Ask a Dog Vet and Get Answers to Your Dog Health Questions
Hello, I'm Dr. Deb.
The expert you requested isn't currently online but given the nature of your question, I can help if you'd like.
Some of the gel packs contain iron which if ingested in large quantities might cause some issues but if only a small amount was eaten, then this shouldn't be a concern.
I wouldn't expect any significant toxicity for your dog although diarrhea might develop in 12-24 hours. A bland diet of boiled chicken and rice should resolve the problem within a day or so.
I hope this helps to reassure you that your dog should be fine. Deb
