Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Chocolate chips in cookie dough are usually semi-sweet which has a moderate amount of cocoa. As cocoa contains compounds known as meyhylxanthines such as caffeine and theobromine, they can cause hyperexcitability, elevated heart rate, vomiting, diarrhea, tremorring, seizing, and even death. The good news is, these signs are dose-dependent, and it sounds like Riley has likely ingested a low dose for his weight. You can check out the chocolate toxicity calculator at petmd.com/dog/chocolate-toxicity. It is always safest to have a vet examine and discuss induction of vomiting, but Riley is unlikely to have any major issues from this amount of chocolate. Other things to worry about would be if he ate any plastic, other foods, raw foods, or spoiled foods as these could cause illness as well. Watch for lethargy, vomiting, inappetence, diarrhea, tremorring, and abnormal behavior in addition to the signs of chocolate toxicity. Have him seen immediately if you notice anything described above. Hope this helps!
