The term backyard breeder
refers to people who breed dogs, but are ignorant of
things such as, Breed Standard for the breed in
which they are breeding, Genetic Traits and faults
to that specific Breed that they are breeding,
Proper anatomy of a dog, Proper nutrition of
animals, inexperienced in breeding any kind of
animals, A heart to do good, but with no knowledge
in which to do it and of course Selective
Breeding goals and techniques( In
general, the owners of the animals use three
strategies to refine local populations:
linebreeding(one bloodline, or strain) or inbreeding
(mating closely related individuals), to facilitate
the weeding-out of undesired characteristics and the
fixation of desired traits. Inbreeding and
linebreeding are controversial aspects of artificial
selection, but have been practiced for
centuries), others are focused exclusively on a
standard and do little genetic screening or Co-efficent
of Inbreeding calculations.
(Results
of inbreeding
Inbreeding may result in a far
higher expression of
deleterious (In the biological and medical
sciences, deleterious means something
harmful, such as:
-
In genetics, a deleterious
mutation, meaning a mutation that results
in a negative consequence for the organism,
usually at the whole animal level.)
recessive
genes within a population than would normally
be expected. As a result first generation inbred
individuals are more likely to show physical and
health defects, including:
-
reduced
fertility both in litter size and in sperm
viability
-
increased genetic
disorders
-
fluctuating
facial asymmetry
-
lower
birth rate
-
higher infant mortality
-
slower growth rate
-
smaller adult size
-
loss of
immune system function.
Natural selection works to remove
individuals who acquire the above types of traits
from the gene pool, therefore many more, in the
first generation of inbreeding, will never live to
reproduce. In biology, the fittest are those who
survive and breed. Over time, with isolation such as
a population bottleneck, caused by purposeful (assortative)
breeding or natural environmental stresses, the
deleterious inherited traits are culled.) Many
working breeds are bred for appearance rather than
working ability. People who have not considered
these factors often stint their breeding stock in
terms of veterinary care and adequate maintenance.
The puppies they produce may have genetic disorders
or undisclosed illnesses, but will often try to sell
their stock before they become evident to buyers.
They rarely screen potential buyers or inform them
on breeds whose care and maintenance may be
inappropriate for their lifestyle.
When such breeding is carried out on
a large scale, the venue is called a PUPPY MILL
(especially in North America) or puppy farm.
Other categories of backyard
breeders noted by dog clubs include parents who wish
to breed animals so that their children can
experience the process. These people may not be
motivated by profit but have not adequately
considered that they may be adding to the population
of unhealthy or unwanted dogs. Backyard breeding is
also blamed for the proliferation of aggressive dogs
for the usually illegal sports of baiting and dog
fighting, and to defend venues of criminal activity.
Aggressive dogs are also important to the macho
image of men in some segments of society. Dog
fanciers generally believe that such ill-bred dogs
are the reason for the bad reputation of some breeds
in the public perception, and the resulting
breed-specific legislation.
Remember...if the price is too good
to be true...there's something wrong.
