A pointless relationship
Dogs can be friendly to a fault. They’ll jump, run at high speed, and pounce on you out of sheer joy when you get back from work. This pupper, however, had feline-level curiosity when it encountered a porcupine in the wild. Barkley was trying to make a new friend, but the porcupine had another idea in mind.
Just look at the sad expression on Barkley’s face, wondering how his new friend could treat him so badly. Wait a minute. Barkley the dog? Ha, nice! Because dogs bark! Sadly, Barkley was barking up the wrong tree while trying to befriend Sonic.
