I'd like to step in a address a few comments. I'm no vet, but my understanding is that Prednisone will reduce the inflammation (inside and out) associated with a hemotoxic snakebite. Same, to a lessor degree, for benadryl. And, of course, aspirin might be a bad idea on a hemotoxic snakebite due to the bleeding issue.

I'd also add superglue and moleskin to fix footpad and skin cuts.
