The Miniature Pinscher

The Miniature Pinscher, also known as the Min Pin by fanciers, is a toy breed of dog. Miniature Pinschers were first bred to hunt vermin, especially rats. In its native Germany, the dog is known as the Zwergpinscher. Pinscher is the German word for biter and Zwerg means Dwarf in German. The Miniature Pinscher is also known as the "King of the Toy Dogs". Though the Miniature Pinscher is considered a toy breed, it is in fact one of the oldest of the terrier breeds.
  • Although the breed is not necessarily bad with children, much care must be taken in educating youths about proper handling and play. Although relatively sturdy for their size, they can be easily injured by rough play with a child. In addition, their high-strung temperament leaves little patience for such rough play.
  • Grooming is easy, as the smooth, short-haired coat requires little attention. Care must be taken in colder weather as the coat provides virtually no insulation from the cold.
  • Due to their instinct to hunt vermin, special care must be taken in preventing a Miniature Pinscher from "attacking" small objects, such as bottle caps, as they could pose a choking hazard.
  • Miniature Pinschers are also prone to overeating and should have their diets monitored to prevent obesity.
  • This breed has an insatiable curiosity, so the best toys for Miniature Pinschers are ones that stimulate their curiosity. This may include toys that move or make an interesting noise. Miniature Pinschers enjoy having a collection of such toys, which they will hoard and spend much time in moving from one collecting place to another.
  • Miniature Pinschers are territorial, so they should be provided with their own place to rest and sleep, though they will commonly stake a claim to a particular piece of furniture or curtain under or behind which they will sleep when people are in the room. They prefer to sleep on soft objects as well as under soft objects, so a small blanket should be provided to cover them. Unless the owner is amenable to sharing his or her bed, bedroom doors must be kept closed at night as Miniature Pinschers will jump onto beds and crawl under the covers. Care should be taken not to accidentally injure a Miniature Pinscher while they are sleeping under blankets.
It is essential due to the energy level of this breed that a secured fenced yard be provided. Miniature Pinschers need to exercise regularly. In addition, due to the nature of this breed, when in public this breed must be kept on harness and leash. It is natural for this breed to bolt if something of interest catches its eye. It is better to use a harness as a collar can hurt the dog's neck when he or she bolts.

Cruise control

Cruise control is a system that automatically controls the rate of motion of a motor vehicle. The driver sets the speed and the system will take over the throttle of the car to maintain the same speed.

Advantages and Disadvantages
Cruise control has many advantages but also some serious vices. Some of those advantages include:
  • Its usefulness for long drives across sparsely populated roads. This usually results in better fuel efficiency.
  • Some drivers use it to avoid unconsciously violating speed limits. A driver who otherwise tends to unconsciously increase speed over the course of a highway journey may avoid a speeding ticket. Such drivers should note, however, that a cruise control may go over its setting on a downhill which is steep enough to accelerate with an idling engine.
However, cruise control can also lead to accidents due to several factors, such as:
  • The lack of need to maintain constant pedal pressure, which can help lead to accidents caused by highway hypnosis or incapacitated drivers; future systems may include a dead man's switch to avoid this.
  • When used during inclement weather or while driving on wet or snow- and/or ice-covered roads, the vehicle not equipped with Electronic Stability Control could go into a skid. Stepping on the brake such as to disengage the cruise control often results in the driver losing control of the vehicle.
Driving over "rolling" terrain, with gentle up and down portions, can usually be done more economically by a skilled driver viewing the approaching terrain, by maintaining a relatively constant throttle position and allowing the vehicle to accelerate on the downgrades and decelerate on upgrades, while reducing power when cresting a rise and adding a bit before an upgrade is reached. Cruise control will tend to over throttle on the upgrades and retard on the downgrades, wasting the energy storage capabilities available from the inertia of the vehicle. The inefficiencies from cruise control can be even greater relative to skilled driving in hybrid vehicles. Many countries establish that it is illegal to drive within city limits with the cruise control feature activated.
