Kikko has some long eye stains/tears lately. he's never really had before. he'd have his eye boogers .. hehehe

but in the past couple of days i've noticed he's had some major tears going on.
i wonder what's causing it. anybody out there have any ideas? I haven't switched his diet at all but he has bee n spending the day with my parents' yorkie more. could it possibly be the weather? it has been getting pretty hot and humid ....

i'm baffled
