It is a shame about the ataxia, Frosha I believe was diagnosed later in life, and most show lines were bred into that blood, There are 3 main dogs gr ch's who carried ataxia, unfortunately they were bred heavily before they were diagnosed... Most ever AST alive today has at least one of the three in their ped.
Day blindness is another one, sorry cannot pull the med term off the top of my head....
kinked tails, heart issues are also on the top of the list...
patellas, hips, god there is a long list.
Now APBT's do also have to worry about those things, but there are still lines which are not affected by them
It's not so much that I feel the dogs are different breeds, I just feel that because of the way they were bred, the AST and the APBT do not have the same percentages of problems on their health issues... Now you can test for Ataxia, but you cannot test for Day blindness yet... and the heart and joint issues I hear about from long time breeders of some ch and grch AST's admittedly say the AM staff's are ruined.
Lower mandible degeneration is prevelent, c'mon, how can you even begin to intigrate an animal with not enough bone structure to NOT break their jaw playing with a bone???? Are they all like that? I doubt it, but it is an evergrowing problem.
Do I know it to be a fact, that there is not enough of a healthy gene pool in AST's to recover, No I do not, but I most certainly would investigate very closely before I would add that blood to my yard.
There are just way too many health issues, and breeders all know someone who has them, but surprisingly every breeder you talk to does not have those problems themselves... Very few will be truthful, so I would be careful. If you breed for pretty, you will inevitably loose in the long run.
