DOGGYWOOD PITBULL KENNELS
RESPONSIBLE BREEDERS
Commit Yourself to the Puppies for Life
As a breeder, you will be gratified by phone calls and letters describing your puppies' first teeth, birthday parties, and other milestones. You'll be thrilled to receive photos of a puppy's first show win, or portraits with the puppy right in the middle of a happy family. But you will also have to be ready for bad news: a perfect family splitting up and leaving the dog homeless; a vet contacting you about an unforeseen hereditary illness; a dog you thought would be a great obedience prospect biting a young child.
As a breeder, you have to be there with advice and support for all of these situations. You must answer questions, provide resources, and assist with any problem. You must be willing to take back any dog you have bred, at any point in its life, for any reason. You must have a commitment to the puppies you brought into the world for the whole of their lives.
Responsible breeders never turn their backs on the dogs they have bred. Ensuring each puppy's quality of life is their main concern, from the moment they decide to breed to the day the puppy dies - ideally of old age, after a long, happy, fulfilling life.
Breed to Improve
Responsible breeders do not breed unless they are convinced that their knowledge, experience, and devotion to their favorite breed will result in a mating that will produce an exceptional litter of puppies, with qualities that are as near as possible to the ideal for that breed. They breed to preserve and to enhance the characteristics that make their breed unique. In short, they breed to improve.
Every dog is the best dog in the world to its owner. Responsible breeders, however, know to avoid "kennel blindness"-- in other words, they take a step back and honestly evaluate the good and bad points of their own dogs before making the decision to breed them. The goal of breeding, after all, is to produce a better dog.
Examine your dog carefully. Recognize its flaws. If you decide to continue with the breeding process, look for a mate that will eliminate or balance those flaws. The National Parent Club for your breed may also provide assistance.
The best way to get an objective opinion of your dog is to test it against others. Enter dog shows to determine how your dog measures up against the best specimens of its breeds. If you want to breed a great obedience dog or a great hunter, enter obedience trials or hunting tests. If your dog is a success at these events, you will be more confident that breeding it will make a contribution to the breed.
Know Your Genetics
A good breeder will have a basic understanding of the science of genetics. Everything about your prospective puppies-health, soundness, looks, temperament-will be determined by the genes passed on by their parents, and by their parents before them. Therefore, the selection of a mating pair should not be made on the basis of the dog's or bitch's looks (or temperament, or soundness, and so forth) alone, but should be based on an understanding of how the animal's genes contributed to its looks, and of how those genes are passed on and expressed. That is why it is essential to study the pedigrees of your mating pair. The more knowledge you have as you make your selection, the more likely you are to produce a litter with the qualities you desire.
You must also be well-versed in the genetic problems that affect your breed. Genetic defects can occur in any breed and can affect any system in the body. Some genetic diseases may occur in many breeds, others occur in only one or a few breeds. The following is a brief explanation of how genetic defects may be inherited and expressed.
Diseases that follow a dominant pattern of inheritance need only one abnormal gene. That is, if only one parent is affected, the condition will show up in each successive generation. Some individuals may be only mildly affected with the condition, making it difficult to detect. In such cases, the condition can mistakenly be thought to skip generations.
Diseases that follow a recessive pattern of inheritance occur in homozygous individuals, meaning dogs with two abnormal genes. Dogs with one mutant and one normal gene are heterozygous, and they are carriers of the condition. They appear normal but can pass the abnormal gene to their offspring. Recessive mutant genes can be passed through many generations before emerging in the offspring of two dogs that carry the same genetic mutation.
Polygenic disorders result from the cumulative action of a number of different genes. The exact number of genes involved and their individual functions are difficult to determine, and the pattern of inheritance tends to vary from family to family. Polygenic inheritance can sometimes mimic either dominant or recessive inheritance, and this feature may lead to erroneous conclusions regarding the type of underlying genetic abnormality.
Chromosomal anomalies -- defects in chromosome number and structure-can also cause genetic diseases. Dogs normally have 39 pairs of chromosomes on which genes are located. Major abnormalities in chromosome number and structure can produce serious defects.
Whether you inbreed, linebreed, or outcross may have an effect on the incidence of genetic disease in the offspring. Inbreeding is the mating of two individuals that are related through one or more common ancestors. The closest form of inbreeding involves parent-child and brother-sister matings. Linebreeding, a form of inbreeding, usually involves mating more distantly related dogs. The rate of polygenic and recessively inherited diseases tends to increase with inbreeding, because the chance that the two animals carry the same mutation is greater when the dogs are related. Outcrossing is the mating of two dogs of the same breed that are otherwise virtually unrelated.
