Adult Labrador and owner with a reminder to check the dog before choosing an antler size.

Antler Size Guide for Dogs: Weight, Fit and Cut

Start with the current weight range, then check the individual dog's mouth fit and dental suitability. Heartland has five sizes in whole deer, whole elk and split elk. A weight chart helps compare products. It cannot establish that a hard chew is safe for a particular dog.

Heartland antler sizes and pack counts

Size Catalog dog-weight range Pieces per pack Compare products
Small 5-25 lb 2 Small antler chews
Medium 25-45 lb 1 Medium antler chews
Large 45-65 lb 1 Large antler chews
Extra Large 65-85 lb 1 Extra Large antler chews
Giant 85+ lb 1 Giant antler chews

These are the store's current catalog ranges, checked September 12, 2026. Boundaries overlap. At a boundary, compare the actual piece dimensions and mouth fit instead of rounding the dog's weight to force a choice. Natural pieces vary in shape. Read the specific product description, and ask us for product details when the listed measurements do not answer your question.

Heartland antler sizes: Small 5–25 lb, Medium 25–45 lb, Large 45–65 lb, XL 65–85 lb and Giant 85+ lb.
Catalog weight ranges are a starting point. Dog illustrations do not establish individual fit.

Check suitability before size

Heartland does not recommend antlers for puppies with developing teeth, senior dogs with worn teeth, dogs with existing dental damage or a prior tooth fracture, or dogs that bite down forcefully with their back teeth. Discuss hard chews with your veterinarian. Our safety guide explains the risk and source guidance.

Compare the piece with the dog's mouth

  • Choose a piece too large to fit fully inside the mouth.
  • Check length, width and shape, rather than the size name alone.
  • Check the piece again as it wears. The original label no longer describes its current size.
  • End use if the dog crushes the piece, swallows material, or shows discomfort. A larger piece is not a remedy for these behaviors.
Check antler length, width and actual mouth fit.
Check dimensions and mouth fit separately from the weight range.

Choose the cut with clear limits

A split elk antler exposes the inner surface along its length. A whole antler retains the outer surface around it. Both retain hard antler material. Neither a split cut nor a larger size removes tooth-fracture risk. Compare split and whole cuts after the suitability check.

Compare pieces per pack

Small whole deer, whole elk and split elk packs each contain two pieces. Medium, Large, Extra Large and Giant each contain one. Compare the size and piece count when comparing prices.

Small Heartland antler packs contain two pieces; other catalog sizes contain one.
Small packs contain two pieces. Medium through Giant contain one. Product illustrations show the count.

Stop and replace by condition

Supervise every session. Remove a piece that can fit fully in the mouth, has cracks or sharp edges, or sheds pieces the dog swallows. Contact your vet about mouth pain or damage. Use the replacement guide to record wear without relying on a fixed lifespan.

Inspect antlers as they wear and remove pieces that are too small, cracked or sharp.
Remove damaged or swallowable pieces. Recheck condition before each use.

Frequently asked questions

Does breed determine the correct antler size?

Breed alone cannot establish mouth fit, chewing behavior or dental suitability. Use current weight and actual piece dimensions, and discuss hard chews with your veterinarian.

Should I size up for a dog that crushes antlers?

Stop use if the dog crushes the antler or swallows pieces. Choosing a larger antler does not remove the risk from forceful biting.

How many antlers are in each Heartland pack?

The Small whole deer, whole elk and split elk products each contain two pieces. Medium, Large, Extra Large and Giant each contain one piece.
