UCDavis Havanese Genetics

One of my concerns about breeding for genetic outliers and diversity was the possibility of bringing back some of the earlier health issues like liver problems. How delighted I was today when the litter between Bailemos Pretty Fly for a White Guy and Giocoso's Joy for Sonnrisas had their ammonia test for liver function. Any value below 60umoL/L is considered a great functioning livre. The highest reading from this litter was 18. The puppy exam went extremely well yesterda...y and now we sit back and watch them grow up. This is an extremely important breeding to me and even if you don't understand the chart below, these two dogs are consider completely unrelated. All my breedings have been 10s or unrelated, but this is the one with the most "outliers" or rare genes. The conformation evaluator comes on Saturday (out in the sunroom without other humans around) and we will see what she has to say. I see some really, really nice stuff, but hope to confirm now that they are 8 weeks. In all the "unrelated" breedings I've done they are all typey and definitely look like Havanese. Now that they are all tested, if I did want to do a line breeding I could do so with more confidence since the diversity, even within a litter is amazing sometimes with familial cousins being unrelated and yet dogs with no common ancestry can be like cousins and sometimes brother/sister.

Subject Short forelegs From [email protected] contact To HFC Group Add contact Date Today 07:53 There is no doubt that this article is true and we can already test for this particular FGF4 gene (UCDavis Havanese health - CDPA and IVVD), I think the article puts an emphasis on allowing longer legs over testing for the genes. Both are the same gene, it is just that they are found I n different locations. The IVVD form or location of ...the FGF4 gene produces 20 times the protein that the same gene by a different name(CDPA) does, thus potentially causing more severe consequences. Having said all that, it is most likely next to impossible to eliminate the CDPA gene from the gene pool. We can get rid of the stronger IVVD gene since it is only found in about 10% of the population. However, it doesn’t mean that we can’t take a slow, well informed path to handling all this. Simply allowing longer legs, thus taller Havanese is only an insidental part of the solution. Testing for the genes and ensuring diversity is our only option at this time. https://cgejournal.biomedcentral.com///s40575-020-00097-5

I love having a genetics lab I can trust.

Not a genetics issue but ....Despite very strong words to my puppy buyers about these medications, I just received another report about Simparica flea and tick. The reactions ranged from mild to fairly severe to the point where they thought they would lose the dog. Has anyone every measured the amount of poisons per pound of body weight some people put into their dog's body?

It has recently been brought to my attention by a Toy Poodle breeder that the IVDD (intervertebral disc disease) test done by Embark is seriously flawed and CAN NOT BE relied upon. This can have huge implication for breeders that are making (breeding) decisions based on those results. University of California Davis, researchers stand behind the discovery of genetic mutation found across the breeds (gene implicated in the risk of developing IVDD, in what way exactly is still u...nder research). The test done by UCDavis lab is testing for this very genetic mutation. Embark does NOT test for direct mutation, but instead does a linked haplotype/marker test. Details: The breeder I mentioned has results of 23 Toy Poodles from 3 different breeders, tested for IVDD both by UCDavis as by Embark. She writes: ' Some show one copy (of IVDD) for both companies. Some are clear with Embark and two copies with VGL (UCDavis). Or clear with Embark but one copy from VGL. 8 out of 23 dogs were 'right' (as in matching results from both companies). The other 15 were wrong. Please feel free to share this post as this is a very serious issue and breeders should know about it. I have made it public for this purpose.

My next project is to create a website explaining all the colors of Havanese based on those Havanese who have actually been color tested. I would be so grateful to those who feel free to share pictures of their Havanese along with the color testing. I hope by organizing the entire site according to accepted rules of dominance, it will be easy to follow and apply to your own dogs. Hopefully pictures of mating pairs and their offspring will be available as well, so that we c...an experience the possible outcomes for all colors and patterns. I am especially interested in dogs who turn grey about one year of age. This is often attributed to a gene called "G" and assumed to be dominant. In my very limited experience it does not act like a dominant gene, and as an example Mojo only produce one grey dog that I am aware of. If you do not want the dog's photo posted, but are willing to send it to me to see privately, that will help as well. Any dogs that are unusual in color or pattern please feel free to share even if not color tested. If really interesting, I may be willing to pay for the testing myself. For instance in some breeds there is a "grizzling" gene and years ago I saw a Havanese that seemed to be similarly marked. If you send pictures, please be sure to say "Free to use with my name" ; "Free to use without my name"; Please use for your information only". Thanks Everyone. See more
