Welcome to Windfall Havanese

Welcome to Windfall Havanese


Windfall Havanese is located just outside of Chicago, IL and about half an hour west of O’Hare International Airport. Windfall has been a family affair since our start in 2005 when we acquired our very first show dog, and has developed from a weekend hobby into a passion that is shared by the entire family.

Diane Sako has been employed in the mortgage industry for 20 years and is currently the Underwriting Manager/Director of Quality Assurance with DE/SAR designation for a local mortgage company. She works from home a majority of the time which gives her ample opportunity to spend with the dogs and puppies. Diane is responsible for all paperwork and is in charge of keeping track of vet records, health testing, show entries, etc as well as planning all of the litters for the year and is primarily responsible for the whelping, socialization and placement of puppies that are produced by our breeding program. Diane is the one to contact for questions regarding current or upcoming litters, puppy availability, pedigrees, health testing, and stud inquiries.


Karen Sako is employed as a freelance graphic designer and is also a fine arts teacher at Main Street Art Center in Lake Zurich, IL. She has been teaching children of all ages courses in drawing and painting, and is also an artist herself, specializing in oils and mixed media. Karen is the primary handler for Windfall and is responsible for the training, grooming and ring presentation of all our current and up and coming show dogs. She has finished a majority of our havanese and has done a phenomenal job with them in the ring. Her accomplishments include multiple Toy Group 1’s and a Best In Specialty win over some of the top dogs in the nation. Karen is also involved in the whelping and raising of our puppies and is the person to go to for grooming and training hints and advice.


We would also like to take a moment and thank a few very special people who helped us on our way. First, to Cheryl Filson from Cher Chien Maltese for taking us under her wing and starting us out on the right path. To our cousin Rose Benanti, who handled our very first show dog and has always been there to support us through the years. To John Benoit from Dakota Showdogs, who has been a friend and mentor to us and taught us that the show world is not just about winning a ribbon, it is about the friendships you make and the laughs and good times that you share, and to never take ourselves too seriously. And finally to our parents, Bill and Judy Sako. They have been there for us through thick and thin, good and bad, and have served as unpaid transportation coordinator, puppy sitter, and have always given us their 100% unconditional support…and especially to mom for spoiling all the dogs rotten. To them and to everyone else who has helped guide us on our adventure…a huge THANK YOU!!! We could not have done it without you!
