i'm sure the germ thing is correct, but the big difference is that humans generally don't eat POO or lick up PEE or VOMIT and whatnot. it's not the germs that grosses me out when i see a dog happily cleaning it's owers face, it's the fact that just recently that tongue was covered in faeces.
oh and i've never seen a human poo or pee in dolores park, but i know it happens
sorry about the weird post... i saw a comment you made somewhere about dogs and i just got so excited... i have two dogs right now both rescues one from a scary back yard, one from a shelter... what i meant by rescue though is that my boyfriend and i find wanderers ALL the time in our town... i think people just let them out to roam, or lose track, or go on vacation without making plans... and we take them where ever we can... their homes... or ours...
