If you scroll up, I also supplied that information in the previoius post concerning general information. Normally symptoms start to appear between 1-4 hours after ingestion. If you don't see those symptoms within that period of time, then it is likely he is fine from the theobromine. The fat content leading to pancreatitis would normally develop in the next 24 hours. So monitor him for the next day or so. If vomits more than just a couple of time then I might have him seen for pancreatitis. Just in case you didn't read the first post I'll copy it here.
My name is ***** ***** I’ve been involved professionally with dogs in the health and behavioral fields for over 18 years. It will be my pleasure to work with you today.
in order to get you a quick answer since time can be an issue, I'm going to send you the prewritten instructions I have to give clients concerning chocolate ingestion. Then I'll address the amount directly in the next post.
First thing is to not panic. Different kinds of chocolates have different toxicity amounts. Chocolate contains theobromine, which is what causes the toxic response. If the dog ate the chocolate recently (within last 2 hours), you can induce vomiting with 1 teaspoon of hydrogen peroxide 3% per 10 pounds, which can be repeated 10 minutes later if it does not induce vomiting. Items such as cookies and cakes will have less actual chocolate in them, so you will have to make an estimate in the amount of chocolate that may have been in the amount of cake, brownie, or cookie your dog may have ingested .
Signs of theobromine toxic poisoning should appear within 1 to 4 hours of ingesting the chocolate. These include vomiting, increased thirst, diarrhea, weakness, difficulty keeping balance, hyperexcitability, muscle spasm, seizures, coma and potentially death from an abnormal heart rhythm.
The following websites will give you’re the approximate amounts of chocolate that you will need to worry about based on the size of your dog and the type of chocolate. Consult this page to determine if a toxic amount has been ingested.
There is also an interactive chart available as well here:
If your dog has ingested enough to be toxic according to the chart, you need to have your dog taken to the vet for supportive care. Your vet can administer charcoal to absorb the toxins and let it pass through your dog’s system with less absorption and monitor your dog’s vital signs until the danger has passed.
You also should be aware of the fact that the high fat content in chocolate can also trigger pancreatitis in some dogs and you may wish to take your dog into the vet to avoid this condition developing and definitely keep an eye out for symptoms of this.. You can read about pancreatitis here:
