Pedigree or Non-Pedigree
Crossbred dogs are usually not
expensive to buy, which is an obvious advantage. They have their own
"mutt" charm, and their apparent type may be just what you are looking
for. But remember the tiny puppy may become an enormous adult. The best
way to judge is to see both parents, but in the nature of things the
father is likely to be absent when the puppies are ready to leave.
It is not necessarily true that crossbred
dogs are healthier than purebreds, as many people believe. Every
veterinarian can tell you of crossbreds or mongrels suffering from
recognizable, inherited diseases.
The advantage of picking a purebred dog is
that you know what your are getting. From a reputable breeder a Yorkshire
Terrier puppy will grow up into a Yorkshire Terrier dog, of a size and
weight that is within the breed norm, and with potential behavior
characteristics typical of the breed. There is, or should be, advice
available to deal with whatever problems may arise as a particular feature
of the breed.
There is no doubt that many breeds have
inherited problems associated with that breed, although these have often
been exaggerated in the press. It is up to the potential owner to enquire
about these problems, and to take independent advice on their
significance. It is worth bearing in mind that no species of animal,
including human beings, is free from inheritable disease. Dogs may be less
afflicted than most.
