But will they still be rattlesnakes then if they don't rattle? XD

Thankfully where I live there aren't too many venomous snakes (mainly just rattlesnakes) and they're not super frequent. This was my only actual spotting of one in the wild and I've lived here all (almost) 30 years of my life.
Those doggos are lucky to have such an attentive person caring for them! Hopefully the one that was bitten recovered well.

Also, snake pics have been added to first post.
