If your dog ever gets lethargic suddenly, starts going limp, and starts to feel cold - take him to the vet right away. I doubt they could have saved my dog, but maybe they could save yours. Just, take it to the emergency vet. Even if its a 30 minute drive at 90mph to the nearest one, take them there. Please.

I have a Samoyed that was bitten by a rattlesnake last year. I rushed it to the vet and they were able to save my dog. I wasn't sure what was wrong with it at the time and only found out about the snake bite afterwards. Yes, don't hesitate to take your pet to the vet if they are acting strangely. Can save their lives
