Stop the antler if your dog develops diarrhea after chewing it. The timing is useful information, but it cannot prove the cause. Do not assume that marrow, a short introduction period or a different antler grade explains the problem.
What could be involved?
Diet changes, infection, parasites and swallowed objects are among the possible causes of diarrhea. Cornell's veterinary diarrhea guide explains why the dog's other symptoms and medical history matter. A claim that a three-day chew routine prevents most diarrhea needs evidence that is not available here.

When to contact a vet
Contact your vet promptly if diarrhea comes with vomiting, poor appetite, lethargy, blood or black stool. Seek care if it persists or returns. A puppy, older dog or dog with existing illness may need help sooner. If any antler piece may have been swallowed, call now and read our swallowed-piece guidance.
Keep fresh water available. Ask the vet about feeding and treatment. Do not give human anti-diarrhea medicine unless directed by a veterinarian.

Useful details to record
- When the chew session and symptoms started.
- Other foods, treats or new medicines.
- The product, cut and size used.
- Whether a chunk is missing.
- Changes in appetite, energy, vomiting and stool.
A photo of the chew and the packaging can help identify the product. The clinic may ask for a stool sample. Follow its instructions.

Should you try a different antler?
Wait for veterinary advice before restarting. Switching from split to whole, buying a higher grade or shortening sessions does not establish that the underlying problem has been resolved. Antlers also have a separate tooth-fracture risk.
For product identification or an order concern, contact our team. Medical assessment belongs with the vet who can examine your dog.

Frequently asked questions
Can antler chewing cause loose stool?
Loose stool can occur after chewing, but timing alone does not establish the cause. Stop the chew and ask your vet about persistent symptoms, warning signs or any swallowed piece.
Does a three-day introduction prevent diarrhea?
This guide has no clinical evidence that such a routine prevents diarrhea. Do not restart a chew to test that claim while your dog is unwell.
Should I switch from split to whole antler?
A different cut does not diagnose or treat diarrhea. Ask your veterinarian before restarting antlers.
