Breeders, please, please help with this
 

I bought a Biewer stud last Sept for 2,000. The breeder knew I an experienced breeder purchased the dog for my own stud. I bred him to my females. I had one litter with a PDA so bad the pup died at age 4 weeks. The next litter I lost the only pup at age 3 weeks to a PDA. All is confirmed by my vet and the emergency vet clinic near me. Moms had not delivered pups with PDA before. I contacted the breeder of the stud I bought. She is not willing to do anything, I no longer have a stud I can use and of course can't sell him. Has anyone ever had this problem before? Or can you tell me what you would do. I have bred Yorkies for many years and have never had a PDA or run into a problem like this. I can't sleep, can think, so I turn to you for your advice. Thank you so much in advance.

I'm not a breeder, but if in your shoes, I would have this boy neutered ASAP. If you've bred biewers in the past, and have been keeping accurate records, you'd know if your females lines have produced PDA (sorry, don't know what that is) in the past. You'd know to look for clues in each dam's line, going back a few generations. If that doesn't pinpoint the problem, start looking at the studs lines, and see if any of the dogs in his lines are producing the same problem. That's why an accurate record of breedings and results are needed.

I hope someone more experienced can help with your dilemma.

Here is what it is

I am so sorry you are going through this. I'm sure you've done some research on this condition, and from what I've read the inheritance says complicated; which I would take to mean recessive and or polygenetic.

Obviously you will neuter him, but I think you are worried about whether you should breed your females again or not? The answer to that is going to take a whole lot of research on your part. Obviously you will want to confirm that none of the previous litters have had this problem. Sometimes new owners don't contact breeders when they have encountered a problem. Also how many previous litters have these two females had?

I would want to try to find out more about the inheritance factors for PDA. Have you talked with a specialist to find out the most recent understanding of PDA?

Then I would really research my females lines, to see if this has cropped up in the past.

Once armed with as much information as you can gather, then you will be able to make a more intelligent decision.

In terms of the stud and what the breeder will not do, what does your contract stipulate? Have you contacted the Biewer club for their advice?
I think that I would document all your findings in written form, and formally through a letter to the person who sold you that stud.

It is a tough situation that you find yourself in.

The inheritance of PDA is considered polygenic...which means BOTH of your dogs contributed the gene which resulted in the birth defect.

Thank you!

I just wanted to say I'm so sorry to hear about your litters! I'm sure that had to be devistating as I know I fall in love with those babies as soon as I know they are in mommy.

As far as what to do? I guess I would just neuter the male and move on. Well I'd check my contract first to see if the breeder guaranteed breeding capabilities. If not, then, I'd probably neuter him and keep him as my pet.

Good luck in what you decide.

With this being the case, I would not think that the breeder whom you bought him from can be held totally responsible since your girls evidently carry the gene also. The breeders of the females are equally responsible.

Perhaps you can get her to refund half of the money since he is not breedable.

It really sucks, but I would spay/neuter all parents involved and start over. You don't want to pass this gene on to others.

I might be wrong but in my understanding Polygenetic doesn't mean both "parents" have the gene, but many genes are involved in the inheritance, vs a vs CHD. And there is some talk of Polygenetic recessive and dominant genes, if this bears out a Polygenetic dominant might mean only one side, either female or male are responsible.

This is why I suggested to the OP to get opinions from specialist who are "hopefully" up on the latest research.

This breeder had previous healthy litters (from both females I think). But surely to learn more about this condition, to investigate the latest findings, are all for the good. The "easiest" answer is to neuter/spay all, but is it the most correct answer? Maybe, but I would want to find out all I could before I take that step.

I personally had not heard of this conditon in Yorkies, yet my research on several sites list Yorkies as being at risk along with Maltese and a few other breeds.

Thank you for your answer
 

Thank you for taking the time to post your answer. I will do my best to find out more about PDA. I will contact MSU and hope for a reply.

I would suggest not studding this dog out and fixing him and the female that produced these puppies. It would be horrible to pass something like this on other babies.

This thread is about 8 months old.

Since the dog is up for stud service I thought it would be nice to bring up the post again.

Are you serious? Is there any way to link this thread to wherever she's offering him as stud. How irresponsible. She thought the other breeder was so horrible, and now she's doing the same thing?

Are you 100% sure it's definitely the same dog; you have no doubts whatsoever? If you are completely sure then thankyou for bringing it to others attention! But it would be terrible if it was just that she had been lucky enough to get another Very similar dog...
