Hyperuricosuria (HU)
Inherited hyperuricosuria (HU) causes dogs to produce urine with very high levels of uric acid. This can lead to bladder stones, and less frequently kidney stones. The disease is inherited as an autosomal recessive trait. The VetGen test is based on research performed at the University of California Davis which identified the mutation responsible for the disease.
Joybull Kennels take pride in testing all current breeding dogs for HU and undertaking testing for Degenerative Myelopathy
Degenerative Myelopathy - Disease Basics
Degenerative myelopathy is a progressive disease of the spinal cord in older dogs. The disease has an insidious onset typically between 8 and 14 years of age. It begins with a loss of coordination (ataxia) in the hind limbs. The affected dog will wobble when walking, knuckle over or drag the feet. This can first occur in one hind limb and then affect the other. As the disease progresses, the limbs become weak and the dog begins to buckle and has difficulty standing. The weakness gets progressively worse until the dog is unable to walk. The clinical course can range from 6 months to 1 year before dogs become paraplegic. If signs progress for a longer period of time, loss of urinary and fecal continence may occur and eventually weakness will develop in the front limbs. Another key feature of DM is that it is not a painful disease.
What causes Degenerative Myelopathy? Degenerative myelopathy begins with the spinal cord in the thoracic (chest) region. If we look under the microscope at that area of the cord from a dog that has died from DM, we see degeneration of the white matter of the spinal cord. The white matter contains fibers that transmit movement commands from the brain to the limbs and sensory information from the limbs to the brain. |  In the section of a spinal cord from a dog who has died of DM (Left), the degeneration is seen as a loss of the blue color at the edges (arrows) compared with the spinal cord from a normal dog which is blue througout (Right). |
This degeneration consists of both demyelination (stripping away the insulation of these fibers) and axonal loss (loss of the actual fibers), and interferes with the communication between the brain and limbs. Recent research has identified a mutation in a gene that confers a greatly increased risk of developing the disease. How is degenerative myelopathy clinically diagnosed? Degenerative myelopathy is a diagnosis of elimination. We look for other causes of the weakness using diagnostic tests like myelography and MRI. When we have ruled them out, we end up with a presumptive diagnosis of DM. The only way to confirm the diagnosis is to examine the spinal cord under the microscope when a necropsy (autopsy) is performed. There are degenerative changes in the spinal cord characteristic for DM and not typical for some other spinal cord disease. What else can look like degenerative myelopathy? Any disease that affects the dog’s spinal cord can cause similar signs of loss of coordination and weakness. Since many of these diseases can be treated effectively, it is important to pursue the necessary tests to be sure that the dog doesn’t have one of these diseases. The most common cause of hind limb weakness is herniated intervertebral disks. The disks are shock absorbers between the vertebrae in the back. When herniated, they can cause pressure on the spinal cord and weakness or paralysis. Short-legged, long back dogs are prone to slipped disks. A herniated disk can usually be detected with X-rays of the spine and myelogram or by using more advanced imaging such as CT scan or MRI. Other diseases we should consider include tumors, cysts, infections, injuries and stroke. Similar diagnostic procedures will help to diagnose most of these diseases. If necessary, your veterinarian can refer you to a board certified neurologist who can aid in diagnosing degenerative myelopathy. A directory to a neurologist near you can be found at American College of Veterinary Internal Medicine website under the "Find a Specialist Near You" link. How do we treat degenerative myelopathy? There are no treatments that have been clearly shown to stop or slow progression of DM. Although there are a number of approaches that have been tried or recommended on the internet, no scientific evidence exists that they work. The outlook for a dog with DM is still grave. The discovery of a gene that identifies dogs at risk for developing degenerative myelopathy could pave the way for therapeutic trials to prevent the disease from developing. Meanwhile, the quality of life of an affected dog can be improved by measures such as good nursing care, physical rehabilitation, pressure sore prevention, monitoring for urinary infections, and ways to increase mobility through use of harnesses and carts. |
OCTOBER 2012
The UABA has know introduced health testing covering all breeding dogs within the UABA .It is a fantastic initiate on the clubs behalf and the only association that is taking health seriously.Please be aware that when you say you want a Pet then they are sold as Pets and will be provided with a non breeding Health Guarantee. All our pups are graded and sold accordingly..not all pups will be breed quality. Pups that are sold as pets will receive a breed certificate once the pup has been desexed. To many people are wanting to cash in on this breed and have no or little dog knowledge.
Breeders that are wanting to add a special pup to their kennel will receive a Breeders Health Guarantee and a breed certificate on purchase.If you are interested in the Breed but not a breeder than I am willing to be a mentor but only one pup sold per litter will be available under these terms.
JUNE 2012
All dogs are now hip and elbow scored before any prior mating has occurred.
Joybull kennels are aiming to use dogs with scores less than 50 and a combined score less then 80. This score will be improved as more generations are being born. Our stud dogs score 19 and 20.
All dogs are medically examined at 12 months .Trachea and soft palette is examined under an anaesthetic prior to breeding.
All dogs are excluded from breeding under the Joybull Kennel if they have been treated for juvenile demadex.
All puppies are sold with a 12 month health Guarantee.
Health Screening under Bulldogs Australia is leading the way for a healthier more sound bulldog.
Do your research before handing over your hard earned cash for a Bulldog.

Winstons hip score came in at 24. His right side was 17 and left 7. this was due to a shallow socket. I plan to xray Precious and Kissy ( daughters ) at 12 months.
15th July, 2008
i have recently xrayed Winstons Hip and elbows. The xrays have been sent of to be scored but expecting him to come in around 30. He showed no hip dysplasia but does have shallow hips and a little loose on the left side which will bring his score up. Will put results up when I receive them.
Once he has sired a litter of pups he will be available for stud.
At present there is no mandatory health screening in the Aussie Bulldog. 26 th march 2008
This topic has been discussed and hopefully in the near future all owners of breeding stock will start to hip and elbow score. Data than can be gathered over a period of time to find the average . This average is what breeders will use to eliminate high scoring dogs from their breeding program. With the purpose of breeding more sound dogs with less incidence of dysplasia.
I plan to hip and elbow score my dogs between the ages of 12-18 months.
In the history of the making of the Aussie Bulldog it is apparent that some stud dogs were used that had undesirable genetic traits or faults. The outstanding quality of these dogs made these faults seem small compared to the advantage of using these dogs over females.
It is no longer the case now, the way the Aussie is bred today should reflect on healthy matings between a sound dog and bitch with good conformation, The breed has continued to grow in strength and we do have more choices in our matings.
No longer should breeders be mating dogs that are deaf, cryptoidism or suffer from Demodex.
You will find any genuine breeder will remove these dogs from their breeding programs.
Unfortunately with all the rigid planning that goes into matings these traits may still occur rarely in pups stemming back from dogs used in the past.
