You will likely find lots of "cute" Havanese sites on line, but  many may not be safe choices. Some may be "high volume breeders" (aka puppy mills) masquerading as having home-raised puppies. Others may be brokerage services. selling puppies for a variety of breeders. Often these types of sites do not stand behind their dogs, which may or may not be from genetically healthy parents. And, perhaps worst, there are scammers, who may not have puppies at all (just photos), or who have "stolen" legitimate names of parents to sell puppies of sketchy origins. Buyer Beware!  The Havanese Club of America website has educational information for puppy buyers - please check it out!
