Hi all had my girl mated to day 2nd mating when i got home my boy who has been done got to her. Will my girl be alright from the matings she all ready had.

Both dogs, having mated her could either be the father of any puppy's resulting. The only way the KC will register them is if a DNA test is done to determine who is the sire (And it can vary with individual puppies!)

Depends how long ago your castrated dog was done

my boy was castrated june 2004 i thought by now he would be firing blanks. I just wanted to make sure he would not harm what was all ready there.

Oh sorry, I missed that bit :) Put it down to my age!

You're probably right.  They usually say that a dog is incapable after 3 months but I know of a dog who without doubt sired a litter 11 months after being castrated.  The Vet said that there is always a chance that.......  So you'll not really know without a DNA test.

I thought that once a dog has had the testicles removed then he wouldn't be able to make any more sperm. Does this mean that the sperm can survive a long time after castration.

That appears to be the case.

JG - I found it most strange too but the Vet tested the dog's fertility and still found him to be active after 11 months.  After 15 months the dog was tested again and pronounced infertile!
The dog and bitch were kept together in an isolated (if very large) situation.  There was no way that another male could have visited, which is why the castrated dog was tested in the first place!
I can never make excuses for "accidental" matings - as far as I'm concerned it is always human error and the humans are the ones who are supposed to be responsible!  But in this case the owner, quite reasonably IMO, thought that after 11 months, there wouldn't be a problem!

Blimey! That's astonishing!

Your dogs/bitches seem to be keen as this happened before didn't it?

You could probably get a vet to check to see if your dog's sperm is viable although I don't know if all vets can do this

I think that they only have to look for "swimmers" under a microscope!

Hi Val

I was thinking more of the facilities for collecting it

It's done manually!! *smileeeeeee*!!!

You can have your boys semen tested. Depending on the dog, it can take up to six months for any residue to become infertile - according to my Vet.

What I would like to know is where the hell is this residual sperm stored???

The owner was told that in the dog's body it can "live in the tubes for months"????????  I heard this directly from the breeder (not an idiot) but not directly from the Vet!!!!!  All news to me too, but just thought that I'd share it as the subject came up!!

Maybe the Vet was trying to get himself out of a hole?  I've no idea but the dog and entire bitch lived together for the rest of their lives and did not produce again.

PS It was some time ago and before DNA testing was commonly available here, but the breeder did have 'something' sent to the States (sorry, can't remember what that was) and it was confirmed, through her Vet, that the castrated dog was the sire!!

DNA testing can be done by the Animal Health trust in Newmarket. Cost is £10 per pup/dog. You need to take a cheek swab and the results can take up to 4 weeks to come back. Need to take sample from bitch, both dogs and each puppy.
You can have a litter with two different fathers.

Or a different father to the one that it was presumed was the sire, this happened recently when a badly CEA affected BC puppy was allegedly by a top hill dog stud who had produced many litters without one affected dog over 7 years at stud, the alleged sire was being bad mouthed all over the net but the DNA tests showed he wasn't the sire(good job most triallists & sheepdog people don't condemn a dog without real evidence that cannot be disproved)

It doesn't help the lovely puppy who is almost blind but did clear the stud of being involved in producing him

Did the dog actually mate her?? or did he attempt to. I was just thinking you know how some act almost dominantly but don't mate. Just wondered

DNA test is £20 per pup not £10 as I stated earlier.
