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.
The confusing thing for many people is that FWD cars are actually One wheel drive. AWD, 4x4, and Limited Slip Differential (LSD) vehicles are Two-Wheel drive. Locking 4x4s are three or 4 wheel drive. Today, many people believe AWD and 4x4 mean the same thing. However, this is very wrong.
