A mixed-breed dog (also called a mutt, mongrel, tyke, cur, or random-bred dog) is a dog that has characteristics of two or more types of breeds, or is a descendant of feral or pariah dog populations. The term crossbreed refers to puppies produced by the breeding technique of breeding known dogs of two different purebred dog breeds for some specific reason. The term "mutt" generally refers to a dog of unknown descent. Dogs interbreed freely, except where extreme variations in size exist, so mixed-breed dogs vary in size, shape, and color, making them hard to classify physically.
Mixed breed of dogs are called mixed breed because they have parents and ancestors that are of different breeds of dogs. These dogs are usually less expensive than dogs of one breed (Purebred dogs) and most mixed breed dogs look different from each other.
Purebred dogs have parents and ancestors that are all from the same breed of dog. The size, temperament, and appearance are the same between dogs.
Dogs that make up the Working Group were historically bred to perform specific tasks for people. This group includes sled dogs that love cold weather, living outside and need plenty of exercise. Guard dogs such as mastiffs, rottweilers and Great Danes were bred for protection and are thus alert, courageous, intelligent and independent. These dogs can be territorial and require strong leadership and structured training.
Epilepsy in dogs is one cause of seizures; dog breeds more prone include Keeshond, Tervueren, Cocker Spaniel, Poodle, Collie, German shepherd, Irish setter, Golden Retriever, Dachshund, Labrador retriever, Saint Bernard, Miniature Schnauzer, Siberian husky, and Wire-haired Terrier. What causes this "hereditary" (also known as primary) epilepsy is not known for certain. A genetic basis for primary epilepsy in dogs is possible if there is a familial history of seizures; however, a diagnosis of primary epilepsy is not proof of a genetic defect. Only DNA and breeding studies could prove that.
People select dogs on looks, size, color, coat hair. However, choosing the right dog involves selecting a pet that is compatible to your lifestyle. Not all large dogs are aggressive, not all small canines are calm. Some small breeds are great for children, others are excitable. Large dogs are excellent family companions but their size warrants adequate training to prevent damage to persons and property. The personality of a dog is fixed by genetic code from the parents. Training and environment accentuate or detract from traits, but basic personality remains.
Dogs in the sporting group are alert and naturally active with remarkable instincts in the woods or water. Many sporting dogs still participate in field activities and hunting. These loyal, intelligent dogs require a lot of exercise. Some sporting dogs are the American water spaniel, Chesapeake Bay retriever, pointer, Irish water spaniel and Labrador retriever.
Mixed breed of dogs have some advantages and disadvantages. A well bred purebred dog will be the result of a breeding between two healthy parents who have been as thoroughly screened for health problems as modern science will allow. This does offer some advantage clearly! The poorly bred purebred is much more likely to be a harbinger of various health problems common to its breed. The mixed breed, will, on average, fall somewhere in the middle. The thing to keep in mind is that you are adopting one dog, not the average of the type. So definitely, unless you are willing to risk heartache, adopting from a rescue that has at least a recent history of the dog's health, adopting an older dog (not a puppy) and definitely adopting a dog that is in good health when you adopt it are all going to up your chances of a having a healthy dog.
