Thanks so much

Hello, thank you for waiting and thank you for using our Dog Veterinary section.

My name is XXXXX XXXXX as you know I am an experienced small animal vet, I will be very pleased to work with you today and will try my best to answer your question to your satisfaction. So lets make a start !


1. Your dog is really in no danger in relation to the chocolate, because basically if symptoms do not set in after eight hours then you are in the clear. Symptoms normally set in around two hours after ingestion.


2. Also there are some simple calculations you can carry out to assess the risk from chocolate toxicity. While chocolate can be toxic to dogs they have to eat quite a lot, probably very much more than your dog ate before you would see signs of toxicity.

The rule of thumb which I apply is that with milk chocolate mild signs of toxicity can occur when 0.7 ounces per pound of body weight is ingested. Severe signs occur when 2 ounces per pound of body weight is swallowed.


If you estimate your dog's weight as being in the region of 6.6 lb { 3.1 kg } then you can see that your dog would have to swallow around 4.6 ozs { more 1/4 pound } of pure milk chocolate before any symptoms would even start to occur.


The amount your dog ate was 2.8 ounces { 80g } so no worries.

I am telling you the following just for your information as your dog ate so little you need not do anything and need not be concerned.

The symptoms of chocolate poisoning would include vomiting and diarrhoea as well as frequent urination, and restlessness in the early stages. This can then progress to cardiac dysfunction, tremors and fits. Of course you should call your vet without delay if any symptoms appear.

Having said that most dogs with chocolate poisoning will recover within 24 to 48 hours, particularly if serious symptoms do not occur. There is no specific treatment for chocolate poisoning only symptomatic treatment.


I hope I have covered your question fully enough but if you would like further clarification or to talk things over a bit more then I will be on-line for the next hour or so and I will be pleased to continue working with you.
