Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. While ingesting chocolate can be very dangerous to dogs, this small amount of likely milk chocolate will probably be fine. Brownie may experience some GI upset such as vomiting or diarrhea. Signs of chocolate toxicity include vomiting, hyperactivity, elevated heart rate, to more severe signs such as arrhythmias and even seizures. That being said, Brownie should be fine with that small amount of chocolate ingestion. I hope this is helpful!

    Thanks for using Petco Pet Education Center, formerly Petcoach! This is concerning as it appears that Roxey is a small dog. However, how likely she is to develop a severe reaction depends on the exact amount of chocolate ingested which varies per package. The amount of chocolate would be in the bag and that information would be quite helpful in order to know how serious this can be. Having said that, it would be indicated to have Roxey evaluated by a veterinarian as soon as possible to check the amount of chocolate ingested but also to check Roxey for manifestations of chocolate toxicity and treat accordingly. Chocolate toxicity can result in gastrointestinal signs, heart issues and even neurological signs such as seizures. If this just happened, a veterinarian would be able to possibly induce vomiting to try to retrieve some of the chocolate. Good luck!
