The Chilier brings the Chihuahua together with the playful Cavalier King Charles Spaniel.


The Chilier is a more recent addition to the roster of Designer Dogs in the U.S. Typically these dogs are first generation offspring of two different purebred dogs – in this instance the Chihuahua and the Cavalier King Charles Spaniel. Though the Chilier is a newer designer dog, his ancestry dates as far back as Pre-Columbian Cavalier King Charles Spaniel was a favorite of royalty.


The Chilier is not a purebred and therefore is not registered with the American Kennel Club (AKC). Both parent lines are members; the Chihuahua joined the AKC’s “toy” group back in 1904 while the Cavalier King Charles Spaniel became a member in 1995 in the “toy” group.

The Chilier’s long and silky coat requires low to moderate maintenance and sheds minimally so this dog is ideal for those not wanting to have to vacuum each day. He will need brushing 2 to 3 times per week and bathing only as needed to avoid drying out his skin. His floppy ears mean he will need to have them inspected and wiped out weekly to avoid a buildup of debris and potential infection.


Socialize your Chilier puppy early. Chihuahua DNA can result in a territorial little pooch that doesn’t play well with kids and other animals so work with him from the very beginning. Because of his tendency to joint issues later in life, don’t over-exert him with exercise that can damage bones. As with any puppy, proper nutrition is important and your vet can guide you to the best brand for this breed.
