppy's Neck First
Do not choose a collar simply because the product is labeled Small, Medium, or Large.
Measure around the part of the puppy's neck where the collar will normally sit. The measurement should reflect the puppy's current neck rather than an estimate of its eventual adult size.
If you have not measured before, follow our step-by-step dog neck measurement guide.
Our Leather Dog Collar Sizes
Our current buffalo leather collar lineup uses three sizes:
- Small: approximately 5"–8" neck | 3/4" wide | 12.5" overall leather length
- Medium: approximately 8.5"–11.25" neck | 1" wide | 15" overall leather length
- Large: approximately 11"–13.75" neck | 1.25" wide | 17.5" overall leather length
These dimensions matter more than the size name itself. Compare your puppy's actual measurement with the usable neck range rather than assuming a particular breed automatically belongs in one category.
See our complete Leather Dog Collar Size Guide for more information about sizing.
Should You Buy a Bigger Collar for a Puppy to Grow Into?
Buying substantially oversized dog gear simply to extend its useful life can create a poor fit in the meantime.
A collar needs to work for the dog wearing it now. If the puppy's neck is well below the intended adjustment range, moving up to the next size early is not a good substitute for proper fit.
As your puppy grows toward the upper end of the current collar's adjustment range, measure again and determine when the next size becomes appropriate.
Do Not Rely on Leather Stretch for Puppy Growth
Genuine leather can become more flexible through normal use, but that does not turn a Small collar into a Medium collar.
Do not intentionally buy a tight collar because you expect the leather to stretch as the puppy grows.
Our guide Do Leather Dog Collars Stretch? explains the difference between normal leather break-in and trying to use stretching as a sizing method.
How Often Should You Check a Puppy's Collar Fit?
A puppy deserves more frequent fit checks than a fully grown dog whose neck measurement has remained stable for years.
There is no single schedule appropriate for every puppy because growth rates vary. Instead, make collar fit part of your regular routine.
Check the collar whenever you notice:
- Rapid body growth
- A change in neck thickness
- The collar sitting differently than before
- The buckle moving progressively toward the final adjustment holes
- A significant coat change
- Changes in weight or body condition
When in doubt, measure the neck again rather than guessing from appearance.
Watch Which Adjustment Hole You Are Using
The buckle position provides useful information as a puppy grows.
If you gradually move through the adjustment holes as the neck becomes larger, you can see that the puppy is approaching the upper end of the collar's usable range.
Do not wait until an undersized collar becomes uncomfortably tight before considering the next size.
Collar Width Matters for Puppies Too
One reason we use different widths across our three sizes is that a collar is worn directly around the dog's neck.
Our Small collar is 3/4" wide, rather than giving a smaller dog the same 1.25-inch width used for our Large collar.
As the size increases, the width progresses from:
- 3/4" Small
- 1" Medium
- 1.25" Large
This creates different collar proportions instead of simply cutting every size from the same-width strap.
Our Leather Dog Collar Width Guide explains these dimensions in greater detail.
Buffalo Leather and the Initial Break-In Period
Our collars use 3.5 mm+ buffalo leather, so a new collar may initially feel firmer than one that has already experienced regular use.
That firmness should not be confused with incorrect sizing. A correctly sized leather collar can gradually become more flexible as the material naturally breaks in.
Avoid trying to accelerate the process by soaking, aggressively bending, stretching, or heavily oiling the collar.
Read our Leather Dog Collar Break-In Guide for the proper approach.
Plain, Basket or Floral Tooled for a Puppy?
Once the correct size has been established, style becomes a separate decision.
Our core leather collar designs include:
- Plain / Simple Border Tooled
- Basket Tooled
- Floral Tooled
All three are planned in Black, Brown, and Tan.
Tooling should not change how you size the collar. Choose the correct neck fit first, then select the design you prefer.
Compare the patterns in our Leather Dog Collar Styles Guide.
Will a Puppy Outgrow a Leather Dog Collar?
Possibly. A growing puppy may eventually exceed the usable adjustment range of its first collar.
That should be treated as normal growth rather than a failure of the collar.
Trying to avoid ever replacing a puppy collar can lead owners toward oversized or incorrectly adjusted gear. Correct current fit is more important than trying to make one collar cover every stage from puppy to adult.
What Happens When Your Puppy Reaches the Next Size?
Measure again before moving up.
For example, do not switch from Small to Medium solely because the Small collar is getting older. Move to Medium when the puppy's actual neck measurement makes the Medium fit range appropriate.
The same principle applies when moving from Medium to Large.
Does Breed Predict the Final Collar Size?
Breed can provide general expectations about adult body size, but it should not replace measurement.
Individual dogs within the same breed can develop differently, and mixed-breed puppies may be even harder to predict from appearance alone.
Use the dog in front of you, not an estimated adult breed chart, to determine the collar that fits today.
What About a Leather Leash for a Growing Puppy?
Leash sizing works differently from collar sizing.
Our collar dimensions change because the collar sits around the dog's neck. Our standard leather leash is designed around one 6 ft finished overall length and 3/4" width.
The leash therefore does not need to move from Small to Medium to Large as the puppy grows.
For the reasoning behind this approach, read our Leather Dog Leash Buying Guide.
Taking Care of a Puppy's Leather Collar
Puppies can expose collars to dirt, moisture, play, and plenty of movement. Check the leather and hardware while you are checking the fit.
Inspect:
- The buckle
- The adjustment holes
- The hand stitching
- The leather around hardware
- The collar edges
- Areas that repeatedly bend
If the collar gets wet, wipe away excess moisture and let the leather air dry naturally. Avoid concentrated high heat and excessive conditioning.
Our Leather Dog Collar Care Guide covers maintenance in detail.
Choosing Your Puppy's First Leather Collar
The process should stay simple: measure, fit, monitor, and re-measure as the puppy grows.
Do not size according to expected adult weight, intentionally buy an oversized collar, or rely on leather stretch to accommodate future growth.

Frequently Asked Questions
What size leather collar should I buy for a puppy?
Measure the puppy's current neck and compare that measurement with the collar's actual adjustment range. Do not choose solely according to breed, weight, or expected adult size.
Should I buy my puppy a collar that is too big so it can grow into it?
A collar should fit correctly during current use. Buying substantially oversized gear solely for future growth can create a poor fit now. Re-measure and move to the next size when appropriate.
How often should I check my puppy's collar?
Check the fit regularly because puppies can grow quickly. Recheck whenever you notice body growth, weight or coat changes, a different collar position, or movement toward the final adjustment holes.
Will a leather collar stretch as my puppy grows?
Leather can become more flexible through use, but stretching should not be used to accommodate puppy growth. Replace or move up in size when the dog's neck exceeds the collar's appropriate fit range.
Is buffalo leather too thick for a puppy collar?
Leather thickness is only one part of collar design. Our collars use 3.5 mm+ buffalo leather while changing the strap width according to size, with the Small collar using a narrower 3/4-inch width.
Does a puppy need a shorter leash?
Not simply because it is a puppy. Collar sizing and leash dimensions solve different problems. Our standard leash uses a 6 ft finished overall length and 3/4-inch width rather than Small, Medium, and Large leash sizes.
When should I move my puppy to the next collar size?
Re-measure the neck as the puppy grows. Move to the next size when the dog's measurement and required adjustment make that collar's fit range appropriate rather than waiting for the current collar to become too tight.
