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.
This has to do with the drivetrain of the car. In simpler terms, the power delivery system of the car. A 2wd or a two wheel drive is any general stick shift(manual transmission) car you drive. Either the front two rotates and pull your car or the back two rotates and push your car forward. For a 4wd or a four wheel drive, you can switch to all of the wheels being driven. Provides better grip on the road.
