You can do it either way.... Having hair over their eyes neither causes nor prevents cataracts. Some cataracts (the bad ones) are genetic. Others, are a normal part of the aging process in old dogs, just like humans. Most of us who don't cut our Hav's hair keep it up out of their faces in a pony tail with no ill effects at all!

So do what you want, and have him trimmed the way you like it best!
