Coco was given half a slice of garlic butter cheese by my kids. She threw up and is lethargic.
I'm really sorry to hear that Coco isn't feeling well. Garlic can indeed be toxic to dogs, and even a small amount can cause gastrointestinal upset, which might explain why she's been vomiting and seems lethargic.
For now, it's important to ensure Coco has access to fresh water to keep her hydrated. However, it's best to avoid giving her any food until her stomach has had a chance to settle. Keep a close eye on her for any additional symptoms, such as diarrhea, pale gums, or an increased heart rate, as these could indicate a more severe reaction.
Given the potential toxicity of garlic and Coco's current symptoms, I strongly recommend taking her to a veterinarian as soon as possible. They will be able to provide the necessary treatment to help her recover and ensure there are no further complications.
If you have any further questions or need additional assistance, please don't hesitate to reach out. Thank you.
