The amount of chocolate he ate in those cookies and the size he is makes me feel that he's probably going to be fine. The amount of chocolate and the darkness of it are the main factors, along with the size of your dog in determining if he will have adverse effects. Monitor him for vomiting, diarrhea, seizures, muscle rigidity, rapid breathing without exertion, or increased body temperature. If he displays ony of these symptoms, get him to a vet right away.

    I'm glad to hear that Charlie is acting normally - I'm sure she enjoyed her unintentional treat! By 4-5 oz., I'm assuming that you're including the total volume of all 3 cookies rather than just the chocolate volume of any semi-sweet chocolate. With this in mind, I'm assuming that at most she would have consumed 1 tablespoon of cocoa powder and 1 oz. of semi-sweet chocolate chips. If this is the case, I wouldn't expect any issues unless she has a sensitive stomach. In this case, she might experience some vomiting and/or diarrhea. I know that I'm making some assumptions here, but even if she were to consume a full 4-5 oz. of semi-sweet chocolate chips, I would only expect to see some vomiting and diarrhea. Given her size, she would need to eat a good bit of chocolate chips in order to experience the more severe aspects of chocolate toxicity, such as heart arrhythmias and/or seizures. As long as Charlie continues to eat, drink, and act normally, I wouldn't worry at all. However, if anything changes with respect to vomiting, diarrhea, lethargy, breathing changes, or seizures, be sure to seek veterinary care right away. I hope this helps and that everything goes well!

    Two cookies will likely result in nothing worse than some vomiting or diarrhea. The risk of a serious chocolate toxicity is low. Arya would need to eat 6 or more ounces of semi sweet chocolate chips in order to be at moderate or severe risk of toxicity. If necessary, withhold food for 24 hours, then feed a bland diet in small, frequent amounts until any vomiting or diarrhea resolves. Transition slowly to the regular diet afterwards.

    A dog of Bennett's weight would need to eat more than 5 ounces of milk chocolate before to result in a serious risk of toxicity. A large chocolate chip cookie may result in some minor gastrointestinal upset. You may see vomiting, diarrhea or a decrease in appetite. This can usually be managed at home with a 24 hour fast followed by a bland diet fed in small, frequent amounts until symptoms resolve. Monitor for tremors, hyperactivity, increased heart rate, ataxia (wobbly gait). Or seizures. These are all symptoms that should be addressed by your veterinarian immediately.
