Oh I don't know, at least you could know when they wanted a treat rather than they needed to go out to pee. The latter dictates getting up from the computer, the former would not unless you felt it appropriate. But our older dog uses the same non-verbal signals for both.
Does anyone have a dog that is even sometimes uninterested in food? (except when they're sick)
Ive often wondered just how much my two dogs would eat if given the chance to have all the food they wanted.
