I've just spent an hour with a dozen people and their co mingled 24+ dogs at the Alameda Little Dog Park, no dog exceeding 30 pounds and most well under that, including a tiny pomerainian puppy (that could be weighed in ounces) who romped and tumbled with the whole pack of dogs much larger than her and then took up residence under my chair and barked threats at a few other mutts from the safety of my knees.
Absolute delicious joy & maddness. It was wild spectator fun.
Furthermore, conversation with complete strangers came perfectly easy where mutual doggage is concerned. How lovely.
