Call your veterinarian now if your dog swallowed an antler piece, even if the dog seems well. Remove the remaining chew. The clinic can decide whether your dog needs examination, imaging or a specific monitoring plan. Do not wait for a guessed passage time.
When to seek emergency help
Go to an emergency veterinary clinic if your dog has trouble breathing, collapses, has pale or blue gums, repeatedly retches, or has a swollen or painful abdomen. Call the clinic while arranging transport if you can do so safely. Cornell lists these among emergency warning signs.

What to tell the vet
- Your dog's weight, age and relevant medical history.
- When the piece was swallowed.
- The estimated size and shape of the missing piece.
- Whether it looked sharp, cracked or rounded.
- Any vomiting, appetite change, pain or change in stool.
Keep the remaining antler or take a photo for the clinic. Avoid handling the dog's mouth if the dog is distressed or may bite.

Why looking well does not settle the question
Some swallowed objects pass; others cause a dangerous obstruction. The VCA veterinary guide to swallowed foreign bodies explains that assessment depends on the object and the animal. A dog's weight or a smooth-looking fragment does not prove passage will be safe.
Do not induce vomiting or give medicines, oil, bread or another home remedy unless your vet directs it. Follow the clinic's instructions on food, water and observation. A web article cannot determine the piece's location.

After the immediate problem
Ask the vet whether this dog should have antlers again. Replacing a swallowed piece with a larger or harder antler is not an automatic solution. Keep the product details so the clinic and seller can identify what was used.
Review our hard-chew precautions and puppy guidance. For a product concern, contact Heartland Antlers. The store contact is not an emergency veterinary service.

Frequently asked questions
My dog seems fine after swallowing antler. Should I call?
Yes. Call your vet now and describe the piece and your dog. A normal appearance does not establish that the piece will pass safely.
Should I make my dog vomit?
Do not induce vomiting unless your veterinarian directs it for this specific incident.
How long does an antler piece take to pass?
There is no safe universal waiting time. Your veterinarian must decide whether examination or monitoring is appropriate.
