wanna have a good time? you might want to consider finding a dog sitting place for climbing days.
dogs can only go where cars can go, campsites, and like 50 or 100' off the road. so not many crags in jtree meet that criteria.
not to mention, dogs in general, even good ones, don't belong at most crags shared with other people. they beg, bark, sometimes bite, step or pee on gear, etc... since it's just you, you can not watch your dog while climbing or belaying.
