We will be visiting the museum In October and I would like to know if the museum is dog friendly. She is small dog and she will be in a dog stroller. I am a dog owner that picks up after her dog.

Hi Kathleen -- Dogs are welcome on the grounds of the Museum (look for designated relief areas). Service dogs and military, state and federal working dogs are allowed inside the Museum. Please see our Plan Your Visit page for more information: https://www.usmcmuseum.com/plan-your-visit.html.

In special Areas dog's are prohibited but not everywhere

Not sure, question websites.

They have a special exhibit four dogs in the service. I would hope they would be open to your request.

I don't think they are unless it's a guide dog honestly but I am not 100%.
