Dog got rattle snake bit

I dont know what to tell you that far along . But as soon as the dog gets bit you need to fill him full of antibotics and also give 3 cc of Dext. The Dext will keep the fluid off his lungs and keep him out of shock . I would give it to him several days in a row along with the antibotics injections. Just got to keep them full of it for a few days to a week are so . Lots of people say give them benydril but that only works right at frist if you have noting else when I say at first I mean the first few hours then it dont matter how much you give them not gonna help much at all . I had a dog get bit three times chest, underneath and in the side . I did just what I just said and saved her . Called the vet and he said that would have been all he could have done also .
