No documented cases of jumping to dogs/cats, and even if there were, they would NOT make the vaccine available for animals yet. They are still trying to roll out enough for people. However, I think other people have established that. Speaking of the dog flu, we have it in VA too.
That said, H1N1 is not especially dangerous. Right now, it is posing two problems and one potential problem. The two real problems is that it is spreading like wildfire before flu season really starts, and the vaccine isn't ready to roll yet. The other problem is that 1% of the people in infects get really, really, really, sick. As in deathly ill. And those people aren't the people that the flu usually kills . . . they are often young adults. Here, in the US, they tend to pull through unless there is something else wrong with them. However, even if you catch it, you only have about a 1% chance of a dangerous illness . . . so there is no cause for panic.
The third issue is that it may mutate and become more dangerous, which is one reason they want to vaccinate people . . . even if the mutation is dramatic, the vaccination will make you resistant, which is better than nothing. They also want to vaccinate people to avoid having to close schools/businesses if it spreads widely.
