HEALTH ISSUES
IN THE STAFFORDSHIRE BULL TERRIER
The Staffordshire Bull Terrier is by nature a robust
and healthy breed. However there are a couple of hereditary health issues
which you need to be aware of if you are considering buying a new puppy
or planning to breed from your bitch.
Report from
1.
L-2-HGA Hydroxyglutaric Aciduria In the past few
years a small number of Staffords have been diagnosed with a metabolic
disorder, its clinical name is L2 hydroxyglutaric aciduria or L-2-HGA.
This condition manifests itself in varied ways with affected dogs displaying
behavioural changes and dementia, anxiety attacks, having full blown
seizures, as well as exercise intolerance and ataxia (unsteady gait),
tremors and muscular stiffness. Dogs from totally different bloodlines
have been found to be sufferers and the number of affected dogs diagnosed
has risen. The disorder (and a similar linked disorder D-2 HGA) is found
in humans, again very rare, but nevertheless devastating for those families
affected by it. The disorder has an autosomal recessive method of inheritance,
which means that both parents must be carriers of the affected gene
to produce affected offspring. Through excessive
hard work not only on behalf of the Animal Health Trust at Newmarket
and by people submitting blood and urine samples from the families of
affected animals a genetic test has been determined to identify the
carriers of the gene which causes L-2-HGA. IT IS THEREFORE
ADVISABLE THAT ALL BREEDING STOCK BE SCREENED IN ORDER TO ERADICATE
THIS CONDITION IN THE FUTURE. It is known that
HC is inherited by and automal recessive path (i.e. both parents must
be carriers of the defective gene to produce and affected offspring).
HC is a progressive condition and this means that although a puppy is
not born with cataracts they will start to develop at a juvenile age.
(maybe from 8 months onwards), and will progress until the dog is totally
blind. This condition is bilateral which means is affects both eyes
equally. Thanks to the tireless research by the Animal Health Trust
in Newmarket there is a now a DNA Test for Hereditary Cataracts. The mode of inheritance
of PHPV is not so clear, but it is known that it is a congenital condition
(present at birth) and that it is not progressive. This means that if
a puppy is born with PHPV it can be detected by ophthalmic screening
from 6 weeks of age and if it is affected, whatever the condition of
the problem at that stage it will not change throughout the dogs life.
Either of the above
conditions can be operated on, but it is a serious operation and can
be traumatic and very expensive. It is not always covered by insurance
due to the hereditary nature. Even though the
genetic test is now available for Hereditary Cataracts it is still important
to screen for PHPV. This type of cataracts
is found in other breeds, particularly the Labrador and Golden Retriever. Here are some of The Kennel Club rules on breeding Before thinking about breeding from your bitch, you should acquaint yourself with the Kennel Club Regulations on registering litters and the registration system in general. A Guide to Litter Registration can be obtained from the Kennel Club, but you will need to remember that the Kennel Club will not accept an application to register a litter when: a) The bitch has already whelped six litters, or b) The bitch was under a year old at the date of mating, or c) The bitch has already reached the age of eight years at the date of whelping. N.B. Relief from the last restriction may be considered provided the dam has previously whelped at least one other registered litter, and a written application is made prior to mating and supported by veterinary evidence confirming the suitability of the bitch involved in the proposed whelping. You will also need to ensure that your bitch's Kennel Club registration does not carry a breeding restriction (endorsement). If there are any, you will need to discuss this further with the person from whom you obtained the bitch, as any breeding endorsement will need to be removed before registration of a litter can take place. In most cases it will be the breeder who has placed the endorsement, and who will therefore be the person empowered to remove it.
This can be done by submitting a blood sample to the AHT at Newmarket.

TESTING
CAN TAKE UP TO 6 WEEKS FOR RESULTS SO PLEASE MAKE SURE YOU HAVE THIS
DONE IN PLENTY OF TIME BEFORE YOUR PLANNED MATING.
2. HC
– HEREDITARY CATARACTS.

3. PHPV
– PERSITENT HYPERPLASTIC PRIMARY VITREOUS
4. PPSC
– POSTERIOR POLAR SUBCAPSULAR CATARACT.
It usually remains as a small, punctuate cataract and doesn’t
usually lead to sight problems in these two breeds. It has been placed
on schedule 3 of the BVA/KC/ISDS Eye Scheme because a number of Staffords
that have been through the Scheme have been found to have this type
of cataract. This type of cataract cannot be detected through litter
screening. The mode of inheritance is unknown and has a variable age
of onset. BREEDING STOCK SHOULD BE TESTED ANNUALLY TO DETERMINE
THAT THE DOG IS CERTIFIED CLEAR AT THE TIME OF MATING.
Eye
Testing Clinics
The other test required is phpv eye testing,
This needs to be done by an eye specialist
We found it hard to find out where to get this testing done

We have had many emails asking us what makes a suitable stud dog?What health testing is needed when studding a stafford? Are there any changes to the stud dogs character or temperament ? General advise on handling your stud while mating, we hope the following points answer the most commom question asked about studding your dog.
We can answer from our own view point and share the things we have done , we are not experts ,each dog is different,but we will list the route we have followed.
Levi is our first stud dog,we had used an outside stud until we decided we would like to breed the blue stafford,We like the boys but our last male was castrated at a young age to avoid unwanted litters.
We looked around for a blue stud in our area,as we were looking to get our first blue bitch,we found there were not many good blue stafford examples available for stud,so we decided we need our own,its very hard to choose a pup
that you are hoping will grow into a good example of the breed and make a suitable stud dog,we looked at many blue litters and found many were being breed just for colour,the parents were not good examples in our eyes.
we wanted to see both parents,when selecting a pup, we found this almost imposible!
we knew what we were looking for but just couldnt find it
So if we brought a male that was not a good example,we decided not to get a bitch to forfil our dreams of breeding the blue stafford,he would be just a pet,at this point we decided to take a chance .
We found a litter 9 weeks old, with 3 boys to choose from ,the colour was the strongest blue we had seen,both parents were the best we had seen ,there was one pup that stood out from the rest, but the owner wanted him, we were about to walk away,when they changed their mind and agreed to sell Levi to us.
He was a funny looking little pup ,with one puppy ear that flopped forward,we just hoped he would be the start of blue stafford,there was some very good examples in his pedigree,
Ch valgo lancer, Ch lethal weapon of crashkon(twice), ch valgo corolla CH debrella scotch on the rocks of dumbriton, Ch maradin master mariner, ch fulfin black eagle(twice) ,CH lawbury spikerjoe, but only time would tell
See pictures of Levi as he grew on the gallery page by the age of ten months we could see he was every thing we were hoping for
We entered him into a puppy class at a stafford show ,he came third out of twenty five ,this was very pleasing to us ,we loved him but it's nice to get an experts opionion
We had him independently looked at by a cruffs judge ,she checked his teeth and movement ,the results were that he was a good repersentive of the breed meeting the breed standard
So we have a blue stafford suitable as a stud ?
The next hurdle was health testing L2/GHA & HC this is done by a blood sample taken by the vet and sent to the animal health trust (down load the forms required on our matting tips page)
Both tests came back clear,The tests results needed to be photo copied and sent to

The other test required is phpv eye testing,
This needs to be done by an eye specialist
We found it hard to find out where to get this testing done details of the people we found are on this page
so we now have a fully health checked dog suitable as a stud as
Levi holds a current eye certificate Phpv
Another big consideration is temprement Levi is good with other dogs and children (in answer to the question is my dog suitable for stud ,we would answer , has the dog had health testing ? is the temprament good ? is your dog a good reperasentive of the breed that meets the breed standards?)
Levi sired his first litter to Magic when he was a year old
We had a problem getting Levi to mate to strange bitch's to begin with he didnt like strange dogs in our garden
We asked advise from other breeders ,we have found a routine that has been very sucessful
Are routine is we meet the bitch and owner outside on the road ,we walk the dogs together on lead for a short distance
This lets the dogs get used to each other,if the bitch is ready and giving off the right smell, as soon as we get into our front garden Levi will mount the bitch as soon as he can!
The dogs stay on lead and a tie is very quickly acheived ,Levi is not an over sexed dog if the bitch isn't ovulating he is not interested
every mating so far has produced a litter,the mating takes place calmly and quickly ,we use the holding method and have found this our prefered method
What is the holding method?
The owner of the bitch holds the bitch by her collar while levi mounts her and soon as possible we turn the dogs, some bitches after a tie will try to get away ,both dogs are held in place, so no injury to either dogs occur

Levi is very laid back,and remains very still when tied to a bitch, its normally a bitch that needs holding still

Levi needs a sleep after work ,he has a smile on his face!

This next section is to answer some questions we have been asked
(Q)I think my dog needs to be used as a stud because he mounts my friends, shaggs my cushions if we use him for stud work will this stop?
(A)Mounting is a dominace problem , teach your dog this is not exceptable behavior! If your dog is over sexed get it castrated
(Q)If we use our dog for stud will this change his charatcter or temperament and show sexual interest in all dogs as a result?
(A)A dog that is used as a stud will only show interest in a bitch in season no changes in the personality other than more laid back and content, we have found living with a stud dog no different than living with any other male dog .
(Q)Does studding your dog cause agression problems?
(A)The only time this could be a problem is if two males were in the same place as a bitch in heat.
(Q)Will my dog mark my home when used as a stud?
(A)Levi will mark much more out side when a bitch is in heat but he has not done it inside.
(Q)At what age does a male become sexually mature?
(A)Even a young pup of 5/6 months should be kept away from a bitch in heat to avoid an unplanned litter,we found with Levi he really got the hang of things at around 18mnths .
(Q)If my dog is castrated will he no longer show interest in my bitch when she is in heat?
(A)My 11 year old castrated bulldog, shows more interest in my bitches in heat than Levi our stud,he mounts and is still very intersted.
Our first male was castrated at 6mnths old ,he still managed to tie with his mother! so we would defently say the only real difference is it stops unwanted litters .
(Q)I dont think my dog will make a good stud as he has never shown any interest in mounting or show any sexual interest in bitch's.
(A)When a bitch is ovulating and ready to except a dog its the smell that attracts the dog ,This triggers the sexual behavior
(Q)we have tried to mate my bitch on her first mating with a dog that had never mated before,with no luck.
(A)Its best if one or the other has mated before,then at least one or the other knows what to do!
(Q)Is there a risk of injury when mating my dog?
(A)When mating two staffords if the bitch is a madien or isn't quite ready she may well be agressive, an untrainned stud could retaliate and a fight could break out! Or if the dogs are runnung free while mating
there is a risk to both getting injured if the bitch tries to get free after a tie has taken place! by using the holding method/ & using a soft muzzle on the bitch this can be avoided
not all studs will mate on lead a dog needs to be trainned to do it,we feel it is well worth the effort
(Q)Is it eaiser to own your own stud dog
(A)When you need a stud it is convient , however when a bitch is in heat and you do not wish for a litter it is very difficult to be sure they are kept apart
(Q)How can I be sure a stud dog has had the testing for L2/GHA / HC & phpv eye testing has been done
(A)The kennel club has a web site if you know the kc name of the dog you can check your self on line
The kc will have recived photo copys of the test results and cheked that they are geniune
