Is this pet friendly?

Yes even ride horse's here

Depending on pet size if it's a bigger dog that likes to walk you maybe you can find an easier trail to walk on first for the rough path ways in and out up and down hills it wouldn't be the easiest thing but there's nothing saying you aren't aloud to do it

Not unusual to see dogs on these hikes! Some places are a little more difficult than others.

As Emily said. The trail is pet friendly is they are up for the hike.

If they can do the walking yes
