...which according to the notice on my vet's notice board these puppies are much better than the purebred ancestors because they won't have their health problems! Just looking at the photos was enough to worry me. I took it up as tactfully as I could with the receptionist to ask whether the vets actually endorse this line of thinking and got a rolling of eyes, but the fact is that by displaying the card they aren't challenging the statement. Has anyone else had this nonsense and is there a way of persuading vets to disown this kind of claim?

Not the same but it bothered me the other day to see a notice on my vet's notice board for a Labrador available for stud. NO health tests done whatsoever. Surely a vet practice should not accept that!

I suppose the advertisers could have been clients of your vets and therefore spending money with the practice.
My vet has a board in their surgery for adverts but also display a disclaimer to say they aren't personally recommending anyone.

when i went to wilko last they had four litters of sbt and one lot of crosses. No really the right place to advertise puppies is it, they said they have no control over whats ads are placed on there board?!!

same at PAH
Although not doggy related I was furious when I saw that in the middle of the store they were selling lovely fluffy bunnies, and at the back of the store they had (in what was nothing more than a dark cupboard) rabbits for rehoming.

Odd... assuming you mean Wilkinsons... the one in my town has a note on the board saying theyw ill NOT accept adverts for animals (which surprised me I have to say!) at all.

The awkward git in me says you should see if youc an put up an ad for an Escort *ahem* agency... or a request for used underwear - Methinks they would suddenly find they DO have control over what is advertised!

Sorry to butt in ................but since I do own the 'lier' part of this mix I feel qualified to post.

Given the huge health problems in the breed and the fact that it  seems as though most Cavaliers carry at least some genes for both serious conditions affecting them, a cross between a Cavalier and any other breed is far less likely to produce clinical cases of either disease...sad but Im sorry to have to say.......True !!

So to compare a pure bred litter from untested Cavaliers and a litter of crosses, im afraid the crosses win.

took my two charlies(not cavs) into our local shops today,had 16wk old mabel in my arms,waiting ouside m&S while friend was in there.woman stopped to stroke them saying are they pug/cavalier crosses as she has 2 crossed with a cavalier,they bought them as they dont have the associated health problems of the 2 breeds. i put her straight that my 2 werent crosses but pure kcs,and wished her luck with her 2! (wasnt in the mood to debate with her after the week weve had..)

That surprises me, in my ignorance I thought there was a 50% chances of defective genes being passed on, plus any other oddity that arises form the mix, anatomical anomalies for example, what ever the odds it still seems like a Russian Roulette for the dogs to me.

Not a criticism, just an uneducated observation.

The traits will be passed on to a certain proportion of the puppies in a cross, but are unlikely to be expressed in the first generation, unless both breeds carry the same health issues.

Use these crosses for breeding then you may be passing on both breeds problems.

Oh dear, yes Charlies will be mistaken for pugaliers if that cross takes off. And what's the point of it, it's just recreating the Charlie which we already have as a proper breed!!

So if you cross 2 cavachons(for example) where 2 of the grandparents are untested cavaliers you could possibly end up with puppies with heart murmurs/SM?

Yes indeed. Not as likely though as mating two Cavaliers with MVD.

In a polygenic disease like MVD a dog can be pass on some - most - or all of the copies of the genes needed to produce a clinical case. It depends on the numbers of copies of the genes carried by the individual.

but with simple recessive conditions which many are the next generation of breeding would produce some affected.
