What this record means
The record shows that “MONTANA ANTLERS” is an abandoned application, filed by Justin Davidson, a Georgia corporation, and it never reached registration; the last status event was an abandonment notice on August 8 2016 after the applicant failed to respond to a final refusal. The only goods listed are dog treats, edible chews for dogs and edible organic pet treats for dogs, all in International Class 031, so a similar name used for pet food or treats would be the closest area of concern, while uses in unrelated categories would be farther from the scope shown here. The record does not give the owner control over every use of the words “Montana” or “Antlers” in any context. The prosecution history reflects a final refusal in December 2015 followed by an abandonment in August 2016, but there is no indication of any opposition, cancellation proceeding, or other enforcement activity. I'd treat this as a moderate concern if you plan a pet‑treat brand with a similar name, because the abandoned filing still signals that the USPTO found a conflict in that product area.
