How To Cast Animal Tracks Using Dental Die/Stone

I bought some Dental Die Type IV and have been trying to cast local animal tracks. Dental Die is harder than Plaster of Paris, requires less material, and dries enough to move in about 10-15 minutes. This last part is the most important to me because my puppy is usually with me when I find them and she is not great at styaing in one spot for longer than that. I am using a 1:3 ratio of water to dental die right now, mixing in a sandwich bag.

I've tried making casts a few times during/right after rain and the dental die does eventually harden but takes 2 or 3 times longer than normal in wetter conditions like this.
