This is a dog pedigree, used by breeders and breed enthusiasts to see the ancestry and line-breeding of that individual dog. The pedigree page also contains links to the dogs siblings and progeny (if any exist). For dog owners with purebred dogs this is an excellent resource to study their dog's lineage.

Morris' Mac 183767 has produced a pup suffering from CEA which makes Mac
a suspected carrier of CEA. If Mac is a carrier then Harriot Roy has a
50% probability of also being a carrier. You can not tell this by an
opthalmic test (vet looking into his eyes). Such an opthalmic test is
compulsory I think in the UK before a dog can be used to breed from and
also before running in the big UK trials. You can only tell that he
isn't a carrier by doing a genetic test (for instance by Optigen in the
USA).
People easily get confused by the statement "he was eye tested" thinking
that he then cannot be a carrier. But if it only was an ophthalmic test,
then he can be a carrier and he can produce children affected by CEA.
This holds for both Mac 183767 and Roy 218222. Where Mac meanwhile has
produced a CEA suffering pup so he is a carrier unless the vet made a
mistake. By the way this could be the case because a CEA carrying dog on
average produces 1 pup suffering CEA on every 100 pups he produces. Mac
produced 350 pups so should have in the order of 3 CEA suffering
children. But he only has one. So it is possible that this single CEA
pup is just a misinterpretation of the vet.
The child of Vic Morris' Mac 183767 that suffered CEA was born in March
1995: Katie 220095. She was probably diagnosed having CEA in 1997. After
1997 Vic Morris' Mac didn't sire any litters.
You can only be sure that a dog isn't a carrier by doing a genetic test.
If I know that a dog was geneticly tested clear, then it will show on
the pedigrees that I compile by a green "e" (older pedigree) or "en"
(CEA-normal on newer pedigrees). If it was geneticly tested to be a
carrier, or proven so because having CEA suffering children, then it
will be shown as a red "e" in the pedigrees.
So if you like to have certainty for Harriot Roy 218222, you should have
him geneticly tested.
Even if Roy gets tested CEA-normal (no carrier) it doesn't tell anything
about the status of his father Mac. Mac could still be a carrier.
I admit that this is complex stuff, but I still hope it helps.
Kind regards,
Teun van den Dool
