Are dogs aloud here?

Definitely, they often prefer dogs to people. ;-)

We camped with our dog, but she does stay in the camper when we are gone.

Depends on the dog. Some can be very loud while some are quiet. Either way, your dog will be welcomed at Riverside Campground as they welcome both loud and quiet dogs.

I don't believe in the restaurant but on the grounds definitely. I'm sure service dogs are allowed everywhere though

Yes
