Dog Breeding and Hereditary Eye Problems
When you’re into dog breeding, you should be aware that
there will always be potential hereditary problems. Although this is
not true all the time, you should be on the look out for such problems
because it can be passed on to the puppies. Keep on reading and you
will find out what these hereditary problems are.
Firstly, you need to learn as much information as possible about the
particular dog breed you’re handling. Thorough screening is needed so
that you can prevent additional problems in the future. Make sure that
you also look into the bloodlines of your dogs. This is necessary to
ensure the health and condition of the pups.
Eye problems are the most common dilemmas encountered by most dog
breeders. These problems are:
1.) PRA or Progressive
Retinal Atrophy – if this problem is not addressed at an
early stage, your dog can suffer from total blindness. Some breeds are
affected by PRA once they reach 2-3 years or before the breeding
period. In some cases, dogs tend to suffer from PRA when they are
already 4-8 years. If you’re breeding Irish Setters, you’re in luck
because there is already a PRA test which is available to those who
want to breed them. It is vital that breeders identify if their dog is
a carrier of the eye problem. You see, late onset of PRA can affect
2.) CEA or Collie Eye
Anomaly – collie breeds can be affected by this eye
problem which can include the border, bearded, smooth, rough, and
closely related breeds. The condition varies wherein some dogs are
hardly affected but others get completely blind. This problem is
hereditary. Even if the dogs you’re breeding are not suffering from the
CEA but serves as a carrier of the problem, it can produce a pup that
is severely affected by CEA.
3.) Retinal Dysplasia –
eventual blindness is the result of retinal dysplasia. The problem can
start as early as the puppy days of the dog but late onset of the
problem can make it hard to identify which dogs have it.
4.) Entropion and
Ectropion – try to look closely at the eyelids of your
dog. This problem refers to the eyelids turning in (entropion) or out
(ectropion). This eye problem can cause pain.
– you need to identify if your dog has juvenile cataract; if this is
the case, find another dog to breed. Cataracts have different causes
and they are also in different forms.
Every year, dogs should be checked by a vet certified by the AVCO.
Visit the CERF or Canine Eye Registry Foundation if you live in the
United States. Dogs registered under this foundation are free from any
eye problems. It is vital for dogs to be checked annually to ensure
that they are free from eye problems which are considered hereditary.
There are times when the problems show up late but if you consult with
CERF, you’re guaranteed to breed to a dog without potential eye
Dog breeding is serious business. Even if you’re only doing it for
pleasure or as a hobby, you should ensure that the puppies are in best
condition. Who would want to purchase a pup with eye problems? It is
your responsibility to make sure that the parents are not carriers of
the eye problems or are not presently affected by it.
