pruning rose bush

I'd like to prune my one rose bush way back. Is that OK? Like half way? More?

Do you know what kind of rose is it? Most will be fine, there are a few exceptions, but for the most part they respond well to pruning.

Thanks cocoa. No, I have no idea what kind it is, so I'm just going to go for it--make it the size I want, and we'll see..........

If it only blooms in spring, wait until after the spring flush, But not a lot of people have those. I'll bet you make happy with a good pruning :0) just follow with a good fertilizing
