Sorry to hijack this thread. Staffordshire Bull Terriers have got the nickname 'the nanny dog' because they are usually so good with children.
Fortunately, there is now no need for any Staff to ever be born with Hereditary Cataracts again, because there is a DNA test which the parents can have before being bred from. This will determine whether the dog/bitch is a carrier of the condition, affected or clear of it. Anyone buying a Staff puppy should make sure the parents are tested.
There is also a test for Staffs for L2-HGA which is an auto immune disease. Again parents should be tested before being bred from to prevent suffering in puppies.
Current figures for testing show that for the L2-HGA test there have been 1808 dogs tested as normal, 261 carriers and 18 affected. For HC there are 1151 normal, 52 carriers and 0 affected. (The L2-HGA test was available about six months before the HC one.)
This gives puppy buyers a good choice of puppies from tested parents, and information on responsible breeders who do the tests can be obtained from any of the 18 breed clubs spread throughout the UK.
