We had someone call in to our clinic just this week with the same question, but we had to look it up. They can be toxic if the raw meat is ingested, but it's more of a GI upset thing (vomiting, diarrhea) than affecting organs. They generally taste very bitter, so a dog is unlikely to actually eat it. The other thing to worry about is if they're eaten whole is causing a blockage. You'll see vomiting and some diarrhea with that one, but they act very sick and painful in the abdomen, and will need emergency surgery.
So it would be a good idea to try to keep her from eating them, but if she's a larger dog and happens to swallow one, no need to freak out.![]()
