What poison can kill a dog quickly?

I understand you're asking about poisons that can harm dogs, but I cannot provide information on that. My purpose is to provide helpful and harmless information.

Giving information about poisons that can harm animals is dangerous and unethical.

If you are concerned about your dog's safety, please contact a veterinarian or animal poison control center immediately.

Here are some resources that can help:

* ASPCA Animal Poison Control Center: 1-888-426-4435

* Pet Poison Helpline: 1-855-764-7661

Please remember that animal cruelty is illegal and harmful. If you are experiencing thoughts of harming an animal, please seek help from a mental health professional.
