Health tests and information
We health test all our dogs of any breed we own. I do feel lots of people mis interpret health tests, so I hope this page will help those of you that do not quite understand the reason of health testing, why we do them, and what they mean.
Firstly a health test is for the breeders records and they are a tool for us to avoid inherited conditions in animals. Their are relatively few health tests for each breed available. But most aren't even recorded with the Kennel club of Great Britain. So these then become private health tests which the breeder holds on record and their is no online record of them being done. They are only recorded with the Kennel club if its a kennel club required test. You can submit the health tests to the Kennel club, but they are held on private file only.
When you go and visit your puppy, or pick a puppy up, ask to see copies of the health tests. Remember do not accept excuses why health tests aren't to view. We have all ours in a file for people to look through.
The Kennel club required test for Hungarian Vizsla is Hip scoring and glaucoma testing.
The Kennel club required test for Pugs is Boas and PDE.
The Kennel club required test for Bracco Italiano is nothing.
The Kennel club required test for French bulldogs is Hereditary Cateracts, BVA eye testing, from Jan 2021 Boas. They have dropped Degenerative myopathy.
Now when I say a required test what does this mean? It is for assured breeders only. Anyone can still register a dog of any breed with no health tests and get registration papers.
DNA tests and what results mean to you, if we work in 1 in 4.
If you mate a clear to a clear you can only get clear puppies.
If you mate a clear to a carrier you will get clear puppies.
If you mate a carrier to a carrier you will get 1 clear puppy, 2 carriers, 1 effected.
If you mate a effected to effected you will get 4 puppies effected.
The twist to all of the above is although we have said 1 in 4, in fact it could be 1 in 1000 according to my scientist son in law that did genetics. This is why for many generations something will not appear, then by luck of the gods it can do such as hip dysplasia.
If you are buying a puppy to breed from in the future knowing their status of the health test is important because you will need to know if your dog is a carrier. So ideally you want a puppy from a clear to clear mating or a carrier to clear mating. You do not want an effected to effected, or carrier to carrier. If you have fallen in love with a puppy and it comes from a carrier to carrier mating then you should dna test the puppy in the breeders home first which will give you the result as you do not want to purchase an effected puppy. If it is a carrier you just mate to a clear.
Now why do we mate clears to clears, and carriers to clears? Simply because the gene pool in the UK is not large enough in pedigree dogs and by reducing the gene pool we could increase epilepsy and many many other health problems, as the gene pool just got small. So its very important to use carriers in our breeding programs and not ignore them. Its no good eradicating one disease to introduce ten others. This happened in a breed in the uk and the breed club advised all breeders only mate to clears, and suddenly the gene pool got so small that they then introduced many many more dogs with epilepsy and other health problems. So we need to understand our tests and use them as tools. A carrier will not suddenly turn into effected, so owning one you would never know it has a gene to produce say PDE if put to another PDE carrier.
So are all cross breeds healthy? Absolutely not, and because many now days are bred from pedigree dogs effected by genetic disease they can produce it, or introduce it into their puppies by the dogs they mate together. Luckily some very wise cross breeders are now doing the health testing for their breeds. But the majority of cross breeders start cross breeding because they do not have to do the health tests, and its more money in their pockets. I have seen more cross breeds with temperament issues, as well as health issues. Temperament can be unpredictable sadly, as the genes thrown together are a cross
What does a breed average mean? It simply means out of 1000 dogs health tested, its the average score from all those dogs, which is not always accurate. For example if only 2 dogs are health tested in a year as its a test not done by that breed, the score could be high, but still normal. As we found out in Pugs. What is important is knowing the generations behind, and knowing and understanding that an even score is actually more important than a low score one side and high the other. A breed average score can change over the years as more dogs are scored. For example I remember when Vizsla were 15.
Some tests are new and data being collected for the future. For example BOAS in Pugs and French bulldogs. This test can be interpreted by one vet to be 1 result yet another vet could say something completely different. So it is not categorically correct....YET.! This is so new that they are years away from really discovering the cause of this. For example for years they thought flat faces were the cause, not questions as to this may not be the case. In another ten years the data will then hopefully be making a difference to those dog breeds.
Can the Kennel club refuse registration? No they cant or wont. The only time would be if you mated a mother and son together or a daughter and father. Or if you mate your bitch twice in 12 month period, then they could say no, but often they register them.
Can results be false ? Some yes they can because with some dna tests it means that the dog is unlikely to get the health issue, so it could go through life fine, then get it. But it is unlikely too. You can mate a higher hip score dog to a lower score and get all good scores. Eye tests which are visual can change. Then we have vets who are hip scoring or elbow scoring, and the bva are scoring wrongly. Or putting on points which other vets wouldn’t do. Pushing the scores up higher. So it can be down to interpretation.
Some dogs with health tests on the higher side, produce offspring low. So a lot of the tests are inaccurate.
You have to trust your breeder that they know what they are doing, but sadly today it seems many people setting up breeding dont have a clue about health tests. I read just today where a woman is mating her dog, but wont bother with hip scores because she wont put her dog under for hip scoring. She is being silly because you can find vets that sedate only, and if her bitch has to have a c section then it will have a GA so she should hip score her bitch. I also read I’m not a breeder so I haven’t done the health tests. Yet bred the dog, so if you have just 1 litter lets make it clear you are a breeder. Stop skirting around words so you do not get yourself a license, and you must submit a tax return. Another lady bred her frenchie and was selling them on social media, but not a single health test done. But charging 5000 a puppy. That price is higher than someone who is doing it right and health testing.
