I had 2 run-ins with wild pack dogs. 1 time I was dove hunting and had taken a break and cleaned my birds. The dogs came through the field and were walking 30 feet to my side and didn't see me through a tree break. They went down and ate the dove remains that I'd discarded and turned around and walked right past me again. 2 BIG pits, 1 rottie, and a mix. All looked pretty haggard. The 2nd time, I was driving through my neighborhood and saw a 3 pack of mix dogs. I'll always stop and see if they're friendly enough to check for tags. The leader of the pack slowly walked towards me with it's hair raised, head down, and teeth "grinnin". He looked "unhappy" so I hopped back in the truck and told the wife "nope... they don't want anything to do with me". They sure do seem to switch over to a wild pack mentality when they run the streets. Pretty cool to see them work but nothing I want to get involved with.
