That paper may matter a lot more than you think. When buying a puppy in Canada, the word “purebred” is reserved for dogs of pure ancestry that are registered with an approved dog registry. For the Havanese, this is the Canadian Kennel Club. Furthermore, the Canadian Animal Pedigree Act states quite clearly that “a buyer of an animal represented as purebred is entitled to its registration certificate”. It is against the Canadian Livestock Act to sell a purebred dog without the papers therefore doing so is an illegal act and the persons that do this could be asking for problems if they are caught.
If you have no registration, and the unethical breeder you get your puppy from has more than one breed, you may not be getting what you think you are. Even at a perceived discounted price for an unregistered puppy, you could be paying a huge amount for a crossbred or mixed breed and not a Havanese at all. DNA testing is available, and many of the reputable breeders have their stud dogs DNA profiled so if there is ever any question, parentage can be positively established. This is unlikley to happen with an unethical breeder. In their eyes, you wanted a puppy and you got a puppy. End of story.
Under the "Animal Pedigree Act" ( 1985, c. 8 (4th Supp.) ), any dog sold as a purebred animal in Canada MUST be registered with an acceptable registry. In the case of the Havanese, this registry is the CKC, Canadian Kennel Club. Paperwork from the CKC is completed and signed by the seller and buyer at the time of sale and the Certificate of Registration from the CKC must be supplied to the buyer within 6 months of purchase of the puppy. This is a requirement under Canadian Federal Law. As well, any responsible breeder should be a member of the CKC and these requirements are also included in the club's Code of Ethics along with a requirement to provide this paperwork at no additional cost to the buyer of this dog/puppy.
