Once you have determined that the deer is dead, the next thing you need to do is notch your transport tag! You must immediately notch the tag (cutting out the date and the month) and then attach the tag to the animal. It only takes 60 seconds to notch the tag and attach it to the animal. Be sure to carry some strong string so that you can affix the tag.
After the tag has been notched and attached to the animal, you can field dress your deer. If you have never field dressed an animal, be sure to hunt with an experienced person who can help you. It is not difficult to field dress an animal, but it helps if you have an experienced person show you what to do.
The image is an example of a properly notched tag. Note that the entire month and date are notched. A slit through the month and/or date is unlawful.
