an extra ticket, (out of my price range, but I'm asking nonetheless), could you?

I’d just use a Sharpie and print service dog on my golden chonk harness.
Then the questions would start sir why is your service dog trying to climb in peoples laps as they eat.

But pets, that’s what pup nights are for. Many ballparks have dog games where you can bring along if you have signed consent forms and purchased special tickets. We’ve taken dogs to 3 different ballparks including T-Mobile Park in Seattle where the picture was taken.
