Is this going to hurt her?

Is this something that could be genetic? I mean could her parents passed it off to her, the people we got her from had been breeding yellow labs for 8 years, problem free! or is it just every so often dogs have this happen? Im worried...i mean com'on how likely out of 10 or 11 pups that we just happen to grab the one that has health issues that cost us hundreds? haha, thats just the luck huh!
Edit: Im kinda curious as to why they just cant give us medicine to clear up whatever she has? I know this is to help her inflamation but it's not making it go away, there has to be something to just cure it!!
Out of all the dogs in the world, i can not be the only owner who has had this problem!!!

Another question...What do you think about maybe a Protein suppliment? Like a vitamin sorta...that she can take instead of taking meds. If a protein deficiency was the problem, maybe a suppliment would be better for her?
