Any eye problems, such as excessive PPM, cataracts, coloboma's.. which will all show up on the CERF report. And it is just as important, especially with PRA to have a "family history" since it is late onset with no DNA test yet. Fanconi, Thyroid, Patellas, hips/elbow (usually done at the same time), are really the ones you want to make sure are done if looking at a pup.. (at least IMO). Heart is good to have, but not a huge thing is not done.. unless there happened to be a family history of possible problems. (has not been a problem in Basenjis over the years).
One of the biggest and best things you can look at is the age of pup's parents, grand parents, great grand parents and what is their age, how long did they live, what age did they die?…
My personal opinion is that I want to see dogs that are not being bred from babies... I don't like to see 3 generations that the oldest dog is only 6yrs old as great grand parents.. there is no way to really build a health pedigree based on very young dogs. When I bred Mickii, the sire of her pups was 14yrs old... and he live two years past that...
Kobey's Mom was 6 1/2 when he was born, as was his sire. The grand parents were 9, 10, 11, and 8 and the Great Grand Parents were 10,14,15,10,15,11,17 and 12 (all but one of the Great Grand Parents were still living, the 17yrs old had passed at 15)
