Imported Stud Impotence/infertility - More Common?

[Rebanne]

ok what about pups that are imported into Australia becoming fetile and sring litters when mature...but adults whom have previously sired a litter, then after all the vaccinations done become sterile...I would have thought puppies would have been more likly to suffer from the effects of vaccinations than older/mature dogs?

well they might but they also would have had less then an adult who was 3 or 4.

We must be lucky in our breed I think. Every single import, both male and female, with the exception of the first, and one male who died young (so never tried), have had successful litters. Oh, sorry, and the most recent who has only just arrived :laugh: .

I think the age would depend on the country the pup is exported from, of course adding what our requirements are.

The pups we saw from England were never rabies vaccinated until now.

I say vaccine,one in particular is known to affect the mobility for atleast 6 months.

I do now of an import whose mobility was very poor but after time & guidance from a reproductive person produced a litter of 10 in a breed where that is massive.

I should add this dog travelled 3 countries before coming here

There are some tablets that also affect sperm mobility,If any of our males have required meds our vet always asked about up coming stud work & how the meds prescribed could be an issue & whether there may be an alternative if required

I happened upon an interesting discussion here on sterility in stud dogs which made me think of this thread.

One of the things discussed is that dogs on ivomectin based hearworm meds may test as sterile while on them.

It is possible I guess, that if the dog remains on the meds and continues to test as sterile, that the connection would not be made.

It may be worth 'testing' a dog by, for example, taking the dog off them over the winter months and retesting their sperm, or switching to a different type of heartworm med?

At least then it could be ruled out as being an issue or not I guess.

I have had my dogs on Ivomectin for all their lives and still siring at all ages. :)

Anything is worth the thought and thank you espinay2 for yours, maybe it may be in some cases not all.

A lot of the products for heartworm are ivomectin based.

I also recall a dog in the states that went sterile and it was traced back to the heat of the water the dog was hydro bathed in. Smart repo vet worked it out. The dog did return to siring live litters.

Again we have a thought where heat/rise in temparature was the culprit. By the way the dog was a heavily coated breed that was bathed in very hot water to stimulate the coat growth.

[espinay2]

Yes, the hot water case was another possible cause that was mentioned. Also mycoplasma infection (which antibiotics fixed). I think there are so many possible causes that many cases will be different. Some dogs will react differently and what one dog may manage, another may not. If dogs are on HW meds and are not sterile then obviously it is not an issue for THEM. There were quite a number of people mentioning cases where heartworm meds seemed to be the culprit that it may be worth investigating if trying to find a cause in a dog that IS sterile, rather than instantly ruling out a dog as irreparably infertile.

Also too we don't know what the effect of having multiple treatments for different things done at once can do. The case in the health forum of dogs which died as a result of the combination of worming tablets and 'flea bomb' (whatever that was - no clarification given) is an example of how when put together some things can overload a system. Dogs being imported do have their system quite overloaded (worming, parasite treament, vaccinations, stress) so it is certainly possible that this overload could have an effect in some dogs, while some others handle it fine (just as some dogs suffer from vaccinosis while others on the same protocol do not etc etc)

Espinay2, yes your quite right it may be one thing or a combination of many things. My mind keeps telling me just watch and wait and see what may happen with the imports from England now they have a similar protocol to the States.

It may be an eyeopener for all of us. Along with many things, only time will tell. :)

[steppenwolfstaffords]

ive heard of a proven dog that came to aust from europe was proven, used here but never produced a pup, sent back and then produced back home ???

Another of a proven import from the usa sent here and was sterile but then started working again...
