Zamp - cause of death? - Page 2

The stud restriction levels in Germany are: 60 German Registered Females and 20 Foreign Females per year. These figures may be up or down 10, but that's almost the same in the bigger picture. That being the case, a stud dog can do on average not more than say 2 females per week.

Any male mammal with a healthy level of testosterone should be pretty comfortable with that; given that these stud dogs don't have to chase the female target for kms in the forest, fight with competition before getting what they want!! Adversely, they are served the 'princes' on a platter without much fuss, then go back to their quarters and rest.

Wish we could have it so easy!!!

These are SV rather than German KC (VDH) guideliness presumably?

Assuming 5 per litter (not sure what the average is) that could amount to more than 2000 puppies per stud dog in a breeding lifetime.

The FCI has recently recommended that no dog should sire more than 5 per cent of a breed's puppies in any five-year-period. Given that GSDs are a-plenty, it may be that 2000 would not exceed this, but it does sound quite a lot to me.

It may surprise you but the figures given out by the FCI are based on studies of the actual results of the amount of matings and the possibility of the given numbers of offspring based on the average puppies per litter previously recorded. This is not a figure they have just decided on, but a figure which allows the current successful breeding practice to continue. I am always suspicious when people quote guidelines given by a governing body and seem to think they found another way to inform us that our house is not in order. The main thing with Top Stud dogs which are used at stud more than others is that you are more likely to see and hear about  the results much sooner and get a fairly good idea of the results good or bad. The idea that we should use different dogs more often as opposed to using the best ( Working or Show) would be less of a benefit for identifying hereditary diseases as well as the loss of their desired hereditary traits, again this could apply to Working or Show dogs.

Yes, those are SV restrictions.

2000 does not exceed 5% of the GSD breed's puppies in a 5 year span, much less a dog's normal breeding span of maybe 8-10 years.

In the US (and probably Canada), the country is large enough that geographic restrictions usually dictate that no one stud dog gets that many breedings. And AI with chilled semen is not enough of a solution--its expense minimizes its use (I recently estimated that to use chilled semen would cost about $1300, on top of any other expenses or stud fees. Not impossible, but enough to make one look for another stud dog option if there is a suitable one available.)

Also, do not consider the numbers here on the database to be highly reliable. Many dogs are missing and many are duplicated. Please seek a more reliable source of information for any article you might write.

Hi Jemima and all!

It is NOT correct to assume that Canto von der Wienerau only had 120 progeny.

120 Dogs may have been registered HERE on the Pedigreedatabase or in other databases like the WinsSis, but this figure is certainly NOT correct.
These databases have pointed out he sired certain dogs (thus registering him as a sire in the database), totalling 120 pups, but it is incomplete. One cannot even refer to the SV-Genetics for other numbers, as this particular database only features offspring born after 1985-1986 (thus including only a few important parents for dogs in the database). So one should contact the SV for detailed and correct information on this particular dog.

120 pups, at approximately an average of 5 pups per litter would equal only 24 stud jobs. Even if Canto died at the very young age, he was in the very Centre of the Business, in Viernheim (brothers Martin), and in a 2 year period, he must have studded a huge amount of females, and sired at least  300-400 pups in a two-year-period.

Hope this helps.

P.S.: To my knowledge, the maximum allowed amount of stud jobs in the SV are 60 domestic and 30 for foreign females, totalling 90 per year. Hope I'm up to date with this info.

There is also the apparently minor matter that dogs, healthy or otherwise, have mothers as well as fathers, in fact it is the females who pass on Haemophilia for example.

Margaret, NOT TRUE.

The females CARRY it, but do not usually suffer from it, unless both alleles on the X chromosome carry the hemophilia gene. As the males have only one X chromosome, they will be affected, as there is no second X chromosome to mask it. (Males are XY, females XX as far as the sex chromosomes go.)

Since the males will be affected, it should be easy to spot the disease, and just NOT USE affected studs. This obviously did not happen in Canto's case. He was used extensively until he died.
