Re: Crating while at work?
Yes, 9.5 hours is too long, even for a well-excercised, adult vizsla (and I imagine almost any other breed too). But fear not! I know lots of people on the forum can give you ideas about how to manage the work-week, but there are many ways it could be done. For example, if either of you can get home mid-day for a 30-45 min walk/fetch/off-leash romp, that might get you through to the weekend. Or, find a doggie daycare that you're comfortable with --- half day or whole day would get you through also. Or, hire a dog walker you trust. I think what the websites you've been reading are trying to get across is just that a vizsla has neither the independent streak or the energy level to ever be okay being left alone for long periods of time (more than a few hours or so). When you bring yours home, you'll see exactly what they mean.
That being said, you'll find that puppyhood schedules are very different from adult schedules. When my pup (now 7 months) first came home at 8 weeks, I was amazed that she had the schedule of an infant! She'd sleep for an hour, play hard for an hour, then sleep for an hour, then play hard for an hour and so on, with lots of peeing in between. And puppies have to pee all the freaking time -- that's why most people follow the conventional 1-hour of crate time per age in months plus 1. And utilize crate dividers during that time.
But now, if I can get Lua to go on a good off-leash run/walk/hike for a couple hours, she'll be just find in her crate for about 4 hours (I've never left her in longer than that, as I have a flexible grad student schedule). Other things that tucker her out are doggie daycare for a half-day, going to the dog park for 1-2 hours, having a playdate with another V for a couple hours, or playing lots of tug, fetch, and doing some training games. And her best dog-friend Nemi (nearly 2 y.o.) will sleep all day after a good bout of activity. So your strategies will change over time --- just be prepared to get creative
