Rattlesnake bites rarely kill when properly treated. Rattlesnakes almost always give a warning before striking. I used to hunt them and they are fairly slow and given half the chance and a bit of space would rather just slither off. If untreated a bite can indeed cause tissue damage. My grandparent's dog got a big bite from a massive rattler and had to spend the night at the vet's office after a shot of antivenom.

The dog jumped over a rock, I heard the warning and assumed the rattler didn't strike. Wrong. We continued the hike and thirty minutes later noticed the big lab kept sitting down. Then it started laying down even when we were on our way back. He refused to continue and I ended up carrying the heavy beast a quarter mile to the house where I did a careful examination.

I found a nice sized puncture in his neck but couldn't find the other puncture and assumed it was a strike that almost missed. I found the other puncture below the first one and much further away than I expected. A very big rattler indeed.

Post treatment the dog was back to normal activity in three days with swelling and redness around bite. A week later swelling was gone and site was scabbed over punctures with minimal tissue damage. A month later all evidence of bite completely completely healed.

Edit: I should add that the trip to town was about 45 minutes. So including time post attack spent hiking before treatment was about 2 hours.

Dog showed signs of obvious discomfort at the vets as it would get up, walk around a bit then flop down, heavily sigh, lay it's head down, then get up and move to other side of the room as vet and I spent a few minutes observing the poor dogs behavior. Total cost of treatment including the night at the clinic was $1,000.00. Grandma debated letting nature take it's course due to expense but I argued Grandpa was very fond of the dog as a companion. Grandpa was getting weaker every month and the trauma of losing hid buddy so late in his life would depress him.

Grandpa died two years later in his own home with an in home nurse attending him. The dog rarely left his side except to eat or go outside to relieve himself. When Grandpa died the dog refused to allow the nurse to check his vitals, stood in her way and kept moving to block her until he had to be dragged away and held back. Good call on giving the dog proper treatment for his bite.

no, but unless you act quick and have someone with you you are likely to die.

australian snakes have shorter fangs. the venom goes into the lymphatic system which gives you a head start. you start moving around that limb the venom pumps through the system, if it gets to lymph nodes it gets into the blood then youre fuckoed bucko.
