Look, if you're going to take the dog for a walk, why not just take the dog for a walk. Pushing a bike and taking the dog for a walk is sheer lunacy.
Note the hipster bike though. White walled tyres. Fat saddle. Some kind of trendy hippy footwear. Funky light blue colour on the bike.
My disdain for bike pushing hipsters with dogs is that they take up 86% of the available path, and don't give a flying fig for those who want to get past. Some people need to have some sense beaten into them with a dead possum.
