The backyard dog is fast becoming a thing of the past. Decades ago, it was common for dogs to live their entire lives outside in suburban and urban yards. But as our knowledge of canines has evolved, we've learned that staying outside 24/7 can be hazardous for a dog's health.ecades ago, it was common for dogs to live their entire lives outside in suburban and urban yards.

Rear-wheel drive (RWD) typically places the engine in the front of the vehicle and the driven wheels are located at the rear, a configuration known as front-engine, rear-wheel drive layout (FR layout). The front mid-engine, rear mid-engine and rear engine layouts are also used.
Most passenger vehicles on the road today use front-wheel drive (FWD), where the engineâs power is routed to the front wheels. In fact, all but a handful of SUVs are primarily front-wheel drive vehicles, with additional components that send some power to the rear wheels as the need arises. Front-wheel drive designs are cheaper to manufacture and more space-efficient than rear-drive systems.
