I do bring my dog at certain courses where its not crowed with players or non-players.
I mostly bring him to
Chili course until he got too old to walk the whole 18 hole course. He's 13 years old now. He has been going that course since he was an year old.
In his younger dog year, he tend to hang out with me and likes to meet other dogs at the course. Of course, I had to make sure that the dogs can get along well before moving on. Other dog owners or players don't mind to allow my dog to approach them to say "hi" and sniff them up before coming back to me to the next tee. His only skill of disc golfing is to able to get in the water and pull out the disc for me after I pointed him to the right spot. He also have a good common sense of where to dump his poops. He tend to go so far off the course into the thick unplayable area and take the dump there. I was never able to find his poop but I always carry plastic bags and leash anyway.
Hope someday for my next dog, I plan to train him or her to be DG caddy that can carry my stuff, seek out and retrieve lost discs from the water, tall grasses or under leaves. Whatever.
Maybe getting Bloodhound dog will do that...umm...
