I know somebody who is getting a yorkiepoo and not in a position to have a 'chat' with the people but thought I would send them a link to all the health tests for both breeds to make sure at least both parents have all the relevant tests so can anybody  help with links to all the tests for both breeds please.

Thanks

Lucy

Lucy I am sure this information is available on the KC site and the breed clubs will go into the matter further, however people have been told that crossbreeds are healthy so I would not expect too much from your efforts.

I am hoping these people will as the message will be going via somebody they know well where as they don't know me so hopefully they will take the advice onboard

Haven't looked at the breed clubs' websites - but looking elsewhere, firstly the risk of PRA is common to both breeds.

Heart problems in Yorkies plus Portosystemic shunt, and Von Willebrands and hips to look out for on the Poodle side.

I don't know offhand if the heart problems, liver shunt and VWB are down to recessive factors or not (which is what those who do these crosses are assuming), therefore they could possibly occur. Genes are not all dominant and recessive - there are threshold characters and variable expression to take account of.

A|t the very least the parents should be eye tested and clear of PRA.

and patellas should be checked in most toy/small breeds.

Totally agree Barbara.  Having kept various toy breeds over many years, I have had patella operations of both Yorkshire Terriers and Toy Poodles.  Never bred from them, obviously, but it is why I am so keen to get a line with knees that are knees!! 

Have to say that PRA has only raised it's ugly head in a Toy Poodle.  A well known line too.  I had him castrated, he was a pet, and there was no intention to breed from him anyway.

http://www.ytca.org/health_screeningclinics.html - The UK website holds nothing on health tests, really poor!! I have linked in for the American site which covers Patella testing and CERF eye tests, not sure what for and they even mention about hip scoring too!!  I was reading on one site about liver shunt testing, if this is the case the whole litter should be done before they are even looked at by prospective owners.

Liver shunt is not restricted to dogs. The aunt of a kitten I bought a long time ago had an operation to fix this; it was so rare in cats back then, that I didn't take it on board that it can be hereditary.

The KC doesn't list any tests for Yorkies.
The KC lists DNA for PRA and suggests eye testing for both toy and miniature poodles.

If you search for my very recent post asking about health testing you will find the link to the KC

The KC doesn't list any tests for Yorkies.

More's the pity. I don't think ANY toybreed should be bred from without having been eye tested and checked for luxating patellae. (Also a shame there is no official scheme for patella.) I eye test my Papillons despite not "having" to, and last time I took a couple to be done Professor Bedford told me that yes, there has indeed been a few cases of PRA seen in the breed -but as none of them have been diagnosed under the official scheme and therefore not reported back to the KC, officially the cases don't exist and therefore there is no requirement for testing.  It's bound to be the same in other breeds. The only way to play reasonably safe is to test.

I agree Marianne that all breeds should have the basics of Hip scoring and eye testing.

With the eye testing surely all results should be reported, not just those where a breed is officially listed as being affected by a certain issue.

As for Patella's there is a scheme working fine in USA under OFA, so I really don't understand why we don't have one here.

I sent a bitch to the USA and even though it's not a breed issue her owners had her patella and elbow tested in addition to Hip eyes, DNA for prcd-PRA and thyroid levels.

Of interest to you may be the fact that a Friend of mien had her Terv and Groen bitches eye tested and both failed for HC, this was before anyone was eye testing Belgians.  Our ringcraft ran an eye testing session and it was picked up.

Can I just ask what you would ask a breeder regarding patella testing if you were enquiring about a puppy, and what are the eye tests and do they still need doing if the parents have been DNA tested for PRA ?

My breed is only listed for PRA and we have a DNA test for prcd-PRA. 

The breed club still want annual eye testing to check for any emerging conditions, and it is thought there is likely to be more than one form of PRA in the breed, based on historical evidence of difference in presenting opthalmic signs and ages of onset. 

The prcd-PRA being late onset, and historically we did have cases of early onset.

So any breed with DNA tests for some eye conditions ideally would continue to eye test for anything else.

I believe there is an accepted veterinary scale of parameters for patellas, even though there is no official scheme.

Don't think you would ever find anyone who is crossing breeds that will have bothered to do all health tests or even any because those who care for a breed and  do health testing would not dream of cross-breeding.

Those who cross breed to produce designer pups are only interested in their bank accounts and health testing would cost what to them would be an unnecessary outlay as would buying quality stock to use for such a purpose.

So the dams and sires used to produce these expensive props to the purchasers ego will be poor quality examples of the breed who may or may not be healthy as no one will have checked. The only thing certain about it is the purchaser will pay through the nose for a cross-breed or possible a mongrel.

I know and doubt they will have health tested. It is just putting some information on it for them to look at so at least they are aware !

Good news that the people are going to ask about health tests so at least they have taken on board the information I gave them so thanks everybody and hope they make the right decision :-)

That is what people don't realise, it isn't that pedigree dog breeders have anything against cross bred dogs per se, but why would someone with a quality bitch especially, whose breeding capacity is limited waste her potential (and take the risks associated with breeding) on producing cross bred puppies with no particular purpose beyond reproduction, and their saleability? 

The reason that so many of these cross breed breeders are doing it is because they seem to be able to get twice the price for the pups, than they would for poor quality purebred pups with  no health testing or record of achievement.
