If it makes you feel any better, I'd reckon that you'd have time to get your dog to the vet if one got bitten by a rattlesnake. Snake bites are really variable. The most common snake in my part of the world is the Eastern Brown, which is the second most deadly land snake on Earth. To make it worse, they are nervy and unpredictable. Supposedly, a brown snake bite can kill an adult human in 30 minutes. However, in practice, I've heard of a lot of cases where people have been bitten and not got medical treatment for several hours. And I know of dogs that have been bitten and have not been treated until an hour or more after getting bitten and still come through, a couple of thousand dollars and a week in hospital later. From what I know of rattlesnakes, the venom is not a neurotoxin like that of Australian snakes, and it works by breaking down tissue. So it looks revolting and terrible, but it's not as dangerous as a strong neurotoxin, which stops the animal from breathing. As far as I know, it doesn't work as quickly as a strong neurotoxin, either.
Also, a snake can bite and not envenomate. That means your dog can get chomped on, but not poisoned. Some species hardly ever envenomate, some do a good job of it. Over here, the brown snakes often bite so fast they don't deliver a lot of venom. Their strategy is to hit fast, then let go and stay clear. They have incredibly effective venom and don't need to deliver a large dose. On the other hand, tiger snakes take a bit more provocation to bite, but when they do they often give you enough venom to require 5 vials of antivenom.
Finally, you'd be surprised how slow a snake can be if they haven't been sitting in the sun for the last few hours. You can judge how warm a rattlesnake is by how fast it rattles. If you have the presence of mind.
I have seen snakes striking repeatedly at dogs and the dogs cheerfully dancing out of the way. Even the time I saw my mother's dog riling up a tiger snake that we found sunning itself, the snake reared up and tried to strike but missed the dog. I got him away by running away from him. The snake was very peeved.
When it comes down to it, my advice is the more you know about the snakes in your area the better. As a zoologist in a country full of very poisonous snakes, knowlege is power. Know your snakes, know how to treat a bite. I keep an elastic bandage on me for treating snake bites whenever I go into the field, no matter the season. I know to avoid turning over rocks or logs (unless I'm actually looking for snakes). Over here, though, spring is when you see the snakes, and you see them out on paths sunning themselves. If given a chance, they usually get out of your way. I have been known to stamp my way through likely snake spots. I'm also blessed with a dog inherently nervous about snakes. She won't go near them. You're lucky your snakes give you warning!
Oh, and incidentally, I've only seen one wild rattlesnake, and it was VERY warm. When it rattled, it sounded more like an extremely loud insect buzz than a rattle. You can bet I let that one alone, even though I'm hopelessly curious about snakes and always go oggling them and such. Wish I had such a good way to judge how warm and cross our snakes were.
