Literally seconds ! There was a recent documentary on cable TV by David Attenborough - where a rattlensake bit a mouse that wandered too close. The mouse twitched a couple of times and was dead - my estimate was about 2.5 seconds !
Many factors need to be taken into account: age, weight, area bitten, how much venom was injected. what immediate first aid was given, has the person ever been bitten before. It only takes a few hours without anti-venom injections.
I don’t know
People used to suck out the venom through the bite. This wasn't always effective though. They could never get all the venom out. The venom would usually spread through the body not long afterwards.
If a rattlesnake totally exhausts its venom supply it will take several weeks to fill its venom sacs again. This is why rattlesnakes do not want to use their venom in defense as it may leave them with an insufficient supply for obtaining food.
It depends on how much venom was used in the bite. Snake venom takes time to replace, and they only use enough venom to subdue their prey. Replenishing can take anywhere from a few minutes to a day.
they are born with it
it will take five minnset
If your dog has been bitten by a rattlesnake and the area around the bite is all swollen, please take him to your Veterinarian. Ask if you can make payments. This does need to be treated with anti venom plus antibiotics and steroids. Only a Vet knows the proper dosage.

It will, on average, take her 10 to 15 minutes to have them.
Generally , depending on the size of the actual snake , and the amount of venom it secretes into your bloodstream , anywhere from 1-2 hours . If the victim is very young or old/sick , death can occur within 30 minutes . Most snake bites are dry bites , meaning they do not inject venom when they strike . But without proper medical attention , the hemotixic venom will break down tissue and you could actually bleed to death internally from the anti-coagulant properties of Rattlesnake venom .
