Short answer: Match the antler to your dog's weight and jaw, not to what looks impressive. Small antlers suit dogs around 10 to 20 lbs, medium suits 20 to 50 lbs, and large suits 50 lbs and up. When a dog sits between two sizes, size up — an antler that's too big is a minor annoyance, while one that's too small is a choking risk.
Why size is the decision that matters most
Most antler problems trace back to the wrong size rather than the wrong antler. A chew that's too small can be swallowed whole or wedged between the back molars. One that's far too large frustrates a small dog into giving up. Getting size right the first time is most of the job.
The rule of thumb: the antler should be longer than the width of your dog's lower jaw, and thick enough that it can't slip sideways behind the molars.
Small dogs, roughly 10 to 20 lbs
- Start with a split antler. The exposed marrow gives a small dog an immediate reason to keep going, instead of gnawing at a hard outer wall and losing interest.
- Two-packs are the better value if your dog already likes antlers, since you have a spare when the first wears down.
- Retire it early. Small dogs reach the "small enough to swallow" stage faster than you'd expect.

Medium dogs, roughly 20 to 50 lbs
- This is where you get a real choice. Medium dogs handle both split and whole, so pick based on chewing style rather than size alone.
- Split for enthusiasm, whole for longevity. A split antler gets used faster; a whole one lasts noticeably longer.
- Whole antlers suit dogs who pace themselves and chew in sessions rather than attacking a chew until it's gone.

Large dogs, 50 lbs and up
- Go whole and go large. Big dogs work through split antlers quickly, and the denser whole antler is what makes the chew last.
- Length matters as much as thickness. A long antler gives a large dog something to brace against with their paws.
- Split large antlers still have a place for older large dogs or gentler chewers who want easier access to the marrow.

What to look for beyond size
- Naturally shed, not harvested. Elk drop their antlers every year, so a shed antler means no animal was harmed.
- Grade A only. Older antlers that have weathered on the ground go chalky and brittle. Fresh sheds stay dense.
- No chemical cleaning or sticker residue. Hand-processed antlers skip the bleaching some cheaper imports go through.
- Odor-free and mess-free. Unlike bully sticks, antlers don't go greasy or smell on the carpet.
- Naturally occurring minerals including calcium, phosphorus, and zinc.
Chewing safely, whatever the size
Antlers are among the hardest chews available, and that hardness is the trade-off for how long they last. Supervise chewing, cap sessions at around 30 minutes rather than leaving an antler down all day, and retire any antler once it's worn small enough to swallow.
Use the thumbnail test: if you can't dent it slightly with your nail, let a determined chewer work at it gradually rather than at full force. Puppies, senior dogs, and any dog with a cracked or worn tooth or existing dental disease should check with a vet before starting antlers — a softer chew is often the better call for them.
Frequently asked questions
What size antler should I get for my dog?
Match it to weight: small for roughly 10 to 20 lbs, medium for 20 to 50 lbs, large for 50 lbs and over. The antler should be longer than the width of your dog's lower jaw. If your dog falls between sizes, size up.
Can I give a large antler to a small dog?
Yes, and it's safer than the reverse. A too-large antler is harder for a small dog to make progress on, but it removes the choking and molar-wedging risk entirely.
How long does an antler chew last?
Anywhere from a couple of weeks to a few months, depending on your dog's size, chewing strength, and how often they get it. Whole antlers last considerably longer than split.
When should I throw an antler away?
Once it's worn down small enough that your dog could swallow it, or if it develops a sharp edge or cracks. Replace it rather than waiting.
