Here's what you should do:
1. Keep your dog calm and still. Movement can increase the spread of venom.
2. Note the time of the bite. This is important information for the veterinarian.
3. If possible, try to identify the type of snake. Take a photo if you can, but do not put yourself in danger.
4. Transport your dog to a veterinarian as quickly as possible.
5. Follow any instructions given by your veterinarian.
Do not:
* Attempt to suck out the venom. This can actually increase the risk of infection.
* Apply a tourniquet. This can cut off circulation and damage tissue.
* Give your dog any medication. Only administer medication as directed by your veterinarian.
Remember: Time is critical in snakebites. Immediate veterinary care is essential for your dog's survival.
