Guessing a mixed-breed's ancestry can be difficult even for knowledgeable dog observers, because mixed-breeds have much more genetic variation than purebreds. For example, two black mixed-breed dogs might each have recessive genes that produce a blond coat and, therefore, produce offspring looking unlike their parents.
They found that purebreds were more likely than mutts to have any of 10 different genetic conditions—everything from cataracts to dermatitis to bloat (a distended stomach condition that can be ...
In 2013, a study found that mixed breeds live on average 1.2 years longer than pure breeds. [21] John Scott and John L. Fuller performed a detailed study of purebred Cocker Spaniels, purebred Basenjis, and hybrids between them. [22] They found that hybrids ran faster than either parent, perhaps due to heterosis.
Popular large breeds like Labradors and Golden Retrievers have an average lifespan of 10 to 12 years, although as with any breed, some dogs live longer. We also rounded up a full list of dog ...
The study concluded that while Australian Cattle Dogs are a healthy breed and do live on average almost a year longer than most dogs of other breeds in the same weight class, record ages such as Bluey's or Chilla's should be regarded as uncharacteristic exceptions rather than as indicators of common exceptional longevity for the entire breed.

A new study finally answers whether mixed-breed dogs are healthier than purebreds, and now that whole question has been settled. According to new research from the Royal Veterinary College, the ...
Some health issues not common in either parent breed may be more common in the crossbreed than both of the parent breeds. Prolapsed nictitating membrane gland is a condition more common in the Puggle and Jug than both of the parent breeds, which shows the complexity of genetics and provides evidence against the theory of hybrid vigour .
A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. A domestic animal of unknown ancestry, where the breed status of only one parent or grandparent is known, may also be called a crossbreed though the term "mixed breed" is technically more accurate.
