Heavy use of interbreeding caused problems in several breeds of dog.
No, dogs as a species have not been genetically modified. However, selective breeding over time has led to different breeds with specific characteristics.
The pit bull was originally bred for bull baiting, which was a blood sport in the 1800s, mainly in England. The sport soon became outlawed, but now in present times, even though it is illegal, dog fighting is commonly practiced in pits. People have bred pit bulls to be aggressive, and here we are blaming the pit bull.
Seeing a white ghost dog indicates that you are having luck or being protected. Legend has it that a white dog named Ghost, saved the life of his owner, Joey, when he fell into a ravine. The farmer that was led to help Joey by Ghost, commented what a great dog he was. Joey told the farmer that Ghost had died a month before.
Variations in breeding over the years. Some dogs were bred to be short and small to hunt ground hogs or badgers, others where bred to do well in the cold and run long distances such as sled dogs. By breding certain dogs with certain characteristics over time you change the make up of the animal. If humans had never interfered with natural canine breeding we would not have nearly as many breeds as we do now. A example is the new "designer" breeds such as Labordoodles or Pickadoodles or what have you.
Dogs are wolves that have been selectively bred for varying uses by humans. Different dog breeds were created for varying purposes, such as hunting, company, searching, guarding, attacking, eating (in some parts of the world), etc.

The German Spitz and AED used to be the same dog, but a couple of centuries on different continents have led to them being separate breeds.
Artificial selection of dogs has led to the creation of diverse dog breeds with specific characteristics through selective breeding practices. This has resulted in a wide range of sizes, shapes, coat types, and temperaments among different dog breeds.
Artificial selection, where humans selectively breed dogs for specific traits, has led to the wide variety of dog breeds we see today. This process has created breeds with distinct physical characteristics, behaviors, and abilities, resulting in a diverse range of dogs suited for different purposes and preferences.

Half-Breeds
They used to be a fairly uncommon breed up until recent years, which has seen a resurgence in their popularity and led to increased breeding due to demand, which means they are less common now. However, they aren't amongst the MOST common breeds of dog.
Humans have sped up evolution in dogs through selective breeding, which involves choosing specific traits to pass on to future generations. This process has led to the development of different dog breeds with desired characteristics.

Humans have used selective breeding to accelerate the evolution of dogs by choosing specific traits to breed for, such as size, coat color, and behavior, over many generations. This has led to the creation of various dog breeds with distinct characteristics.
