OCD

It's funny to think about pugs having personality disorders.  I mean, they are dogs right?  They eat, sleep, fetch, eat and sleep some more. But Indy the pug has the ability to spot a morsel of food from 50 yards away.  What happens next is puffing, snorting, and growling, which leads to full on barking.  Not regular barking either.  It is a bark that instinctively says "Listen to me, I NEED that piece of food, or else"!  This bad habit has continually gotten worse.  He is the sweetest dog 22 hours of the day, the other 2 seem to sometimes cancel out all his nobleness.
