Cough drops often contain ingredients that can be harmful to dogs, such as:
* Menthol: Can cause respiratory distress, vomiting, and diarrhea.
* Eucalyptus oil: Can be toxic to dogs, causing gastrointestinal upset, liver damage, and even death.
* Artificial sweeteners (xylitol): Extremely dangerous for dogs, causing liver failure and death.
Even a small amount of cough drops can be dangerous for your dog. If you're concerned, please call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately.
