The size of Hilton's puppies may also be cause for concern, as breeding such tiny dogs may not always be in the animals' best interests. Canine researcher Mia Cobb spoke to The Dodo about some of the health problems commonly seen in dogs who are bred purely for size, including seizures, jaws that are too small for all the teeth to fit in and spinal issues.
"This is because they are bred for to meet a fashion ideal purely based on looks, often exaggerating their puppy features, rather than for sound health, good behavior and longevity," Cobb said. "Many of these issues may not be immediately apparent to a new puppy owner, but develop or deteriorate over the first year of life."
Hilton's new puppy may be happy and healthy. But remember that there are thousands of dogs of all shapes and sizes waiting in shelters for a loving family. If you are ready to provide a forever home for a pet, skip the pet store and check out Petfinder or your local ASPCA to get to know the rescues waiting for love.
