This link to the Stickey in the Health library should answer a lot of your questions.
Timing is variable per condition and the severity of the condition:
Leggs Perthes 7+-12 months old
HD - if mild can go undecteted for years. More severe grades of HD will probably start to show themselves at 1yr+
ED - same as above
LP - you can tell as early as eight wks old, if the patella clicks. Some pups as they mature can right themselves from what is called loose knees - but by 3mths old you can tell more.
PRA and or cataracts - can be evidenced as early as 6mths to a year, and some not until 5-6 yrs old.
LS - Bat testing can give you an idea of the health of their liver - do at 16 wks old and repeat at 6mths old. In severe cases onset of symptoms can be as early as 4mths old or as late as 4-5 yrs old in very mild cases.
AAI - is pretty variable. Depends on the severity. Often times can go un-diagnosed for several years.
Please note there are no Genetic tests for these diseases. Health screenings prior to breeding is the most a breeder can do. \\
