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.

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.

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.

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.

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.
