As I'm sure you are aware, caffeine is toxic to dogs. Symptoms can occur with the consumption of 9 mg/pound of caffeine. At Riley's weight, that would be 306mg of caffeine. She should be ok, but monitor her for the next 24 hours to be safe. Best of luck.

    A lethal dose of caffeine is considered to be around 70 mg per 1 lb body weight (150 mg / kg body weight), but severe symptom can occur with much less than that. if you are unsure of the dose ingested please contact the http://www.petpoisonhelpline.com

I just spilled my venti latte with an extra espresso shot onto the bed and Cassidy drank a significant amount of it before I was able to get it cleaned up. How much coffee is toxic to dogs? Should I take him to emergency?
Oh no, that's not good! Symptoms can occur with the consumption of 9 mg/pound of caffeine. I don't know how much Cassidy ingested, but you may see signs. I'd take him into the emergency vet now to be safe. Best of luck.

My dog ate A half or possibly one and a half Hershey bars. She is a wheaten terrior and is about 45 pounds. Will she be ok? What should I do?
A Hershey bar weighs 1.55 ounces, so let's say all of the is chocolate (I'm assuming you're talking about a milk chocolate Hershey bar). If she ate one and a half of them, that would be between 2 and 3 ounces of chocolate. According to my chocolate toxicity calculator, she should be OK with this dose. You might see some mild GI upset, such as vomiting and diarrhea. I would withhold food for several hours to see how she does, and take her to the vet if you see any stomach upset. I have seen one or two dogs who were exceptionally sensitive to even small amounts of chocolate, although this is rare. If you want to be completely safe you are within a good window of time to take her to your vet's and have vomiting induced.

My 6 month old Chihuahua ate a half of a stackers pill which is a energy pill for someone on a diet. He weighs 3-5 lbs.
Thank you for the clarification. These contain caffeine, which is toxic to dogs. Given Baby's small size, it wouldn't take as much caffeine to cause a problem. You still need to get her into a vet immediately.

If my half corgi dog ate a nestle crunch bar she will die
A 60 pound dog that ingested 2 ounces of milk chocolate is unlikely to die. This level of chocolate ingested may cause vomiting and diarrhea, but it should not last longer than 24 hours. If it does, Roza should see a vet. If she doesn't weight 60 pounds or you think she may have eaten more than 2 ounces of chocolate, post a new question with as much information as you can provide so we can help. Or choose a consultation so we can make sure we have all of the information we need to help you.

Our Shepard mix drank about a 12 oz cup of mocha cappuccino coffee drink. It has Dutched cocoa powder in it. Is this poisonous to the dog?
Oh dear! You're right that cocoa powder can certainly be toxic to dogs; coffee can as well, since they don't tolerate caffeine very well. But the good news is, I would not expect a single prepackaged coffee drink like this to contain enough of either one to cause any serious toxicity issues in a large-breed dog. It's possible that he may have some mild stomach upset if he isn't used to eating things like this, but otherwise I would not expect to see any serious problems. To be safe, it would be best to monitor him for the next 12 hours for any signs of toxicity - which would include repeated episodes of vomiting or diarrhea, restlessness or hyperactivity, muscle tremors, or even seizures. If you see anything that concerns you, you can always take him to the vet to be checked.

Dog ate chocolate covered coffee beans
In order to tell you whether your dog is in serious danger, we would need your dog's weight and the amount of beans eaten. Coffee beans contain 600mg of caffeine per oz, which is toxic. add theobromine from the chocolate (varies). If a 10lbs dog ate 1/2 oz of coffee beans he would have ingested a toxic amount. Please take your dog to a pet ER now, where they can make Rufio regurgitate the coffee beans, or call the following number: 24/7 Animal Poison Control Center 855-764-7661 $49 USD per incident fee applies

My dog ate a matcha tea powder single serving packet. The ingredients said it contains 50mg of caffeine. Should I be concerned? How do I help him?
This would not be a toxic dose of caffeine. I suppose the wrapper or the string could potentially become lodged in the gastrointestinal tract, but it would be very unlikely. I’d recommend monitoring for vomiting or a decrease in appetite and contacting your vet if noted.

Fray ate an ounce of chocolate and last thursday, she weighed about 13.9 pounds when we weighed her on the scale. She ate 1.2 ounces of chocolate, which in specific, was one of the REESES' Christmas lights that you can look up. Should she be okay
This amount of chocolate should not cause toxic complications but may cause gastrointestinal upset like vomiting or diarrhea from the sugar/fat content. I would monitor Fray closely and take her to a vet if these signs occur.

I left some miniature earth bars on my table and my red nosed full blooded pit ate every single one of them. He is a year old... Is he going to be ok or what should I do? It was about five of them
Hi and thanks for your question. If the earth bars had a lot of fat and/or chocolate in them, then that may be a concern. Chocolate can be quite toxic to dogs and a high amount of fat can cause stomach upset and pancreatitis. If the bars had raisins in them, that would also be a red flag. Raisins can cause renal failure in dogs. Macadamia nuts are also another toxic food found in health bars. If these contained anything mentioned above, you may want to see you veterinarian as soon as possible. I hope this helped.
