It seems in our attempt to control dog populations we are created other problems for our dogs:

What is the difference between North America and Europe and why do they seem to be able to cope with this while we in North America can not?

UCDavis Genetic Project
Havanese and Autoimmune Problems
Common
autoimmune conditions include autoimmune hemolytic anemia, sebaceous adenitis,
diabetes, inflammatory bowel disease, and the most common of all, autoimmune
thyroiditis to name just a few. Anyone
who has been on the pet Havanese lists has heard of all of these and more in
our breed. If there is one case we know
about, there are probably many, many more.
So, is this something we should be concerned about as breeders? And, if so, what do we do about it?
First,
let’s look at other breeds that have similar problems including the Standard
Poodle, and the Italian Greyhounds. What have they done? The department of genetics at UCDavis under
the guidance of Dr. Niels C. Pedersen has developed a genome wide genetic
diversity test geared specifically for the standard poodles and the Greyhounds:
How this works and what is different to the other
services that have been offered is that while the UCDavis study looks at the
entire genome, it also pays particular attention to the MHC (major
histocompatibility complex) which contains many of the genes that protect our
dogs from external assaults such as viruses.
But
sometimes an immune system goes crazy and can’t tell a foreign body like a
virus, from the animal’s own cells. The
result may be an auto (self) immune condition like those mentioned above.
Why
this is most challenging for breeders is twofold. We may see different conditions in different
litters or even in the same litter and not realize that what causes them may be
related. While one dog may have
thyroiditis, another may suffer from SA (sebaceous adenitis). The second
problem is that many of these conditions tend to occur in the more mature dogs
and most need to have some type of trigger.
So even in two genetically identical clones, one may experience
thyroiditis and the other not.
So
what can we do about it? Many geneticists
generally accept that most autoimmune problems are a result of a general lack
of genetic diversity, especially in the MHC.
So how do we maintain a diverse immune system in our dogs and still
maintain the characteristics we want, the beautiful structure, coat and
personality of our breed? One way is to
build a picture of the Havanese genome to see what genes we actually have across
the entire genome and in the MHC area. Once we know that, then by testing all
potential mating pairs, we can ensure that while maintaining the quality and
structure we want for our dogs, we can
also ensure that each new breeding brings us as much diversity as possible. But
aren’t we doing that using COI (Coefficient of Inbreeding) to guide us? COI simply shows us the probability that any
two dogs are genetically similar or dissimilar.
With genetic testing we have a much more accurate idea of the diversity
level of any mating pair.
First,
however, we need to find just what set of genes exist within our particular
breed and to do that we can take
advantage of the program at UCDavis developed in conjunction with the Standard Poodle breeders, and the Italian
Greyhound breeders. Akita, Black Russian Terrier, Golden Retriever, and Alaskan
Klee Kai breeders have also started studies through UCDavis.
There
is a group of people who have already joined together to try to see this
accomplished. You can find out more about them through the Facebook group “HavaneseGeneticsUCDavis”, whose members are from almost every country where Havanese
can be found. You may also contact me as
coordinator for North America or Senija Hodzic in Holland who is responsible
for the European segment of the Havanese population.
The
goal is to find every unique gene so that we know what we have to work with. To get
started we need as diverse a sample population as possible which includes
Havanese from all countries where they exist, and from all the unique lines
within those countries. Many dogs from the same breeder or family is not the
goal in this initial step. We need at
the very minimum 100 dogs, but 400 would be better. The initial cost will be $50 per dog and some
volunteers are already working on gaining financial assistance where needed. The goal is to find every unique gene that
exists within the world-wide family of Havanese. Once that is achieved then genetic analysis
will be made available so that each breeder with be able to judge the diversity
level between possible breeding pairs and hopefully choose the dogs found to be
the most diverse.

Sorry, they didn't turn out very well, but we taking the dogs out to the pool right now.

Liver information
Liver information
This is extremely important to understand that the liver is a reactive organ. There are times when liver values are higher than normal, but this can be normal ESPECIALLY IN A PUPPY. Read the above article and don't automatically sign up for many, many tests just because one of the values is high. Worm medication, vaccines, bacterial or viral infections and even eating something the puppy shouldn't be eating, can send liver enzymes up. I check to make sure that the puppy livers are working properly before they leave here so please do not spend lots of money on liver tests or, heaven forbid, biopsies as has happened in several cases.

Auntie Charo loves the puppies
Lusa wan't too sure about Charo going into the whelping box, but Charo persisted and is now helping Lusa take care of the pups. Good girl Charo.

What a weekend!
First George finished his intermediate Jumpers with Weaves title in agility and then his daughter, Parti, earned a group three. Parti was bred by Liz Barry and is owned by Brian Scott.
Puppies are three weeks today
Now this is the really fun stage. The pups are seeing us and responding and seeing the world for the first time. They also will begin to hear when their ears open.

Puppies are beginning to respond to us and to each other
The two active puppies are Flynn (the brown one ) and Jack (the black and white one).
