A 'hangry' dog demands treats as he continuously hits the treat jar and bark for attention on April 12 in Calgary, Canada.

This pup, Rusty, knows exactly what he wants. According to his owner James,

"Rusty demands his cookie, whether or not he’s done anything to earn it."

James keeps the treats in a jar and when Rusty wants one he scowls and hits the jar until he gets it. Rusty knows he will always eventually get one.

"He knows he’s going to get one, but he enjoys demanding his entitlement," says James.
