Keep them coming!

“The educational links that are on here, do you want others?”

That’s just one of the questions we’ve had about the occasional pages that appear on here. They seem to be liked by both Glen of Imaal Terrier people and folk outside the breed so keep them coming and they’ll go into the file.

Today’s, The Pox of the Popular Sire, follows on nicely from what has been featured previously

  1. Food for thought … especially this paragraph:

    Leroy (2011) has identified popular sires as the single most important contributor to the dissemination of genetic diseases in purebred dogs. Recognizing this, the FCI has issued a recommendation to breeders that no dog should have more offspring (presumably in its lifetime) than equivalent to 5% of the number of puppies registered in the breed during a five-year period …

    Here’s a link to our 10 year registration statistics – NB. this includes importations:

    I have looked back at the past 5 years’ puppy registrations (Winter 2008 BRS to Autumn 2013 BRS inclusive) and had a look at the number of puppies and litters from sires of the past and present – the number in () refers to litters and the % is out of 276:

    No. of puppies registered : 276

    7 (2) 3%

    16 (2) 5%

    40 (9) 14%
    68 (13) 25%
    19 (4) 7%

    49 (7) 18%
    13 (3) 5%
    29 (5) 11%

    45 (9) 16%

    40 (7) 14%
    34 (5) 12%

    33 (7) 12%

    24 (7) 9%
    24 (4) 9%

    A few years ago, the EFG proposed a recommendation (for their Code of Ethics) for a limit on the number of litters sired by a single dog … I can’t remember whether it was 5 or 6 …? (I’m not sure that it ever came into effect … even if it did … well, look at the numbers!).

    Looking at the above figures, the number of puppies produced for a designated number of litters can be quite variable e.g. 7 litters have produced 24 — 33 — 40 — 49 puppies … from 9% up to 18%.

    Currently, the UK breed clubs only breeding guidelines are DNA testing of breeding stock for crd3 and not breeding from a maiden bitch if she would be due to whelp after her sixth birthday (GOITA).

    Should we be more “prescriptive” in our Codes of Ethics …?

    Do other countries’ breed clubs have any breeding recommendations in place …?
