I have 2 greyhounds.

This place is very dog friendly (treats and water provided). the food was good but I went to dinner on a Saturday night at 7 and they were out of several things. Food came out before appetizers too. But once the food came it was AMAZING. Great BBQ. Order the fried green beans from the appetizer menu.
this park is absolutely astonishing beautiful. Dogs are welcome in the park overall but not in any of the walking trails.
They have the visitors center closed (COVID and 2020 can suck it) but in the visitor center area they have water for the dogs.
if you’re planning on hiking, someone will have to stay with dogs in parking areas.

we went here for dinner with all my kids (2 two-legged, and 2 four-legged) and the staff was extremely accommodating and friendly. Go! (and have the pineapple curry). :-)
