Here are some things to keep in mind:
* Fire logs can be toxic. They contain chemicals that can cause serious health problems in dogs, such as vomiting, diarrhea, and even death.
* The longer you wait, the more dangerous it is. The sooner you get your dog to a veterinarian, the better the chance of a full recovery.
Please take your dog to a veterinarian or call an animal poison control center immediately. They will be able to provide the best advice for your specific situation.
Remember: I'm just an AI, and I can't give medical advice. The safety of your dog is paramount. Please act quickly and seek professional help.
