Cholesterol does not have anything to do with cataracts as far as I know... it's important instead to maintain the membrane stability of cells. Although it is important to keep your cholesterol level low, it is also important not to keep it TOO low.
Too much cholesterol, which integrates itself into the cellular membrane, aids in making the membrane more soluble and it allows more molecules - in particular ions - (good and bad) to come into your cells - this is bad because each cell in your body is made such that they have the correct amount of ions and other molecules to survive and/or proliferate. However, when you have too little cholesterol, the opposite happens and things that SHOULD be getting into the cell cannot and it changes the composition of the cell, which can seriously damage it. This can happen in all cells. Cholesterol is also an important protein modifier that allows for the uptake and diffusion of signals to cells (this tells cells what they should or should not be doing at a specific time point).
There's a lot of confusion about the importance of cholesterol since everyone just thinks that cholesterol is bad since nowadays everyone talks about how you shouldn't have any cholesterol. This is incorrect. You shouldn't have too much cholesterol (there's also bad and good cholesterol but I won't go into all of that). Having absolutely no cholesterol is actually a very bad thing and can lead to serious defects.
Sorry for the long explanation, but I hope it makes sense. I'm not basing this off of any dog article, mind you, only on my own knowledge (I'm a biochemist).
There is research out there that says that Havanese do not produce enough cholesterol for themselves and as such they need to be given that supplemental cholesterol in their diet.
