suicidal dog 

A canine that has a look on his face of utter despair. Each time you look a suicidal dog in the eyes it makes you wonder if the dog's ever going to try to commit suicide.

Duder 1: "What the hell is wrong with your beagle dude? He looks like he wants to kill himself."

Duder 2: "I know man, he always looks like that."

Duder 1: "You got yourself a suicidal dog for sure. Make sure you don't give him any rope to play with."
