The Cojack is created by crossing the purebred Pembroke
Welsh Corgi with the purebred Jack Russell Terrier. It is considered a hybrid dog, meaning it is not
purebred, however the lineage is known. Where as the term mutt is used when a dog has an
unknown lineage.
Some claim hybrid dogs are healthier, because you are
mixing up the gene pool. Many breeders of hybrids believe in what is called the heterosis effect and
hybrid vigor. Vigor means, "Physical or mental strength, force or energy."
Others disagree, claiming you are still crossing two first
generation dogs. If you breed two dogs carrying the same genetic defect, the defect will be
dominant in the dog.
Regardless, of size or lineage, all dogs are a mammal of
the Canidae family, of the order Carnivora. Canis lupus familiaris, which is a domesticated
subspecies of the wolf. Commonly referred to as a canine, dogs have instincts, which we as
humans have a responsibility to fulfill.
One of these instincts is to migrate. To fulfill this instinct
in our dog, we need to take them for a daily walk. How to walk your dog in a way
that fulfills this instinct.
