Barley goes to a puppy socialization class offered by the WI humane society, and it has done wonders for his behavior around other dogs and strangers... might want to look into your county's Humane Society. The dog parks around milwaukee mostly require pups to be at least 4 months old, but they're open year-round. if you start to go, i wouldn't go the first time on a weekend day - they can be crazy busy and intimidating for the first time. Good luck!
