For as long as there has been mutual aid between humans and dogs, it is safe to say that dogs are man's best friend.
Breeding programs and inquisitive breeders have resulted in a wide range of dog sizes, shapes, colors, and coat kinds.
Recently popular mixed-breed puppies in the 2000s and 1990s include the Pomsky (Pomeranian and husky) and the goldendoodle (golden retriever and poodle).
But there's a hidden cost to the health of dogs when they're mixed and bred all the time.
When these canines, who were originally used for tactical hunting,
became show dogs, their owners began shelling out thousands of dollars to keep them healthy.
As a result of their bodies' inability to cope, some dogs suffering from these conditions have a reduced lifetime.
