How do you handle dogs running up to your dog when your out walking

[finn's mom]

At the dog park in Myrtle Beach, when Finn first showed signs of aggression towards unaltered males, I had to put him on his leash. I mostly just watched around us, and, would take him away from the group when dogs would come up. But, there were a couple of times, I just pulled him up and onto my shoulders, that's how Judy got that photo of him on my back in the Myrtle Beach meeting thread, there was a pit bull that wasn't friendly running up to us. Finn's not light, but, I can still get him up pretty quickly.
