good
When a clear thought strongly and immediately pops into the mind upon reading a name, you know you have something of at least some value. Definitely 'vertical portal' on pet-training flashed into my head loud and clear, despite the other myriad possibilities. I notice you have it parked at Sedo with random ppc on it, but with a name like this I think the magic is in giving the consumer what they immediately think upon reading this name... some specific links on pet training. Maybe do a little testing on Sedo, try optimize the name for that purpose, and see if your 'clicks' increase substantially?
Short, snappy, memorable, common saying, and infers something that people will be looking for (animal training), so I'd say easily reseller high-xx to low-xxx. But seems perfect for interest-group traffic, I'd say definitely develop even a little as a portal and then at least med to high - xxx. More if you can really optimize the site's visibility and subsequent increased traffic.
I like it, good nab.
As for your other uses, here's a few related names that are still available, and mean exactly the opposite of your name, ha:
