We took the dogs with us when we went to go walk around the park. Honestly I thought it made sense. There have been stories of people getting robbed because they are playing the game. If I have my dogs with me even if I don't see the person approaching, my dogs will. And who wants to rob a person that has 2 large dogs.
I mean one of the biggest issues I saw was that you have to pay attention to your dog as well, which can get difficult. I tried to have Forbes sit every time I stopped to catch something. It was pretty difficult because there were so many people around. Honestly it depends on the dog.
