What is the name of this movie

Alright, I need everyone’s help 😂 I watched a movie when I was younger with rattlesnakes in it. There was two scenes I can remember of the whole movie but I cannot for the life of me remember the name and google is no help! One scene is where a man bends down to pick up something he dropped under his truck and the snake bites his hand. The other scene is an old man’s dog got bit and he doesn’t know but he loads him up in his truck and the dog licks him in the face and he ends up getting sick and passes away just from the dog licking him. Does anyone happen to know what movie this is? It’s not silent predators I just watched that and that’s not it
