Inside the actual dig shelter, they cannot go in unless they are a service dog. However, dogs are welcome to walk along the trails and everywhere else. If you do take a tour and have the dog with you, someone or at least one person in your group has to stay with the pet outside. You and your group members can swap places so everyone still will be able to see the sub-fossils. Hope this helps.
There are nature trails, but I doubt they would be allowed in the exhibit hall. They don't allow food or drink inside, so I would not think pets are allowed.
